The bubble-like interior of the core-collapse supernova remnant Cassiopeia A [PDF]
Science, 2015 Burbling explosions blow metallic bubbles Stars more than about eight times the mass of the Sun don't go out quietly. Asymmetric explosions are kicked off by the collapse of their iron cores when no more fusion energy can sustain them.

RX-J0852−4622: THE NEAREST HISTORICAL SUPERNOVA REMNANT – AGAIN
Acta Polytechnica, 2013 RX-J0852−4622, a supernova remnant, is demonstrated to be closer than 500 pc, based on the measurements of the angular radius, the angular expansion rate and the TeV g-ray flux.

Nonthermal Radiation from Supernova Remnant Shocks [PDF]
Journal of Astronomy and Space Sciences, 2013 Most of high energy cosmic rays (CRs) are thought to be produced by diffusive shock acceleration (DSA) at supernova remnants (SNRs) within the Galaxy.

Searching for New Supernova Remnant Candidates from the VTSS Survey
Cumhuriyet Science Journal, 2022 The Virginia Tech Spectral Line Survey (VTSS) Galactic Plane Hydrogen-Alpha Survey has the strong ability to search and discover many different types of objects that cannot be identified clearly on red plates and by other Multi-Wavelength Sky Surveys ...

Supernova remnant W44: a case of cosmic-ray reacceleration [PDF]
, 2016 Supernova remnants (SNRs) are thought to be the primary sources of Galactic cosmic rays (CRs). In the last few years, the wealth of γ -ray data collected by GeV and TeV instruments has provided important information about particle energization in these ...

The Large Magellanic Cloud Supernova Remnant MCSNR J0550-6823
The Astrophysical Journal, 2023 We describe radio, optical, and X-ray observations of this rather faint, old Large Magellanic Cloud (LMC) supernova remnant. The [O iii ] emission forms a distinct shell, the remnant of the outer shock, which encloses the radio and X-ray emission and ...

An unusual white dwarf star may be a surviving remnant of a subluminous Type Ia supernova [PDF]
Science, 2017 Unusual star may be supernova debris Type Ia supernovae occur when a white dwarf star is completely destroyed in a thermonuclear explosion. Recently, another class of supernova has been found, dubbed type Iax; these look like type Ia but are much fainter

THE FIRST FERMI LAT SUPERNOVA REMNANT CATALOG [PDF]
, 2015 To uniformly determine the properties of supernova remnants (SNRs) at high energies, we have developed the first systematic survey at energies from 1 to 100 GeV using data from the Fermi Large Area Telescope (LAT). Based on the spatial overlap of sources

Nonthermal X-ray emission from young Supernova Remnants [PDF]
, 2000 The cosmic-ray spectrum up to the knee ($E\sim 10^{15}$ eV) is attributed to acceleration processes taking place at the blastwaves which bound supernova remnants. Theoretical predictions give a similar estimate for the maximum energy which can be reached

DESTRUCTION OF INTERSTELLAR DUST IN EVOLVING SUPERNOVA REMNANT SHOCK WAVES [PDF]
, 2015 Supernova generated shock waves are responsible for most of the destruction of dust grains in the interstellar medium (ISM). Calculations of the dust destruction timescale have so far been carried out using plane parallel steady shocks, however, that ...
