Bell Instability–mediated Diffusive Shock Acceleration at Supernova Blast Wave Shock Propagating in the Interstellar Medium

The Astrophysical Journal
Supernova blast wave shock is a very important site of cosmic-ray acceleration. However, the detailed physical process of acceleration, in particular, nonlinear interplay between cosmic-ray streaming and magnetic field amplification, has not been studied

The evolution of mass loaded supernova remnants

, 2002
We describe the evolution of spherically symmetric supernova remnants in which mass addition takes place from embedded clouds. We derive simple approximations to the remnant evolution which can be used for investigating the generation of supernova ...

TeV gamma rays from supernova remnants

, 2012
International audienceSupernova remnants are believed to be the sources of galactic cosmic rays. As expected in this scenario, several of them have been indeed detected in TeV gamma rays.

Shock Wave Precursors in M33 Supernova Remnants

The Astrophysical Journal
We present high-resolution profiles of the H α , [N II ], and [O III ] lines of supernova remnants (SNRs) in M33. The 8 km s ^−1 resolution allows us to separate emission from the photoionized shock precursors from the emission from shocked gas.

Supernova remnants in M33

, 1978
A summary is given of optical observations and radio observations connected with the successful identification of three supernova remnants in M33. The optical observations also allow a discussion of element abundances, while the radio observations have ...

Supernova remnants and the origin of cosmic rays

, 2014
Supernova remnants have long been considered to be the dominant sources of Galactic cosmic rays. For a long time the prime evidence consisted of radio synchrotron radiation from supernova remnants, indicating the presence of electrons with energies of ...

Regions of Suppressed Diffusion around Supernova Remnants?

The Astrophysical Journal
The recent discovery of the so-called TeV halos has attracted much attention. The morphology of the emission requires that the region is characterized by severe suppression of the diffusion coefficient. This finding raises many questions as to its origin:
