First release of the IPHAS catalogue of new extended planetary nebulae

Date of Acceptance: 30/06/2014We present the first results of our search for new, extended planetary nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the Isaac Newton Telescope Photometric Ha Survey of the Northern Galactic plane (IPHAS). The newly uncovered PNe will help to improve the census of this important population of Galactic objects that serve as key windows into the late-stage evolution of low- to intermediate-mass stars. They will also facilitate study of the faint end of the ensemble Galactic PN luminosity function. The sensitivity and coverage of IPHAS allows PNe to be found in regions of greater extinction in the Galactic plane and/or those PNe in a more advanced evolutionary state and at larger distances compared to the general Galactic PN population. Using a set of newly revised optical diagnostic diagrams in combination with access to a powerful, new, multiwavelength imaging data base, we have identified 159 true, likely and possible PNe for this first catalogue release. The ability of IPHAS to unveil PNe at low Galactic latitudes and towards the Galactic Anticentre, compared to previous surveys, makes this survey an ideal tool to contribute to the improvement of our knowledge of the whole Galactic PN population.Peer reviewe

The research problem in this research includes whether there is the influence of rape news of UGM female student in Tribunnews.com towards female students vigilant attitude in interact and how the influence imposed. Variable X in this research is rape news, while vigilant attitude of female students in interact is variable Y. Quantitative research is implemented by means of associative type. In addition, the basic research is survey method. The population in this study is female students second period of KKN 2018/2019 University of Muhammadiyah Malang and 36 of them become the research sample. Questionnaires and documentation are implemented as data collection techniques. Validity and reliability test are also implemented as the research instrument test. Furthermore, the researcher conducts simple linear regression and hypothesis testing using the t test as data analysis techniques. The coefficient of variable X is 0.716 (positive). From the analysis results obtained that R square result (the coefficient of determination) is 0.130. R value (the correlation coefficient) is 0.361, it shows the correlation between news rape of UGM female student in Tribunnews.com towards female students vigilant attitude in interact (Y) are included in a weak category. On the other hand, t table (α = 0.05; df residual = 34) is 1.690. Since t arithmetic > t table is 2.255 > 1.690 or sig. t value (0.031) < α = 0.05, the influence of X (rape news of UGM female student in Tribunnews.com) towards Y (female students vigilant attitude in interact) is significant. In accordance with the analysis above, it can be concluded that 13% of female students vigilant attitude in interact variable (Y) is influenced by independent variable, namely rape news of UGM female student in Tribunnews.com, and yet 87% of female students vigilant attitude in interact variable is influenced by other variables

The AAO/UKST SuperCOSMOS Ha survey

The definitive version is available at www.blackwell-synergy.com. Copyright Blackwell Publishing DOI : 10.1111/j.1365-2966.2005.09350.xThe UK Schmidt Telescope (UKST) of the Anglo-Australian Observatory completed a narrow-band H plus [NII] 6548, 6584°A survey of the Southern Galactic Plane and Magellanic Clouds in late 2003. The survey, which was the last UKST wide-field pho- tographic survey, and the only one undertaken in a narrow band, is now an on-line digital data product of the Wide-Field Astronomy Unit of the Royal Observatory Ed- inburgh (ROE). The survey utilised a high specification, monolithic H interference band-pass filter of exceptional quality. In conjunction with the fine grained Tech-Pan film as a detector it has produced a survey with a powerful combination of area cover- age (4000 square degrees), resolution (∼1 arcsecond) and sensitivity (≤5 Rayleighs), reaching a depth for continuum point sources of R ≃ 20.5. The main survey consists of 233 individual fields on a grid of centres separated by 4◦ at declinations below +2◦ and covers a swathe approximately 20◦ wide about the Southern Galactic Plane. The original survey films were scanned by the SuperCOSMOS measuring machine at the Royal Observatory, Edinburgh to provide the on-line digital atlas called the SuperCOSMOS H Survey (SHS).Peer reviewe

