Morphology of supernova remnants and their halos [PDF]
Astronomy & Astrophysics, 2021 Context. Supernova remnants (SNRs) are known to accelerate particles to relativistic energies, on account of their nonthermal emission. The observational progress from radio to gamma-ray observations reveals more and more morphological features that need to be accounted for when modeling the emission from those objects. Aims.

Supernova Remnants and their Supernovae [PDF]
International Astronomical Union Colloquium, 1988 AbstractObserving supernova remnants provides important clues to the nature of supernova explosions. Conversely, the late stages of stellar evolution and the mechanism of supernova explosions affect supernova remnants through circumstellar matter, stellar remnants, and nucleosynthesis. The elements of supernova classification and the connection between

Non-cosmological FRBs from young supernova remnant pulsars [PDF]
, 2015 We propose a new extra but non-cosmological explanation for fast radio bursts (FRBs) based on very young pulsars in supernova remnants. Within a few hundred years of a core-collapse supernova, the ejecta is confined within similar to 1 pc, providing a ...

Radiative Supernova Remnants and Supernova Feedback [PDF]
The Astrophysical Journal, 2020 Abstract Supernova (SN) explosions are a major feedback mechanism, regulating star formation in galaxies through their momentum input. We review the observations of SNRs in radiative stages in the Milky Way, to validate theoretical results regarding the momentum/energy injection from a single SN explosion.

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

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.

INTERSTELLAR AND EJECTA DUST IN THE CAS A SUPERNOVA REMNANT [PDF]
, 2014 Infrared continuum observations provide a means of investigating the physical composition of the dust in the ejecta and swept up medium of the Cas A supernova remnant (SNR). Using low-resolution Spitzer IRS spectra (5–35 μm), and broad-band Herschel PACS

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 ...
