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:

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.

Revisiting the Supernova Engines in the 3C 397 and W49B Supernova Remnants

The Astrophysical Journal
The nature of the supernova remnants (SNRs) 3C 397 and W49B has long been a subject of debate, with prior studies offering conflicting interpretations between thermonuclear and core-collapse scenarios. To help settle this debate, we present a systematic,

Evolution of Supernova Remnants. 1. Interacting Supernova Remnants

Evolution of Supernova Remnants. 1. Interacting Supernova Remnants
application/pdf The evolution and structure of two interacting supernova remnants (SNRS) are calculated by use of a timedependent two-dimensional hydro- dynamic code. The interactions of two SNRs are simulated in such a Way that at a time t。 after the first supernova explosion, the second Supernova explosion occurs at the distance D and two SNRs ...
