Shock Wave Precursors in M33 Supernova Remnants

The Astrophysical Journal
We present high-resolution profiles of the H α , [N II ], and [O III ] lines of supernova remnants (SNRs) in M33. The 8 km s ^−1 resolution allows us to separate emission from the photoionized shock precursors from the emission from shocked gas.

Regions of Suppressed Diffusion around Supernova Remnants?

The Astrophysical Journal
The recent discovery of the so-called TeV halos has attracted much attention. The morphology of the emission requires that the region is characterized by severe suppression of the diffusion coefficient. This finding raises many questions as to its origin:

X-ray spectra of supernova remnants [PDF]

, 1985
X-ray spectra were obtained from fields in three supernova remnants with the solid state spectrometer of the HEAO 2 satellite. These spectra, which contain lines from K-shell transitions of several abundant elements with atomic numbers between 10 and 22,

Single versus Binary Origin: The Diversity of Stripped-envelope Supernova Remnants

The Astrophysical Journal
Core-collapse supernova remnants (CCSNRs) are crucial for understanding the final stages of massive star evolution, as they reflect the imprints of their progenitors’ preexplosion activities.
