Abstract

We present a high-resolution radio-continuum study of Galactic supernova remnant MSH 11-61A. We combine moderate resolution X-ray, radio-continuum and CO data to study the morphology and kinematics of MSH 11-61A. We estimate the radio-continuum spectral index to be ∞843-4850=-0.33 ±0.07 based on our flux density measurements and also note that this SNR has signi cant `turn-over' spectra at lower (29.9-843 MHz) frequencies. The diameter of MSH11{61A is estimated to be 12.5' with 'ear' extensions of 4' to the northwest and southeast. The striking anticorrelation between X-ray and radio-continuum images con rms a mixed-morphology classi cation of this remnant. The CO images are consistent with a distance reported by Rosado et al. (1996) of about 7 kpc.
