Supernova remnants are among the most valuable astrophysical laboratory to study numerous physical processes involved in their evolution and interaction with the surrounding interstellar medium. These objects are one of ...

Emission line intensities from ionized nebulae are an important information source about this objects. There are many data on line intensities emitted from supernova remnants scattered in the literature. However, these ...

In this paper we briefly comment on the observational status of the possible physical association between unidentified EGRET sources and supernova remnants (SNRs) in our Galaxy. We draw upon recent results presented in the ...

The explosion of a supernovae (SN) represents the sudden injection of about 10^51 ergs of thermal and mechanical energy in a small region of space, causing the formation of powerful shock waves that propagate through the ...

The explosion of a supernova releases almost instantaneously about 10^51ergs of mechanic energy, changing irreversibly the physical and chemical proper- ties of large regions in the galaxies. The stellar ejecta, the nebula ...

We report on the discovery of a shell-type supernova remnant in the southern sky. It is a large (∼8◦×8◦), low-brightness source with a nonthermal radio spectrum, which requires background filtering to isolate it from the ...

Supernova Remnants (SNRs) are believed to be the main source of Galactic cosmic rays (CR). The strong SNR shocks provide ideal acceleration sites for particles of at least ∼ 1014 eV/nucleon. Radio continuum studies of SNRs ...

It might be thought that supernova remnants (SNRs) more distant than a few kiloparsec from Earth could not have been detected by the high-energy c-ray experiment EGRET on board of NASA s Compton Gamma-Ray Observatory. This ...

We performed three-dimensional magnetohydrodynamic simulations to study the evolution of a supernova remnant (SNR) in a turbulent neutral atomic interstellar medium. The media used as background shares characteristics with ...
