Dave Green's research: G1.9+0.3

G1.9+0.3 has been recently identified as the youngest known Galactic supernova remnant, see:

Below a 4.86-GHz image of G1.9+0.3 from observations made in 2008 is compared with a matched-resolution 1.49-GHz image from observations made in 1985 (move cursor on/off).

G1.9+0.3 at 4.86 GHz from 2008-Mar-12 and at 1.49 GHz from 1985-Apr-16 (when cursor over).

Here are:

• the entry for G1.9+0.3 from my Galactic supernova remnant catalogue, which contains links to earlier papers which include observations of this SNR;
• a query centred on G1.9+0.3 from Simbad.
