41. AMIGA XIII. HI properties
ID:
ivo://CDS.VizieR/J/A+A/609/A17
Title:
AMIGA XIII. HI properties
Short Name:
J/A+A/609/A17
Date:

Publisher:
CDS
Description:
We present the largest catalogue of HI single dish observations of isolated galaxies to date, as part of the multi-wavelength compilation being performed by the AMIGA project (Analysis of the interstellar Medium in Isolated GAlaxies). Despite numerous studies of the HI content of galaxies, no revision has been made for the most isolated L* galaxies since Haynes & Giovanelli (1984AJ.....89..758H). The AMIGA sample has been demonstrated to be almost "nurture free", therefore, by creating scaling relations for the HI content of these galaxies we will define a metric of HI normalcy in the absence of interactions. The catalogue comprises of our own HI observations with Arecibo, Effelsberg, Nancay and GBT, and spectra collected from the literature. In total we have measurements or constraints on the HI masses of 844 galaxies from the Catalogue of Isolated Galaxies (CIG). The multi-wavelength AMIGA dataset includes a revision of the B-band luminosities, optical diameters, morphologies, and isolation. Due to the large size of the catalogue, these revisions permit cuts to be made to ensure isolation and a high level of completeness, which was not previously possible. With this refined dataset we fit HI scaling relations based on luminosity, optical diameter and morphology. Our regression model incorporates all the data, including upper limits, and accounts for uncertainties in both variables, as well as distance uncertainties. The HI scaling relations of the AMIGA sample define an up-to-date metric of the HI content of almost "nurture free" galaxies. These relations allow the expected HI mass, in the absence of interactions, of an individual galaxy to be predicted to within 0.25dex (for typical measurement uncertainties). These relations are thus suitable for use as statistical measures of the impact of interactions on the neutral gas content of galaxies.

Title:
AMIGA XI. Optical nuclear activity

Publisher:
CDS
Description:
This study was performe within the frame of the AMIGA project (http://amiga.iaa.es/). We obtained spectral data from the 6th Data Release of the Sloan Digital Sky Survey, which were inspected in a semi-automatic way. We subtracted the underlying stellar populations from the spectra (using the software Starlight) and modelled the nuclear emission features. Standard emission-line diagnostics diagrams were applied, using a new classification scheme that takes into account censored data, to classify the type of nuclear emission. We provide a final catalogue of spectroscopic data, stellar populations, emission lines and classification of optical nuclear activity for AMIGA galaxies. The prevalence of optical active galactic nuclei (AGN) in AMIGA galaxies is 20.4%, or 36.7% including transition objects. The fraction of AGN increases steeply towards earlier morphological types and higher luminosities. We compare these results with a matched analysis of galaxies in isolated denser environments (Hickson Compact Groups). After correcting for the effects of the morphology and luminosity, we find that there is no evidence for a difference in the prevalence of AGN between isolated and compact group galaxies, and we discuss the implications of this result. We find that a major interaction is not a necessary condition for the triggering of optical AGN.
43. AMIGA X. Isolated galaxy colors

Title:
AMIGA X. Isolated galaxy colors
Short Name:
J/A+A/540/A47
Date:

Publisher:
CDS
Description:
The basic properties of galaxies can be affected by both nature (internal processes) or nurture (interactions and effects of environment). Deconvolving the two effects is an important current effort in astrophysics. Observed properties of a sample of isolated galaxies should be mainly the result of internal (natural) evolution. It follows that nurture-induced galaxy evolution can only be understood through a comparative study of galaxies in different environments. We take a first look at SDSS (g-r) colors of galaxies in the AMIGA sample, which consists of many of the most isolated galaxies in the local Universe. This alerted us at the same time the pitfalls of using automated SDSS colors.
44. AMUSING++ nearby galaxy compilation. I. Sample

Title:
AMUSING++ nearby galaxy compilation. I. Sample
Short Name:
J/AJ/159/167
Date:

