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

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.

    BackgroundTobacco use prevalence rates are high among Spanish adolescents. Programming to counteract tobacco use is needed.Methods and findingsThe current study provides a one-year follow-up outcome evaluation of Project EX, an eight-session classroom-based curriculum. The intervention was tested using a randomized controlled trial with 1,546 Spanish students, involving three program and three control schools. Compared to the control condition, the program condition revealed a greater reduction in nicotine dependence (p < .05) and CO ppm levels (p < .001), and lower consumption of cigarettes at last month (p = .03).ConclusionsLong-term outcomes of the Project EX classroom-based program are promising for adolescent prevention and possibly cessation in Spain

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

    Diseño de un sistema de control de dirección de un vehículo

    El proyecto consta de dos partes diferenciadas, en la primera se desarrolla un sistema de control de dirección para una moto de Lego, basado en el seguimiento de una línea negra sobre una plantilla de color blanco. Para ello se compró un paquete de Lego Mindstorm NXT, con el que hemos construido la moto que se va a usar. Esta lleva instalada una cámara de video la cual capta las imágenes de la trayectoria de la línea negra que deberá seguir la moto y las envía al ordenador. El ordenador procesa las imágenes y envía por Bluetooth el valor del ángulo que debe girar la moto, esta variable es recibida por la CPU del Lego, que manda la señal de giro al motor paso a paso de la dirección. Este ciclo de control se va repitiendo en intervalos de décimas de segundo y de esta forma la moto se va guiando a través de la línea negra. El procesamiento de las imágenes se hace mediante el programa Matlab, que nos proporciona las herramientas necesarias para el tratamiento digital de imágenes. El envío de órdenes y la conexión del ordenador con la CPU de Lego se hacen posibles gracias al paquete de funciones, desarrollado por la Universidad de Aachen, que permite programar La CPU de Lego desde el Matlab. En la segunda parte del proyecto se lleva a cabo el cálculo de la inclinación de la moto, generando una señal que podría ser procesada posteriormente por un sistema de control de estabilidad. Para ello se han instalado en la moto un par de punteros láser, uno a cada lado de la moto, que se toman como puntos de referencia para obtener la inclinación. Las proyecciones de estos punteros son captadas por la cámara de la moto y varían de posición en la imagen según la inclinación de la moto.Ingeniería Técnica en Electrónic

    CO(J=1-0) Mapping Survey of 64 Galaxies in the Fornax Cluster with the ALMA Morita Array

    We conduct a 12C16O(J = 1−0) (hereafter CO) mapping survey of 64 galaxies in the Fornax cluster using the Atacama Large Millimeter/submillimeter Array Morita array in cycle 5. CO emission is detected from 23 out of the 64 galaxies. Our sample includes dwarf, spiral, and elliptical galaxies with stellar masses of Mstar ∼ 106.3−11.6 Me. The achieved beam size and sensitivity are 15″ × 8″ and ∼12 mJy beam−1 at the velocity resolution of ∼10 km s−1, respectively. We study the cold gas (molecular and atomic gas) properties of 38 subsamples with Mstar > 109 Me combined with literature H I data. We find that (1) the low star formation (SF) activity in the Fornax galaxies is caused by the decrease in the cold gas mass fraction with respect to stellar mass (hereafter, gas fraction) rather than the decrease of the SF efficiency from the cold gas; (2) the atomic gas fraction is more heavily reduced than the molecular gas fraction of such galaxies with low SF activity. A comparison between the cold gas properties of the Fornax galaxies and their environmental properties suggests that the atomic gas is stripped tidally and by the ram pressure, which leads to the molecular gas depletion with an aid of the strangulation and consequently SF quenching. Preprocesses in the group environment would also play a role in reducing cold gas reservoirs in some Fornax galaxies.Ministry of Education, Culture, Sports, Science and Technology, Japan (MEXT) Japan Society for the Promotion of ScienceGrants-in-Aid for Scientific Research (KAKENHI) 16H02158 JP17K14259 18H03717 19K03937 19J40004 19H01931 19H05076 20H05861 21H01128 21H04496Sumitomo Foundation 180923Collaboration Funding of the Institute of Statistical Mathematics "New Development of the Studies on Galaxy Evolution with a Method of Data Science"Ministry of Science and Innovation, Spain (MICINN) Spanish Government BG20/00224 MCIN/AEI PID2020-114414GB-100 PID2020-113689GB-I00Junta de Andalucia P20_00334FEDER/Junta de Andalucia-Consejeria de Transformacion Economica, Industria, Conocimiento y Universidades A-FQM-510-UGR20European Research Council (ERC) 679627 882793Australian Research Council CE170100013Korea Astronomy and Space Science Institute - Korean government (MSIT) 2022-1- 840-05National Aeronautics & Space Administration (NASA
