Long-slit optical spectroscopy of Large Magellanic Cloud radio supernova remnants
, 2008 We use long-slit spectra from shocked regions of radio supernova remnants (SNRs) in the Large Magellanic Cloud to estimate electron density and derive an average 'metal' abundance of 10-3.9 based on diagnostic line ratio plots.

MeerKAT 1.3 GHz Observations of Supernova Remnants
The Astrophysical Journal Supplement SeriesWe present full Stokes MeerKAT L -band (856–1712 MHz) observations of 36 high-latitude supernova remnants (SNRs). Sensitive, high-dynamic-range images show a wealth of structure. G15.1−1.6 appears to be a H ii region rather than an SNR.

The impact of the ambient gas density on the evolution of supernova remnants [PDF]
, 2018 This thesis presents a theoretical discussion of the full evolution of Supernova Remnants (SNRs), that includes the thermalization of the SN ejecta, the Sedov-Taylor and Snowplough stages of the SNR evolution.

Three-dimensional Velocity Diagnostics to Constrain the Type Ia Origin of Tycho's Supernova Remnant
The Astrophysical JournalWhile various methods have been proposed to disentangle the progenitor system for Type Ia supernovae, their origin is still unclear. A circumstellar environment is key to distinguishing between the double-degenerate and single-degenerate (SD) scenarios ...

Supernova Remnants in Gamma Rays
UniverseIn the 1960s, the remnants of supernova explosions (SNRs) were indicated as a possible source of galactic cosmic rays through the Diffusive Shock Acceleration (DSA) mechanism.

The origin of cosmic rays and TeV gamma-ray astronomy
EPJ Web of Conferences, 2013 Cosmic rays are accelerated to high energies in Galactic and extragalactic objects like Supernova remnants (SNR) and active galactic nuclei (AGN). How these accelerators work and how efficient they accelerate different types of particles to energies of ...

Magnetic Fields in Supernova Remnants
, 1976 Parkes 2 7 and 5 0 GHz polarization maps have been combined to obtain distributions of magnetic field, Faraday rotation and depolarization for 20 supernova remnants.

Using Polarised HI Absorption to Estimate Distances to Supernova Remnants
, 2021 Supernova remnants are the aftermath of the explosions of stars. In the study of Galactic supernova remnants, distance measurements are a vital supplement to astronomical observations.

An investigation of some contemporary problems in astronomy and astrophysics by way of early astronomical records [PDF]
, 1988 Early astronomical records of comets, supernovae, novae, sunspots and aurorae from Far Eastern dynastic histories together with records from Babylonians cuneiform tablets are compiled and analysed.
