Galactic Cold Cores. IV. Cold sub-millimetre sources catalogue and statistical analysis. (2015)

Keywords : catalogs - submillimetre ISM - stars: formation - ISM: clouds

Abstract:For the project Galactic cold cores, Herschel photometric observations were carried out as a follow-up of cold regions of interstellar clouds previously identified with the Planck satellite. The aim of the project is to derive the physical properties of the population of cold sources and to study its connection to ongoing and future star formation. We build a catalogue of cold sources within the clouds in 116 fields observed with the Herschel PACS and SPIRE instruments. We wish to determine the general physical characteristics of the cold sources and to examine the correlations with their host cloud properties. ...(more)
Abstract: (hide)
The Galactic Cold Cores source catalogue contains the sub-millimetre sources extracted from the Herschel maps of the Galactic Cold Cores project using the extraction algorithm getsources. The source coordinates, size and orientations are provided along with the fluxes at 160, 250, 350 and 500 microns as computed by getsources. The physical properties (e.g. temperature, column density, mass, ...) derived from those observed properties are also provided. The table also gives the results of the classifications discussed in the paper (galactic or extragalactic source, starless or protostellar source).
