2261. Catalogue of 2700 double stars
ID:
ivo://CDS.VizieR/I/209A
Title:
Catalogue of 2700 double stars
Short Name:
I/209A
Date:
21 Oct 2021
Publisher:
CDS
Description:
This catalog contains a compilation of measurements of binary stars discovered by Paul Couteau between 1951 and 1993. For each star, it contains a reference number to identify the star in the catalog, the Cou number, the visual magnitudes of the components, positions for 1900, 1950, and 2000, the identification of the star in the BD or in the Carte du Ciel, the magnitude from that catalog, remarks such as the proper motion, a system to which the binary belongs or its position with respect to a neighboring BD star and for many stars, the spectral type. For each observation, the data given are the date, position angle, separation, telescope size, number of observations, and the observer. Sometimes the magnitudes estimated by the observer are also given. The present description DOES NOT replace the documents referenced above. It just provides a short format description of the files making up this catalogue.

Title:
Catalogue of eclipsing binaries in the SMC
Short Name:
J/MNRAS/331/609
Date:

Publisher:
CDS
Description:
The catalogue lists 167 eclipsing binary stars in the Small Magellanic Cloud detected in the database of time-series photometry for 400000 SMC stars acquired by the Microlensing Observations in Astrophysics (MOA) project during 1997. Coordinates, ephemerides, magnitudes and light curves are presented. Thirty-five systems are new detections. The limiting magnitude is about 17.5. The majority of periods lie within the range 0.4 to 20 days; 6 systems are possibly eccentric while 14 are probably or certainly so. The majority of the newly-identified systems lie in the outer regions of the SMC.

2266. Catalogue of extended objects in Magellanic Clouds
ID:

Title:
Catalogue of extended objects in Magellanic Clouds
Short Name:
J/MNRAS/389/678
Date:

Publisher:
CDS
Description:
We update the Small Magellanic Cloud (SMC), Bridge and Large Magellanic Cloud (LMC) catalogues of extended objects that were constructed by members of our group from 1995 to 2000. In addition to the rich subsequent literature for the previous classes, we now also include HI shells and supershells. A total of 9305 objects were cross-identified, while our previous catalogues amounted to 7900 entries, an increase of ~12 per cent. We present the results in subcatalogues containing 1445 emission nebulae, 3740 star clusters, 3326 associations and 794 HI shells and supershells. Angular and apparent size distributions of the extended objects are analysed. We conclude that the objects, in general, appear to respond to tidal effects arising from the LMC, SMC and Bridge. Number-density profiles extracted along directions parallel and perpendicular to the LMC bar, can be described by two exponential-discs. A single exponential-disc fits the equivalent SMC profiles. Interestingly, when angular-averaged number-densities of most of the extended objects are considered, the profiles of both Clouds do not follow an exponential-disc. Rather, they are best described by a tidally truncated, core/halo profile, despite the fact that the Clouds are clearly disturbed discs. On the other hand, the older star clusters taken isolately, distribute as an exponential disc. The present catalogue is an important tool for the unambiguous identification of previous objects in current CCD surveys and to establish new findings.

