Numerical code for fitting radial emission profile of a shell supernova remnant: Application [PDF]
Serbian Astronomical Journal, 2011 We present IDL (Interactive Data Language) codes for fitting a theoretical emission profile of a shell supernova remnant (SNR) to the mean profile of an SNR obtained from radio observations. Two considered theoretical models are: 1) a shell with

A long-period, violently-variable X-ray source in a young SNR [PDF]
, 2006 Observations with the Newton X-ray Multimirror Mission (XMM) show a strong periodic modulation at 6.67+/-0.03 hours of the X-ray source at the centre of the 2,000-year-old supernova remnant RCW 103. No fast pulsations are visible.

Examining Neutrino–Matter Interactions in the Cassiopeia A Supernova
The Astrophysical Journal, 2023 Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confirm observationally.

The many sides of RCW 86: a type Ia supernova remnant evolving in its progenitor's wind bubble [PDF]
, 2014 We present the results of a detailed investigation of the Galactic supernova remnant RCW 86 using the XMM-Newton X-ray telescope. RCW 86 is the probable remnant of SN 185 A.D, a supernova that likely exploded inside a wind-blown cavity.

Magnetohydrodynamic Simulations of the Supernova Remnant G1.9+0.3
The Astrophysical Journal, 2023 The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the north, while the X-ray observation shows two opposite “ears” on the east ...

Gamma-ray emission from young supernova remnants: Hadronic or leptonic?
EPJ Web of Conferences, 2016 The debate on the nature of the gamma-ray emission from young supernova remnants is still open. Ascribing such emission to hadronic rather than leptonic processes would provide an evidence for the acceleration of protons and nuclei, and this fact would ...

What Produced the Ultraluminous Supernova Remnant in NGC 6946? [PDF]
, 1999 The ultraluminous supernova remnant (SNR) in NGC 6946 is the brightest known SNR in X-rays, ~1000 times brighter than Cas A. To probe the nature of this remnant and its progenitor, we have obtained high-dispersion optical echelle spectra.

On the nature of Tycho Brahe’s supernova
Frontiers in Astronomy and Space Sciences, 2023 At the 450 years anniversary of its observation, the supernova named after Tycho Brahe, SN 1572, can be explained in the terms used nowadays to characterize Type Ia supernovae (SNe Ia).

Generation of Cosmic rays in Historical Supernova Remnants
EPJ Web of Conferences, 2013 We present the results of observations of two types of Galactic supernova remnants with the SHALON mirror Cherenkov telescope of Tien-Shan high-mountain Observatory: the shell-type supernova remnants Tycho, Cas A and IC 443; plerions Crab Nebula, 3c58 ...