Endoureterotomy by intraluminal invagination for nonmalignant ureterointestinal anastomotic strictures: Description of a new surgical technique and long-term followup

As part of a systematic search programme of a 10 wide strip of the northern Galactic plane, we present preliminary evidence for the discovery of four (and possibly five) new supernova remnants (SNRs). The pilot search area covered the 19-20 h right ascension zone sampling from +20 to +55 in declination using binned mosaic images from the Isaac Newton Telescope Photometric H? Survey (IPHAS). The optical identification of the candidate SNRs was based mainly on their filamentary and arc-like emission morphologies, their apparently coherent, even if fractured, structure and clear disconnection from any diffuse neighbouring H II region type nebulosity. Follow-up optical spectroscopy was undertaken, sampling carefully across prominent features of these faint sources. The resulting spectra revealed typical emission-line ratios for shock-excited nebulae which are characteristic of SNRs, which, along with the latest diagnostic diagrams, strongly support the likely SNR nature of these sources: G038.7-1.3 (IPHASX J190640.5+042819), G067.6+0.9 (IPHASX J195744.9+305306), G066.0-0.0 (IPHASX J195749.2+290259) and G065.8-0.5 (IPHASX J195920.4+283740). A fifth possible younger, higher density nebula SNR candidate, G067.8+0.5 (IPHASX J200002.4+305035), was discovered ?5 arcmin to the west of IPHASX J195744.9+305306, and it warrants further study. A multiwavelength cross-check from available archived data in the regions of these candidates was also performed with a focus on possible radio counterparts. A close positional match between previously unrecognized radio structures at several frequencies and across various components of the H? optical image data was found for all SNR candidates. This lends further direct support for the SNR nature of these objects. Evolved SNRs may have very weak and/or highly fragmented radio emission which could explain why they had not been previously recognized, but the association becomes clear in combination with the optical emission.

High-resolution Hα imaging of the northern Galactic plane and the IGAPS image database

The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys IPHAS and UVEX based on data from the Isaac Newton Telescope (INT) obtained between 2003 and 2018. It captures the entire northern Galactic plane within the Galactic coordinate range |b|< 5° and 30° < ℓ < 215°. From the beginning, the incorporation of narrow-band Hα imaging has been a unique and distinctive feature of this effort. Alongside a focused discussion of the nature and application of the Hα data, we present the IGAPS world-accessible database of images for all five survey filters, i, r, g, URGO, and narrow-band Hα, observed on a pixel scale of 0.33 arcsec and at an effective (median) angular resolution of 1.1−1.3 arcsec. The background, noise, and sensitivity characteristics of the narrow-band Hα filter images are outlined. Typical noise levels in this band correspond to a surface brightness at full ∼1 arcsec resolution of around 2 × 10−16 erg cm−2 s−1 arcsec−2. Illustrative applications of the Hα data to planetary nebulae and Herbig-Haro objects are outlined and, as part of a discussion of the mosaicking technique, we present a very large background-subtracted narrow-band mosaic of the supernova remnant Simeis 147. Finally, we lay out a method that exploits the database via an automated selection of bright ionised diffuse interstellar emission targets for the coming generation of wide-field massive-multiplex spectrographs. Two examples of the diffuse Hα map output from this selection process are presented and compared with previously published data

VPHAS+ DR2 survey

The Second VPHAS data release (DR2) covers the first 21 months of data-taking in which the survey progressed to 24 percent completion. Much of the Galactic mid-plane is now covered (especially in the r, i and Hα filters). This images release supersedes DR1. The full description of the catalogue, including a discussion of how the catalogue was made and advice on best use of the data, is available as file vphas-dr2-desc.pdf (ftp://cdsarc.u-strasbg.fr/pub/cats/II/341/vphas-dr2-desc.pdf). The current photometric scale is linked to APASS in g, r and i, while the u and Hα bands are calibrated by local offsetting from g and r.
