The Radio Signatures of the First Supernovae
, 2013 Primordial stars are key to primeval structure formation as the first stellar components of primeval galaxies, the sources of cosmic chemical enrichment and likely cosmic reionization, and they possibly gave rise to the supermassive black holes residing ...

ARE MODELS FOR CORE-COLLAPSE SUPERNOVA PROGENITORS CONSISTENT WITH THE PROPERTIES OF SUPERNOVA REMNANTS? [PDF]
, 2015 The recent discovery that the Fe–K line luminosities and energy centroids observed in nearby supernova remnants are a strong discriminant of both progenitor type and circumstellar environment has implications for our understanding of supernova progenitor

Multifrequency observations of one of the largest supernova remnants in the local group of galaxies, LMC - SNR J0450-709 [PDF]
Serbian Astronomical Journal, 2009 We present the results of new Australia Telescope Compact Array (ATCA) observations of one of the largest supernova remnants, SNR J0450-709, in the Local Group of galaxies.

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 ...

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 ...

Multi-Wavelength View of Supernova Remnants
Acta Polytechnica CTU Proceedings, 2014 This contribution gives a very short overview on the emission of supernova remnants and the processes that are responsible for both the thermal and non-thermal origins of the emission, typically observed in radio, X-rays, and up to gamma-rays. We discuss

Particle propagation in clumpy supernova remnants [PDF]
EPJ Web of Conferences, 2019 The presence of dense clumps in the environment where a supernova remnant expands might have a strong impact in shaping the observed hadronic gamma-ray spectrum.

OH Masers and Supernova Remnants [PDF]
, 2012 OH(1720 MHz) masers are created by the interaction of supernova remnants with molecular clouds. These masers are pumped by collisions in warm, shocked molecular gas with OH column densities in the range 10^{16}--10^{17} cm^{-2}.
