Nonthermal Radiation from Supernova Remnant Shocks [PDF]
Most of high energy cosmic rays (CRs) are thought to be produced by diffusive shock acceleration (DSA) at supernova remnants (SNRs) within the Galaxy.

Supernova remnant W44: a case of cosmic-ray reacceleration [PDF]
Supernova remnants (SNRs) are thought to be the primary sources of Galactic cosmic rays (CRs). In the last few years, the wealth of γ -ray data collected by GeV and TeV instruments has provided important information about particle energization in these ...

RX-J0852−4622: THE NEAREST HISTORICAL SUPERNOVA REMNANT – AGAIN
RX-J0852−4622, a supernova remnant, is demonstrated to be closer than 500 pc, based on the measurements of the angular radius, the angular expansion rate and the TeV g-ray flux.

Doppler Broadening and Line-of-sight Effects in Core-collapse Supernovae and Young Remnants
The dynamics and spectral characteristics of supernova ejecta reveal details of the supernova energetics, explosive nucleosynthesis, and evolution of the progenitor.

A CHANDRASEKHAR MASS PROGENITOR FOR THE TYPE Ia SUPERNOVA REMNANT 3C 397 FROM THE ENHANCED ABUNDANCES OF NICKEL AND MANGANESE [PDF]
Despite decades of intense efforts, many fundamental aspects of Type Ia supernovae (SNe Ia) remain elusive. One of the major open questions is whether the mass of an exploding white dwarf (WD) is close to the Chandrasekhar limit.

An unusual white dwarf star may be a surviving remnant of a subluminous Type Ia supernova [PDF]
Unusual star may be supernova debris Type Ia supernovae occur when a white dwarf star is completely destroyed in a thermonuclear explosion. Recently, another class of supernova has been found, dubbed type Iax; these look like type Ia but are much fainter

The Large Magellanic Cloud Supernova Remnant MCSNR J0550-6823
We describe radio, optical, and X-ray observations of this rather faint, old Large Magellanic Cloud (LMC) supernova remnant. The [O iii ] emission forms a distinct shell, the remnant of the outer shock, which encloses the radio and X-ray emission and ...

THE FIRST FERMI LAT SUPERNOVA REMNANT CATALOG [PDF]
To uniformly determine the properties of supernova remnants (SNRs) at high energies, we have developed the first systematic survey at energies from 1 to 100 GeV using data from the Fermi Large Area Telescope (LAT). Based on the spatial overlap of sources

DESTRUCTION OF INTERSTELLAR DUST IN EVOLVING SUPERNOVA REMNANT SHOCK WAVES [PDF]
Supernova generated shock waves are responsible for most of the destruction of dust grains in the interstellar medium (ISM). Calculations of the dust destruction timescale have so far been carried out using plane parallel steady shocks, however, that ...
