Galactic Supernova Remnants: From radio frequencies to TeV
(Asociacion Argentina de Astronomia, 2007-09)
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 ...
Status of the Connection between Unidentified Egret Sources and Supernova Remnants: The Case of Cta 1
(Springer, 2004-06)
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 ...
Radio emission from Supernova Remnants
(Springer, 2015-09-16)
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 ...
Detection of a new, low-brightness supernova remnant possibly associated with EGRET sources
(EDP Sciences, 2001-02)
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 ...
Radio observations of supernova remnants and the surrounding molecular gas
(Societa Astronomica Italiana, 2011-01)
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 ...
Did EGRET detect distant supernova remnants?
(Elsevier, 2004-12)
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 ...
Supernova remnants and γ-ray sources
(Elsevier Science, 2003-08)
A review of the possible relationship between gamma-ray sources and supernova remnants (SNRs) is presented. Particular emphasis is given to the analysis of the observational status of the problem of cosmic ray acceleration ...
An X-ray study of the supernova remnant G20.0-0.2 and its surroundings
(Edp Sciences, 2013-06)
Aims. We study the supernova remnant G20.0-0.2 and its surroundings in order to look for the high energy counterpart of the radio nebula and to find evidence of interaction between the shock front and the interstellar ...
The supernova remnant CTB 37B and its associated magnetar CXOU J171405.7-381031: evidence for a magnetar-driven remnant
(NATL ASTRONOMICAL OBSERVATORIES, CHIN ACAD SCIENCES, 2011)
We discuss the association between the candidate magnetar CXOU J171405.7-381031 and the supernova remnant CTB 37B. The recent detection of the period derivative of the object allowed an estimation of a young characteristic ...
A 3D numerical model for Kepler's supernova remnant
(Oxford University Press, 2014-05)
We present new 3D numerical simulations for Kepler´s supernova remnant. In this work we revisit the possibility that the asymmetric shape of the remnant in X-rays is the product of a type Ia supernova explosion which occurs ...