2268. Catalogue of faint local radio AGN
ID:
ivo://CDS.VizieR/J/MNRAS/479/807
Title:
Catalogue of faint local radio AGN
Short Name:
J/MNRAS/479/807
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a catalogue of 2210 local (z<0.1) galaxies that contain faint active galactic nuclei (AGN). We select these objects by identifying galaxies that exhibit a significant excess in their radio luminosities, compared to what is expected from the observed levels of star formation activity in these systems. This is achieved by comparing the optical (spectroscopic) star formation rate (SFR) to the 1.4GHz luminosity measured from the Faint Images of the Radio Sky at Twenty centimeters survey. The majority of the AGN identified in this study are fainter than those in previous work, such as in the Best and Heckman (2012, Cat. J/MNRAS/421/1569) catalogue. We show that these faint AGN make a non-negligible contribution to the radio luminosity function at low luminosities (below 10^22.5^W/Hz), and host ~13 per cent of the local radio luminosity budget. Their host galaxies are predominantly high stellar-mass systems (with a median stellar mass of 1011 M), are found across a range of environments (but typically in denser environments than star-forming galaxies) and have early-type morphologies. This study demonstrates a general technique to identify AGN in galaxy populations where reliable optical SFRs can be extracted using spectro-photometry and where radio data are also available so that a radio excess can be measured. Our results also demonstrate that it is unsafe to infer SFRs from radio emission alone, even if bright AGN have been excluded from a sample, since there is a significant population of faint radio AGN that may contaminate the radio-derived SFRs.
2269. Catalogue of far-infrared loops in the Galaxy
ID:
ivo://CDS.VizieR/J/A+A/463/1227
Title:
Catalogue of far-infrared loops in the Galaxy
Short Name:
J/A+A/463/1227
Date:
21 Oct 2021
Publisher:
CDS
Description:
An all-sky survey of loop- and arc-like intensity enhancements has been performed in order to investigate the large-scale structure of the diffuse far-infrared emission. We used maps made of 60 and 100um processed IRAS data (Sky Survey Atlas and dust infrared emission maps) to identify large-scale structures: loops, arcs or cavities, in the far-infrared emission in the Galaxy. Distances were attributed to a subsample of loops using associated objects. We identified 462 far-infrared loops, analyzed their individual FIR properties and their distribution. This data forms the Catalogue of Far-Infrared Loops in the Galaxy. We obtained observational estimates of f_in~30% and f_out~5% for the hot gas volume filling factor of the inward and outward Galactic neighbourhood of the Solar System. We obtained a slope of the power law size luminosity function {beta}=1.37 for low Galactic latitudes in the outer Milky Way. Deviations in the celestial distribution of far-infrared loops clearly indicate, that violent events frequently overwrite the structure of the interstellar matter in the inner Galaxy. Our objects trace out the spiral arm structure of the Galaxy in the neighbourhood of the Sun and their distribution clearly suggests that there is an efficient process that can generate loop-like features at high Galactic latitudes. Power law indices of size luminosity distributions suggest, that the structure of the ISM is ruled by supernovae and stellar winds at low Galactic latitudes while it is governed by supersonic turbulence above the Galactic plane.
2270. Catalogue of features in the S4G
ID:
ivo://CDS.VizieR/J/A+A/582/A86
Title:
Catalogue of features in the S4G
Short Name:
J/A+A/582/A86
Date:
21 Oct 2021
Publisher:
CDS
Description:
A catalogue of the features for the complete Spitzer Survey of Stellar Structure in Galaxies (S4G), including 2352 nearby galaxies, is presented. The measurements are made using 3.6um images, largely tracing the old stellar population; at this wavelength the effects of dust are also minimal. The measured features are the sizes, ellipticities, and orientations of bars, rings, ringlenses, and lenses. Measured in a similar manner are also barlenses (lens-like structures embedded in the bars), which are not lenses in the usual sense, being rather the more face-on counterparts of the boxy/peanut structures in the edge-on view. In addition, pitch angles of spiral arm segments are measured for those galaxies where they can be reliably traced. More than one pitch angle may appear for a single galaxy. All measurements are made in a human- supervised manner so that attention is paid to each galaxy. We create a catalogue of morphological features in the complete S4G. We used isophotal analysis, unsharp masking, and fitting ellipses to measured structures. We find that the sizes of the inner rings and lenses normalized to barlength correlate with the galaxy mass: the normalized sizes increase toward the less massive galaxies; it has been suggested that this is related to the larger dark matter content in the bar region in these systems. Bars in the low mass galaxies are also less concentrated, likely to be connected to the mass cut-off in the appearance of the nuclear rings and lenses. We also show observational evidence that barlenses indeed form part of the bar, and that a large fraction of the inner lenses in the non-barred galaxies could be former barlenses in which the thin outer bar component has dissolved.
