GLOSTAR GPS. 6.7GHz Methanol Maser Catalogue

Listed in IVOA Registry (Virtual Observatory)

Class II methanol (CH_3_OH) masers are amongst the clearest signposts of recent high-mass star formation (HMSF).

Description

A complete catalogue outlines the distribution of star formation in the Galaxy, the number of young star-forming cores, and the physical conditions of their environment, made possible by the Global View on Star Formation (GLOSTAR) survey. This blind survey of the radio regime of 4-8GHz maps the Galactic mid-plane in the radio continuum, 6.7GHz methanol line, the 4.8 GHz formaldehyde line, and several radio recombination lines.

We present an analysis of the observations of the 6.7GHz CH_3_OH maser transition using data from the D-configuration of the Very Large Array (VLA). We analysed data covering Galactic longitudes from -2{deg}<l<60{deg} and Galactic latitudes of |b|<1{deg}. We detected a total of 554 methanol masers, out of which 84 are new, and we catalogued their positions, velocity components, and integrated fluxes.

With a typical noise level of ~18mJy/beam, this is the most sensitive unbiased methanol survey for methanol masers to date. We also searched for dust continuum and radio continuum associations, finding that 97% of the sources are associated with dust and 12% are associated with radio continuum emission.
