Celebrating the life of Jim Caswell |
Tribute by Tim Bedding (School of Physics, University of Sydney) |
Tim writes "Everyone remembers their first
paper. Mine was
Caswell, Kesteven, Bedding & Turtle (1989). Jim was kind enough to include
me, a mere third-year student who had made a modest contribution during a
winter school at Molonglo Observatory (shown above). I've always remembered his generous approach
and tried to emulate it ever since. A wonderful man." Caswell et al. 1989: G357.7-0.1 - A double-lobed radio source? The radio source G357.7-0.1 has commonly been regarded as a galactic supernova remnant; alternative interpretations have concentrated on the pronounced brightness gradient along its major axis. Analysis of a new map shows that this brightness gradient masks an even more crucial characteristic - symmetry about the center - the key to a totally different interpretation. |
