ALCS is an extensive survey of well-studied lensing clusters with ALMA, covering an area of 133 arcmin(2) over 33 clusters with a 1.2 mm flux-density limit of similar to 60 mu Jy (1 sigma). Utilizing the archival data of Chandra, we identify three AGNs at z = 1.06, 2.09, and 2.84 among the 180 millimeter sources securely detected in the ALCS (of which 155 are inside the coverage of Chandra). The X-ray spectral analysis shows that two AGNs are not significantly absorbed (log N-H cm (2) 100 Me yr-1). This demonstrates that a wide-area survey with ALMA and Chandra can selectively detect intense growth of both galaxies and supermassive black holes in the high-redshift universe.Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT) Japan Society for the Promotion of Science Grants-in-Aid for Scientific Research (KAKENHI) A-FQM-510-UGR20NAOJ ALMA Scientific Research 22J22795RIKEN Special Postdoctoral Researcher ProgramNRAO Student Observing Support (SOS) 20H01946Villum Fonden 17H06130 19K14759Cosmic Dawn Center of Excellence - Danish National Research Foundation 22H01266Ministry of Science and Innovation, Spain (MICINN) Spanish GovernmentJunta de AndaluciaFEDER/Junta de Andalucia-Consejeria de Transformacion Economica, Industria, Conocimiento y UniversidadesMCIN/AEI 2017-06B, SOSPA7-022, 13160, 37440, 140, 20H01953, BG20/00224, PID2020-114414GB-100, PID2020-113689GB-I00, P20_0033

    Y.K., T.S., and the other authors thank the ALMA staff for their kind support. This work was supported by the ALMA Japan Research Grant of NAOJ Chile Observatory, NAOJALMA-0114. D.E. acknowledges support from a Beatriz Galindo senior fellowship (BG20/00224) from the Spanish Ministry of Science and Innovation. This paper makes use of the following ALMA data: ADS/JAO.ALMA#2013.0.01172. S. ALMA is a partnership of ESO (representing its member states), NSF (USA) and NINS (Japan), together with NRC (Canada), MOST and ASIAA (Taiwan), and KASI (Republic of Korea), in cooperation with the Republic of Chile. The Joint ALMA Observatory is operated by ESO, AUI/NRAO, and NAOJ. This NVAS image was produced as part of the NRAO VLA Archive Survey, (c) AUI/NRAO. This research has made use of the NASA/IPAC Extragalactic Database (NED), which is funded by the National Aeronautics and Space Administration and operated by the California Institute of Technology. This work is based in part on observations made with the Spitzer Space Telescope, which is operated by the Jet Propulsion Laboratory, California Institute of Technology under a contract with NASA.We present Atacama Large Millimeter/submillimeter Array observations of multiple (CO)-C-12, (CO)-C-13, and (CO)-O-18 lines and 2.9 mm and 1.3 mm continuum emission toward the nearby interacting luminous infrared galaxy NGC 3110, supplemented with similar spatial resolution H alpha, 1.4 GHz continuum, and K-band data. We estimate the typical CO-to-H-2 conversion factor of 1.7 M (circle dot) (K km s(-1) pc(2))(-1) within the disk using local thermal equilibrium-based and dust-based H-2 column densities, and measure the 1 kpc scale surface densities of the star formation rate (sigma(SFR)), super star clusters (sigma(SSC)), molecular gas mass, and star formation efficiency (SFE) toward the entire gas disk. These parameters show a peak in the southern part of the southern spiral arm (SFE similar to 10(-8.2) yr(-1), sigma(SFR) similar to 10(-0.6) M (circle dot) kpc(-2) yr(-1), sigma(SSC) similar to 6.0 kpc(-2)), which is likely attributable to the ongoing tidal interaction with the companion galaxy MCG-01-26-013, as well as toward the circumnuclear region. We also find that thermal free-free emission contributes to a significant fraction of the millimeter continuum emission at the position of the southern peak. These measurements imply that the peak of the southern arm is an active and young star-forming region, whereas the central part of NGC 3110 is a site of long-continued star formation. We suggest that during the early stage of the galaxy-galaxy interaction in which the mass ratio was high in NGC 3110, fragmentation along the main galaxy arms is an important driver of merger-induced star formation, and that massive gas inflow results in dusty nuclear starbursts.ALMA Japan Research Grant of NAOJ Chile Observatory NAOJALMA-0114Spanish Government BG20/00224National Aeronautics & Space Administration (NASA

