High resolution HI and radio continuum observations of the SNR G290.1-0.8

Abstract

We have observed the supernova remnant (SNR) G290.1-0.8 in the 21-cm HI line and the 20-cm radio continuum using the Australia Telescope Compact Array (ATCA). The HI data were combined with data from the Southern Galactic Plane Survey to recover the shortest spatial frequencies. In contrast, HI absorption was analyzed by filtering extended HI emission, with spatial frequencies shorter than 1.1 k-lambda. The low-resolution ATCA radio continuum image of the remnant shows considerable internal structure, resembling a network of filaments across its 13 arcmin diameter. A high-resolution ATCA radio continuum image was also constructed to study the small scale structure in the SNR. It shows that there are no structures smaller than ~17", except perhaps for a bright knot to the south, which is probably an unrelated object. The HI absorption study shows that the gas distribution and kinematics in front of SNR G290.1-0.8 are complex. We estimate that the SNR probably lies in the Carina arm, at a distance 7 (+/- 1) kpc. In addition, we have studied nearby sources in the observed field using archival multiwavelength data to determine their characteristics.
