Supernova remnants (SNRs) are a complex class of sources, and their heterogeneous nature has
hindered the characterization of their general observational properties. To overcome this challenge,in thi...
Spitzer observations of supernova remnants: II. Physical conditions and comparison with HH7 and HH54

We have studied the shock-excited molecular regions associated with four supernova remnants (SNRs) — IC443C, W28, W44 and 3C391 — and two Herbig-Haro objects,HH7 and HH54, using Spitzer ’s Infrared Sp...

The Fermi $\gamma$-ray space telescope reported the observation of several Galactic supernova remnants recently, with the $\gamma$-ray spectra well described by hadronic $pp$ collisions. The possible ...
MULTIFREQUENCY OBSERVATIONS OF ONE OF THE LARGEST SUPERNOVA REMNANTS IN THE LOCAL GROUP OF GALAXIES, LMC - SNR J0450-709

2009/3/13
In this preliminary report a modification of the theoretical Σ − D
relation for supernova remnants (SNRs) in the adiabatic expansion phase is presented
in another way. As in Paper I, this modi...
A MODIFIED THEORETICAL Sigma-D RELATION FOR SUPERNOVA REMNANTS：I. THE CASE OF CONSTANT TEMPERATURE WITHIN THE SUPERNOVA REMNANT
ISM supernova remnants-radiation mechanisms thermal-radio continuum ISM
2009/3/13
We present a modification of the theoretical Σ − D relation for
supernova remnants (SNRs) in the adiabatic expansion phase. This modification
is based on the convolution of the relation first ...

We have collected all the available data on Galactic supernova
remnants given in the literature. The data of Galactic supernova remnants located
in the Galactic longitude interval l=90{270 in all ...
