Magneto-hydrodynamical simulation with cosmic ray acceleration at supernova remnants. [PDF]

, 2020
Supernova remnants shocks are considered the best sites for the production of Galactic cosmic rays. The interactions of cosmic rays produced at supernova shocks with photon fields and the interstellar medium generate a multi-wavelength spectrum from ...

X-Ray Emission Properties of Supernova Remnants

, 2016
X-ray emission from supernova remnants can be broadly divided into thermal X-ray emission from the shock-heated plasmas and in nonthermal (synchrotron) emission caused by very high-energy (10–100 TeV) electrons moving in the magnetic fields of the hot ...

Mixing of materials in magnetised core-collapse supernova remnants

, 2023
Core-collapse supernova remnants are structures of the interstellar medium (ISM) left behind the explosive death of most massive stars (smaller or equal to 40 Mo).

OBSERVATIONS OF NON TYPICAL MASERS AT THE RT-22 RADIO TELESCOPE IN 2004–2013

Radio Physics and Radio Astronomy, 2017
Purpose: Some peculiarities of emission of Class I methanol masers on the 80–71A+ transition at 95 GHz in sources closely associated with protostar-forming regions and in supernova remnants are studied.

Missing Supernova Remnants

, 1980
The discrepancy between supernova explosion rates estimated from statistics of pulsars and of supernova remnants (SNRs) is well conciliated, if we consider that a considerable fraction of SNRs is missing.

INTERACTION OF SUPERNOVA BLAST WAVES WITH WIND-DRIVEN SHELLS: FORMATION OF

Odessa Astronomical Publications, 2017
Most of middle-aged supernova remnants (SNRs) have a distorted and complicated appearance which cannot be explained in the framework of the Sedov-Taylor model.

Neutrino emission of Fermi supernova remnants

, 2011
The Fermi gamma-ray space telescope reported the observation of several Galactic supernova remnants recently, with the gamma-ray spectra well described by hadronic pp collisions.

Revisiting γ-Ray Emission of the Supernova Remnant RCW 103

The Astrophysical Journal
We analyze more than 15 yr of γ -ray data obtained with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi) for the region of the young supernova remnant (SNR) RCW 103, since the nearby source 4FGL J1616.2−5054e ...

Positron Annihilation Spectroscopy of Young Supernova Remnants

Odessa Astronomical Publications, 2018
This paper discusses radiative and thermodynamic properties of cold rarefied aggregates of non-uniformly distributed gas and dust through which high fluxes of positrons with energies of 0.011-3.6 MeV pass.

Distribution of Supernova Remnants in the Galaxy

, 2020
The number of Supernova Remnants (SNRs) observable in the Galaxy is consistent with the number expected to be formed in a Universe that is 7,000 years old.
