A Statistical Analysis of Galactic Radio Supernova Remnants
The Astrophysical Journal Supplement Series, 2023 We present a revised table of 390 Galactic radio supernova remnants (SNRs) and their basic parameters. Statistical analyses are performed on SNR diameters, ages, spectral indices, Galactic heights, and spherical symmetries.

EMU Detection of a Large and Low Surface Brightness Galactic SNR G288.8–6.3
The Astronomical Journal, 2023 We present the serendipitous detection of a new Galactic supernova remnant (SNR), G288.8–6.3, using data from the Australian Square Kilometre Array Pathfinder (ASKAP) Evolutionary Map of the Universe (EMU) survey.

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 ...

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

The Effects of Elemental Abundances on Fitting Supernova Remnant Models to Data
Universe, 2022 Models for supernova remnant (SNR) evolution can be used to determine the energy of the explosion, the age of the SNR, and the density of the surrounding medium by matching observations. Observed SNR properties derived from the X-ray spectrum include the

The Astrophysical Journal, 2023 The nature of Type Ia supernovae remains controversial. The youngest remnants of Ia supernovae hold clues to the explosion and to the immediate surroundings. We present a third epoch of Chandra observations of the ∼600 yr old Type Ia remnant 0519–69.0 in

Multiple-supernova remnants [PDF]
International Astronomical Union Colloquium, 1989 ABSTRACTThe present observational and theoretical status of multiple-supernova remnants is briefly reviewed, and evolutionary models of the remnants around OB associations are presented. The remnants are followed for up to almost 30 Myr in various galactic environments (Gaussian or composite disks combined with cold or hot halos).
