1410 MHz continuum and HI line observations towards the SNR G 296.5+10.0 and nearby sources. Evidences of two SNRs tunneling through the interstellar medium.
Abstract
1410 MHz radio continuum and H I 21 cm line observations have been performed on an extended area that contains the SNR G296.5+10.0. Two additional radio-continuum sources have been identified in the 1410 MHz map, namely (1) G300.1+9.4, which is classified as a faint SNR, located at a distance comparable to that of G296.5+10.0, and (2) G300.8+11.7, with a broken spectrum and a possible double structure unresolvable with the present resolution. The observations reproduce the theoretically expected outcome of two interacting supernova remnants. In addition, some small H I clouds accelerated to relatively high velocities are observed to be positionally coincident with the SNRs.
