Measurement of Anisotropies in Supernova Remnant Observations and Their Interpretation Using Numerical Models

The Astrophysical Journal
Supernova remnants (SNRs) exhibit varying degrees of anisotropy, which have been extensively modeled using numerical methods. We implement a technique to measure anisotropies in SNRs by calculating power spectra from their high-resolution images. To test

Time Evolution of the Synchrotron X-Ray Emission in Kepler’s Supernova Remnant: The Effects of Turbulence and Shock Velocity

The Astrophysical Journal
The maximum energy of electrons in supernova remnant (SNR) shocks is typically limited by radiative losses, where the synchrotron cooling time equals the acceleration time.

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 ...

Gamma-Ray Lines from Young Supernova Remnants [PDF]

, 1969
The gamma-ray luminosity of a typical type I supernova remnant has been calculated by assuming that the origin of the optical luminosity is due to the energy of the radioactive decay of Ni56.

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

Infrared studies of supernova remnants with the IRAS [PDF]

, 1986
A comparative study of the infrared and X-ray fluxes and morphologies of supernova remnants (SNR) can yield valuable information on their evolution and on their interaction with the smbient interstellar medium (ISM)
