A 20-yr radio light curve for the young supernova remnant G1.9+0.3
Abstract The radio source G1.9+0.3 has recently been identified as the youngest known Galactic supernova remnant, with a putative age of ∼100 yr. We present a radio light curve for G1.9+0.3 based on 25 epochs of observation with the Molonglo Observatory Synthesis Telescope, spanning 20 yr from 1988 to 2007. …