    ALMA Lensing Cluster Survey: Hubble Space Telescope and Spitzer Photometry of 33 Lensed Fields Built with CHArGE

    We present a set of multiwavelength mosaics and photometric catalogs in the Atacama Large Millimeter/ submillimeter Array (ALMA) lensing cluster survey fields. The catalogs were built by the reprocessing of archival data from the Complete Hubble Archive for Galaxy Evolution compilation, taken by the Hubble Space Telescope (HST) in the Reionization Lensing Cluster Survey, Cluster Lensing And Supernova survey with Hubble, and Hubble Frontier Fields. Additionally, we have reconstructed the Spitzer Infrared Array Camera 3.6 and 4.5 μm mosaics, by utilizing all the available archival IPAC Infrared Science Archive/Spitzer Heritage Archive exposures. To alleviate the effect of blending in such a crowded region, we have modeled the Spitzer photometry by convolving the HST detection image with the Spitzer point-spread function using the novel GOLFIR software. The final catalogs contain 218,000 sources, covering a combined area of 690 arcmin2, a factor of ∼2 improvement over the currently existing photometry. A large number of detected sources is a result of reprocessing of all available and sometimes deeper exposures, in conjunction with a combined optical–near-IR detection strategy. These data will serve as an important tool in aiding the search of the submillimeter galaxies in future ALMA surveys, as well as follow-ups of the HST dark and high-z sources with JWST. Coupled with the available HST photometry, the addition of the 3.6 and 4.5 μm bands will allow us to place a better constraint on the photometric redshifts and stellar masses of these objects, thus giving us an opportunity to identify high-redshift candidates for spectroscopic follow-ups and to answer the important questions regarding the Epoch of Reionization and formation of the first galaxies.

The object is detected in Hubble Space Telescope imaging taken for the RELICS program. It appears to have a quasi-stellar nucleus consistent with a point-source, with a de-magnified radius of re ≲ 100 pc. The object is spectroscopically confirmed to be an AGN at z spec = 2.063 ± 0.005 showing broad rest-frame UV emission lines, and detected in both X-ray observations with Chandra and in ALCS ALMA band 6 (1.2 mm) imaging. It has a relatively faint rest-frame UV luminosity for a quasar-like object, MUV, 1450 = −19.7 ± 0.2. The object adds to just a few quasars or other X-ray sources known to be multiply lensed by a galaxy cluster. Some diffuse emission from the host galaxy is faintly seen around the nucleus, and there is a faint object nearby sharing the same multiple-imaging symmetry and geometric redshift, possibly an interacting galaxy or a star-forming knot in the host. We present an accompanying lens model, calculate the magnifications and time delays, and infer the physical properties of the source. We find the rest-frame UV continuum and emission lines to be dominated by the AGN, and the optical emission to be dominated by the host galaxy of modest stellar mass M✶ ≃ 109.2 M⊙. We also observe some variation in the AGN emission with time, which may suggest that the AGN used to be more active. This object adds a low-redshift counterpart to several relatively faint AGN recently uncovered at high redshifts with HST and JWST.Horizon 2020 Framework Programme H2020Consejería de Transformación Económica, Industria, Conocimiento y Universidades 13160, 37440Science and Technology Facilities Council ST/W001438/1 STFCEuropean Research Council ERCFondo Nacional de Desarrollo Científico y Tecnológico 1190818, 1200495, ICN12_009 FONDECYTMinisterio de Ciencia e Innovación MCIN/AEI/10.13039/501100011033, P20-00334, PID2020-113689GB-I00, PID2020-114414GB-100 MICINNHorizon 2020 789056European Regional Development Fund ERDFJunta de Andalucía A-FQM-510-UGR2

    A postura dos professores de Educação Física em relação ao trabalho cooperativo e à centralidade do aluno na experiência de aprendizagem

