Bozzetto et al. present a new ASKAP
sample of 14 radio supernova remnants (SNR) candidates in the Large
Magellanic Cloud (LMC). This new sample is a significant increase to
the known number of older, larger, and low surface brightness LMC
SNRs. A multi-frequency study was made for each object and
possible traces of optical and occasionally X-ray emission found in several
of the candidates.
The plot above shows the distribution of the diameters of the
14 new LMC SNR candidate (orange) added to the 71 previously known SNRs (blue).
A diameter of 50 parsecs corresponds to just over 160 light years.
The diameter of the Earth's orbit is 16.6 light minutes, and
the diameter of Pluto's orbit is about 11 light hours,
and the nearest star to our Sun is about 4.4 light years away -- putting
the size of these supernova remnants into perspective!
