Evidence of X-ray emission from W44.
Abstract
The Astronomical Netherlands Satellite (ANS) has provided X-ray observations around the supernova remnant W44. X-ray emission with an observed intensity of 8 x 10 to the -11th power erg/sq cm/s (i.e., 1.03-3.5 keV) has been detected from a region which overlaps the radio source. Spectral fits to the pulse-height data and the application of the shock-wave model for the evolution of the signal-to-noise ratio suggest that W44 is the X-ray source.
