An atomic and molecular study of the interstellar medium around the supernova remnant RCW 103

We report on the detection of HCO? and 12CO emission in the rotational transition J ? 1?0 in the vicinity of the shock front at the southern border of the supernova remnant RCW 103, where previous infrared observations suggest an interaction with a molecular cloud. The observations were carried out...
