Supernova Remnants with Fermi Large Area Telescope

EPJ Web of Conferences, 2017
The Large Area Telescope (LAT), on-board the Fermi satellite, proved to be, after 8 years of data taking, an excellent instrument to detect and observe Supernova Remnants (SNRs) in a range of energies running from few hundred MeV up to few hundred GeV ...

X-ray Polarimetry of Supernova Remnants

, 2021
Young supernova remnants such as Tycho, Cas A and SN1006 are relativistic particle accelerators and likely the sources of Galactic cosmic rays. In these sources X-ray synchrotron emitting regions, such as the shock fronts, have been identified and their ...

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

Searching for runaway OB stars in Supernova remnants

, 2005
Searching for runaway stars in Supernova remnants gives us the possibility to estimate the mass ratio in binary systems in which there occur Supernova explosion.

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

CO emission from supernova remnants [PDF]

, 1977
In a search for molecular gas associated with supernova remnants, the CO line has been observed in three optical remnants: the Cygnus Loop, IC 443, and Cas A. In both the Cygnus Loop and IC 443, CO molecules are detected from dense clouds of the order of

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.

Radio Emission from 16 Possible Supernova Remnants

, 1969
Sixteen radio sources, thought to be supernova remnants, have been observed at several frequencies between 408 and 2700 MHz. These data, together with previously published observations, have been used to derive spectra for these sources.