    O trabalho cooperativo propicia uma melhora na aprendizagem, na interação e na comunicação entre os estudantes. Portanto, o objetivo desta pesquisa é analisar a postura dos professores de Educação Física em relação à aprendizagem cooperativa a fim de aprimorar as experiências de ensino cuja centralidade esteja no aluno. Nossa amostra inclui 455 professores de Educação Física (70,8% homens, 29,2% mulheres, cuja idade varia de 30 a 50). Foi realizada uma análise estatística inferencial, com o uso de testes distintos (ANOVA e Welch). Os resultados desta pesquisa mostram que a postura dos professores de escolas públicas é mais positiva do que a dos professores de escolas semiprivadas no que se refere ao aumento da responsabilidade (p=.002) e aos debates em grupo. Além disso, os professores de escolas públicas consideram que a aprendizagem cooperativa em seu ambiente de trabalho traz mais benefícios à comunicação em grupo (p=.000) e à coesão do trabalho grupal (p=.001) do que no ambiente de trabalho das escolas semi-privadas e privadas. Constatou-se, também, que os professores com menos experiência docente têm uma postura mais positiva em relação à aprendizagem cooperativa do que seus colegas mais experientes, pois os primeiros consideram que este método contribui para o desenvolvimento de uma série de habilidades dos alunos, tais como a interação social, o desenvolvimento de hábitos de convivência, responsabilidade e corresponsabilidade, melhores relações interpessoais, debates em grupo etc.Cooperative tasks enhance learning, interaction and communication amongst students. Thus, this research aims to analyze the attitude of Physical Education teachers towards cooperative learning and possible improvements in different qualities in relation to ownership of the teaching center and teaching experience. The sample was made up of 455 Physical Education teachers (70.8% men and 29.2% women, aged from 30 to 50), and an inferential statistical analysis was carried out using different tests (ANOVA and Welch). The results of this investigation show that the attitude of the teachers who work in state schools is more positive than those working in semi-private schools as regards improvement of responsibility (p=.002) and group discussion (p=.000). Additionally, teachers who teach in state schools consider that cooperative learning improves group communications (p=.000) and group cohesion (p=.001) to a greater extent than teachers who work in semi-private and private schools. Moreover, the teachers with less teaching experience have a more positive attitude towards cooperative learning than the teachers who have more teaching experience, because the former consider that this method improves different skills in the students, such as socialization and social interaction, the acquisition of habits of coexistence, responsibility and co-responsibility, interpersonal relationships, group discussion, etc

    The central parsecs of M87: jet emission and an elusive accretion disc

    Full text link
    We present the first simultaneous spectral energy distribution (SED) of M87 core at a scale of 0.4 arcsec (∼32 pc\sim 32\, \rm{pc}) across the electromagnetic spectrum. Two separate, quiescent, and active states are sampled that are characterized by a similar featureless SED of power-law form, and that are thus remarkably different from that of a canonical active galactic nuclei (AGN) or a radiatively inefficient accretion source. We show that the emission from a jet gives an excellent representation of the core of M87 core covering ten orders of magnitude in frequency for both the active and the quiescent phases. The inferred total jet power is, however, one to two orders of magnitude lower than the jet mechanical power reported in the literature. The maximum luminosity of a thin accretion disc allowed by the data yields an accretion rate of <6×10−5 M⊙ yr−1< 6 \times 10^{-5}\, \rm{M_\odot \, yr^{-1}}, assuming 10% efficiency. This power suffices to explain M87 radiative luminosity at the jet-frame, it is however two to three order of magnitude below that required to account for the jet's kinetic power. The simplest explanation is variability, which requires the core power of M87 to have been two to three orders of magnitude higher in the last 200 yr. Alternatively, an extra source of power may derive from black hole spin. Based on the strict upper limit on the accretion rate, such spin power extraction requires an efficiency an order of magnitude higher than predicted from magnetohydrodynamic simulations, currently in the few hundred per cent range.Comment: 18 pages, 6 figures.

