Abstract:
Methanol masers are often detected in regions of intense star
formation. Several studies in the last decade indicate that they may
even be the earliest signpost of a high-mass star-forming region.
Their powerful emission makes them very good candidates for
observations using both single-dish telescopes and interferometers,
the latter allows detailed structural and dynamical
study of these objects. We present here a catalogue of all known
6.7GHz methanol masers, discovered both by surveys that targeted
possible associated objects and unbiased surveys covering a large
fraction of galactic longitudes across the Galactic plane
0.5°≤b≤0.5deg for most of the regions). The 519 sources which
are listed with their kinematic (galactocentric and heliocentric)
distance as well as possibly associated IR objects. We find that
6.7GHz methanol masers clearly trace the molecular ring of our Galaxy,
where most of the OB associations are located. The present list of
masers also reports detections of other masing transitions of methanol
as further information for the study of the maser phenomenon. In a
further publication we will address some statistical considerations.
Description:
The catalogue of the 6.7GHz methanol masers comprises all detected
sources since the discovery of this intense radiation. For every
source we report name, right ascension and declination in J2000,
galactic coordinates, vlsr, velocity range, peak flux, galactocentric
and heliocentric distances (near and far), IRAS and MSX associations
if any, usual name, detected methanol masers at 12, 44, 85.5, 86.5,
95, 107, 108, 156GHz, reference of the 6.7GHz detection and
reobservation.
