- Description:
- This Catalog of Star-Forming Regions in the Galaxy contains coordinates and fluxes of young objects in the radio and infrared, as well as data on the radial velocities of recombination and molecular lines, for more than three thousand star-forming regions. In addition to photometric and kinematic data, we present information on diffuse and reflecting nebulae, dark and molecular clouds, and other objects related to young stars. The catalog consists of two parts. The main catalog lists star-forming regions in order of Galactic longitude and is supplemented by analogous information for star-forming regions in complexes of dark clouds with large angular sizes that are closest to the Sun. In our preliminary study of the catalog data using a formal classification of the star-forming regions, we subdivided these objects into several classes and characterized them as being populated primarily by massive or low-mass stars at early or late stages of the star-formation process. We also distinguish between relatively nearby and distant complexes.

- Description:
- Almost every star in our Galaxy is likely to harbor a terrestrial planet, but accurate measurements of an exoplanet's mass and radius demand accurate knowledge of the properties of its host star. The imminent TESS and CHEOPS missions are slated to discover thousands of new exoplanets. Along with WFIRST, which will directly image nearby planets, these surveys make urgent the need to better characterize stars in the nearby solar neighborhood (<30pc). We have compiled the CATalog of Stellar Unified Properties (CATSUP) for 951 stars, including such data as: Gaia astrometry; multiplicity within stellar systems; stellar elemental abundance measurements; standardized spectral types; CaII H and K stellar activity indices; GALEX NUV and FUV photometry; and X-ray fluxes and luminosities from ROSAT, XMM, and Chandra. We use this data-rich catalog to find correlations, especially between stellar emission indices, colors, and galactic velocity. Additionally, we demonstrate that thick-disk stars in the sample are generally older, have lower activity, and have higher velocities normal to the galactic plane. We anticipate that CATSUP will be useful for discerning other trends among stars within the nearby solar neighborhood, for comparing thin-disk versus thick-disk stars, for comparing stars with and without planets, and for finding correlations between chemical and kinematic properties.

- 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.

- Publisher:
- CDS
- Description:
- A catalog of more than 300 late type stars which display maser line radio emission in OH, H2O or SiO molecules has been compiled. About two thirds of the objects have been identified with optical or infrared optics, mostly M-supergiants, Mira, or semiregular variables. The catalog contains optical data such as spectral type, period and magnitude, radio flux densities and velocities and infrared flux densities in the region between 0.7 and 20 micrometers.

- CDS
- Description:
- The first version of this catalogue was published in Abh.Hamburger Sternw. 1978, Vol.10, p 1ff. (CDS Catalogue II/129). A second version was published in 1987 (1987A&AS...69...87W) and microfiches (CDS Catalogue II/147). A third version was published 1995A&AS..109..177W (CDS Catalogue II/199). The basic concept of the earlier versions is preserved (in file "catalog.txt"), namely one entry per star per frequency per paper. Space is now provided, however, to add more informations. These may be of technical or astronomical nature. Usually month and year of observation and the number of independent data points or length of monitoring session are given. In the file "catalog.txt", all radio data are preceded by a header which contains information on the star or stellar system. (Note, that a physical stellar system is regarded as one single entry and that comments pertaining to individual components are found directly behind the observational data). Stellar data like names, position, proper motion, magnitudes and spectroscopic types are given in fixed format in a self-explanatory fashion. It is tried to have typical values from commonly available references. It is not intended to compete here with other compilations. These header informations are collected when the star is entered for the first time. They are only changed when new values are available while additional radio references are added. An arbitrarily expandable section for unformatted text finishes the header. Finally, the units of the radio data remain in MHz (column#1) and mJy (columns #2. and #3). All coordinates refer to epoch and equinox 1950.0 (e.g. B1950). This is a so-called merged version e.g. all stars, those detected at least once and those with upper limits only, are listed in order of ascending right ascension. The detected stars are marked with a "D" in the outermost right hand column in lines 1 to 5 ('D' in column "Det" of the file "stars.dat"). The last updating occurred on 2001-Mar-06. In this version stars have new running numbers.

- Catalogues from a deep 327 MHz Westerbork Survey
- Short Name:

- CDS
- Description:
- We present the results of a deep survey of six fields with the Westerbork Synthesis Radio Telescope at 327 MHz. In total we have detected ~4500 sources brighter than our 5-sigma noise level, which ranges from 2.4-3.5 mJy/beam, over an area of ~95 square degrees. For four fields we also obtained 608 MHz observations, for the remaining two fields 608 MHz observations were already available. We present the source catalogues at both frequencies and derive source counts and spectral indices. The data were calibrated using the DWARF redundancy package and absolute calibration is based on 3C286, using a flux of 26.93 Jy at 327 Mhz and 21.47 Jy at 608 MHz. The source parameters were determined using a gaussian fitting procedure for all but the most complex sources and statistical corrections for noise bias were applied. As part of my PhD-thesis at Leiden Observatory I made the following surveys at 327 and 608 MHz using the Westerbork Synthesis Radio Telescope: -------------------------------------------------------------------------- 64W2: Lynx, 327 MHz only (this field has been mapped at this frequency before by M.J.A. Oort (thesis), I've added a 2 after the W to indicate the revised list), numbers do not correspond because the present survey is more sensitive. 69W : Draco, a survey of 2 overlapping fields at 327 MHz and 6 fields at 608 MHz. 70W : Umi, 327 MHz only, one field. 75W : OH471, one 327 MHz field and three 608 MHz fields 76W : Cam, one 327 MHz field and three 608 MHz fields -------------------------------------------------------------------------- Sources detected at both frequencies have corresponding numbers in the 327 MHz (92cm) and 608 MHz (50cm) lists. Multiple sources are indicated by a '*' after the name, their components by 'A','B', etc. Components of multiple sources do not necessarily correspond between the two frequencies, also in some cases one or more components may not be detected at the other frequency. The .tex files are in plain TeX format The .dat files were written with the following format (fortran): FORMAT(A8,1X,F9.2,1X,F4.2,1X,F9.1,1X,F4.1,1X,F8.2,1X,F7.2,1X,A2, 1 1X,F5.1,1X,F4.1,1X,F4.0,1X,F3.0,1X,F5.1,1X,F5.2,1X,F7.2, 1 1X,F5.2,1X,F5.2)