    Modelo integrador para personas con adicción a sustancias psicoactivas

    Get PDF
    Los trastornos por abuso de drogas constituyen en la actualidad uno de los problemas de salud pública más importantes. El abuso de una sustancia conlleva el daño físico, el daño psicológico y el daño social, tanto para la persona que consume la droga como para los demás. En el campo de la salud mental normalmente no hay un factor único que explique la patología y en el de las adicciones en particular no hay una razón única por la dependencia, sino que son varios los factores [genéticos, ambientales, familiares, sociales y psicológicos] que están detrás de ella. Y por lo tanto sería lícito considerar que tampoco hay una sola terapia que ayude a los afectados. El tratamiento específi co para las adicciones que ha sido desde siempre la terapia cognitivo conductual, posiblemente no sea la única intervención en esta problemática. Los últimos estudios revelan la importancia y efi cacia de las terapias psicológicas conductuales a largo plazo, combinadas o no con apoyo farmacológico. Concretamente el mayor soporte empírico son: la Aproximación de Reforzamiento Comunitario (CRA), el Entrenamiento en Habilidades Sociales, la Prevención de Recaídas (PR) y la terapia conductual familiar y de pareja. Con los matices que en algunos casos se mencionarán, se podrían considerar tratamientos bien establecidos. Además, estos programas coinciden en ser también los que ofrecen una mejor relación coste/benefi cio (Roth y Fonagy, 1996). La multiplicidad de terapias no debe entenderse como un problema, sino como un enriquecimiento, siempre y cuando no se conviertan cada una en compartimentos estancos, que excluyan los elementos favorables de otros para el caso concreto. Por tanto, hay un conocimiento amplio y una fl exibilidad inclusiva teniendo en cuenta la variabilidad intraindividual de los pacientes.Lambert, Shapiro y Bergin (1986, citados en Feixas y Jarque, 2010) nos hacen las siguientes aportaciones respecto al cambio terapéutico: éste debe ser multidimensional (evalúa diversas dimensiones de una patología), debe tener referencias teóricas que permitan organizar el cambio que queremos captar, debe tener criterios de cambio con resultados individualizados (serían, pero menos efectivos), y fi nalmente el cambio debe ser relevante clínicamente, es decir que implique una mejora real. El objetivo de este artículo es dar a conocer la propuesta globalizadora que se lleva a cabo en CC Adicciones de estos distintos tipos de reforzamientos y entrenamientos en una única institución formada por un equipo disciplinar que acompaña al paciente en cada fase y circunstancia del tratamiento. No obstante se necesitarán estudios a largo plazo y de casos para confi rmar la efi cacia de este programa por otro lado pionero en Catalunya.Substance abuse disorders are currently one of the major public health problems. Substance abuse involves physical harm, psychological harm and social harm, both for the person who takes the drug and for others. In the fi eld of mental health there is usually no single factor that explains the pathology and as regards addiction in particular there is no single reason for the dependency: there are instead several factors [genetic, environmental, familial, social and psychological ] lying behind this. And it would therefore be legitimate to consider that there is no single therapy to help those affected. Specifi c treatment for addiction has always been cognitive behavioral therapy, but this may not be the only intervention in this problem. Recent studies show the importance and effectiveness of long-term psychological behavioral therapies, combined or not with pharmacological support. The greatest empirical supports are specifi cally: the Community Reinforcement Approach (CRA), Social Skills Training, Relapse Prevention (RP) and behavioral family therapy and couple therapy. With slight differences in some cases that will be mentioned, these could be considered well-established treatments. In addition, these programs also coincide in being the ones with best cost / benefi t ratio (Roth and Fonagy, 1996). The multiplicity of therapies should not be seen as a problem but as enrichment, provided they do not each become separate compartments, excluding elements favorable to the case from others. There is thus broad and inclusive fl exibility in view of intra-patient variabilityLambert, Shapiro and Bergin (1986, cited in Feixas and Jarque, 2010) make the following contributions to the therapeutic change: it must be multidimensional (assessing various dimensions of a disease), must have theoretical references that can organize the change we want to implement, must have change criteria with individualized results (they would otherwise be less effective), and fi nally the change should be clinically relevant, involving real improvement. The aim of this paper is to present the globalizing proposal of these different types of reinforcements and training at a single institution made up of a disciplinary team accompanying the patient at every stage and circumstance of the treatment. It will however take long-term studies and cases to confi rm the effectiveness of this program which is on the other hand a ground-breaking system in Catalonia
