Neutral hydrogen in the vicinity of galactic radio sources: the supernova remnant W44

OSTI ID:5281511
The H I radio line has been observed in absorption and emission near the source W44 with the RATAN-600 radio telescope at 2'.2 x 20' x 6.3 km/sec resolution. The absorption-line observations show that the nearby H II region NRAO 584 cannot be physically associated with the supernova remnant. The six H I clouds detected in emission and absorption may possibly form part of a patchy envelope around W44; three of them coincide with a molecular cloud in the vicinity. The combined mass of the H I clouds is roughly-equal220 M/sub sun/, and if the envelope is real it would be expanding at roughly-equal10 km/sec. Estimates are obtained for the age of the supernova remnant and the physical parameters of NRAO 584.