Publisher:
CDS
Description:
We present here the All-weather MUse Supernova Integral-field of Nearby Galaxies (AMUSING++): the largest compilation of nearby galaxies observed with the Multi Unit Spectroscopic Explorer (MUSE) integral-field spectrograph so far. This collection consists of 635 galaxies from different MUSE projects covering the redshift interval 0.0002<z<0.1. The sample and its main properties are characterized and described here. It includes galaxies of almost all morphological types, with a good coverage in its color-magnitude diagram, within the stellar mass range between 10^8^ and 10^12^M{sun}, and with properties resembling those of a diameter-selected sample. The AMUSING++ sample is, therefore, suitable for studying, with unprecedented detail, the properties of nearby galaxies at global and local scales, providing us with more than 50 million individual spectra. We use this compilation to investigate the presence of galactic outflows. We exploit the use of combined emission-line images to explore the shape of the different ionized components and the distribution along classical diagnostic diagrams to disentangle the different ionizing sources across the optical extension of each galaxy. We use the cross-correlation function to estimate the level of symmetry of the emission lines as an indication of the presence of shocks and/or active galactic nuclei. We uncovered a total of 54 outflows, comprising ~8% of the sample. A large number of the discovered outflows correspond to those driven by active galactic nuclei (~60%), suggesting some bias in the selection of our sample. No clear evidence was found that outflow host galaxies are highly star-forming, and outflows appear to be found within all galaxies around the star-formation sequence.

Title:
An Optical Catalogue of Radio Galaxies
Short Name:
VIII/3
Date:

Publisher:
CDS
Description:
This catalog contains basic optical information on all known radio galaxies (with L[radio] greater than about 10**[41] ergs/s) that had been identified as of 1979 and for which measured redshifts were available. The data include the right ascension and declination (1950); galaxy (optical) type; visual magnitude; photoelectric colors; redshift (z) and the spectral lines on which the redshift measurements were based; coordinate designations; radio flux and frequency; radio spectral index; other names; and the references for the galaxy identification, photometric data, redshift, radio flux, radio spectral index, and radio map number. Note that the ADC version of this catalog differs somewhat from the original printed catalog in that some fields were added or modified and other fields reordered. In addition to the catalog data file itself, two additional files containing the list of references for the catalog are also available. The first reference list is in alphabetical order, and the second is in numerical order.
46. An X-ray catalog and atlas of galaxies.

Title:
An X-ray catalog and atlas of galaxies.
Short Name:

Publisher:
CDS
Description:
An X-ray catalog and atlas of galaxies observed with the Einstein Observatory imaging instruments (IPC and HRI) are presented. The catalog comprises 493 galaxies, including targets of pointed observations, and RSA or RC2 galaxies serendipitously included in Einstein fields. A total of 450 of these galaxies were imaged well within the instrumental fields, resulting in 238 detections and 2123 sigma upper limits. The other galaxies were either at the edge of the visible field of view or confused with other X-ray sources. For these a rough measure of their X-ray emission is also given. The atlas shows X-ray contour maps of detected galaxies superposed on optical photographs and gives azimuthally averaged surface brightness profiles of galaxies detected with a high signal-to-noise ratio.

49. APS Galaxies in the North Galactic Pole

Title:
APS Galaxies in the North Galactic Pole
Short Name:
VII/214
Date:
21 Oct 2021
Publisher:
CDS
Description:
(of PhD Thesis, from Minessota) I am using the Minnesota Automated Plate Scanner (APS) to construct two galaxy catalogs. The Minnesota Automated Plate Scanner Pisces-Perseus Survey (MAPS-PP) is used to search for modern-day remnant signatures of large-scale structure formation processes, specifically, galaxy alignments relative to surrounding large-scale structure. Weak evidence for such alignments is found, although the type of alignments seen don't strongly support any one large-scale structure formation model. Comparison of the MAPS-PP to pre-existing galaxy catalogs has led to the discovery that the Uppsala General Catalog and Third Reference Catalog of Galaxies exhibit a very strong measurement bias: their diameters are measured to different isophotes at different galaxy inclinations. Therefore previous determinations of the diameter function and the internal extinction properties of other galaxies (most of which have relied on one of these two galaxy catalogs) have suffered from a biased diameter measurement. I avoid this bias by using the APS data (which is obtained using automated computer-based criteria for measuring the structural properties of images digitized from photographic plates) to construct a catalog of over 200,000 galaxies within 30 degrees of the North Galactic Pole (the MAPS-NGP). The MAPS-NGP is the deepest galaxy catalog constructed over such a large area of the sky and used to re-evaluate previous investigations of the internal extinction in galaxies.
