Radio emission from interstellar shocks: Young type Ia supernova remnants and the case of N 103B in the Large Magellanic Cloud

Abstract

We investigate young type Ia supernova remnants (SNRs) in our Galaxy and neighbouring galaxies in order to understand their properties and early stage of their evolution. Here we present a radio continuum study based on new and archival data from the Australia Telescope Compact Array (ATCA) towards N 103B, a young (≤1000 yrs) spectro-This article belongs to the Topical Collection: Plasma, Particles, and Photons: ISM Physics Revisited.

An Expanding Shell of Neutral Hydrogen Associated with SN 1006: Hints for the Single-degenerate Origin and Faint Hadronic Gamma-Rays

“…The presence of a dense-gas wall and the SD scenario were also supported by the rapid shock deceleration during the last ∼15 yr (Tanaka et al 2021). Subsequent CO and H I studies found similar expanding shells of atomic and/or molecular clouds in the Type Ia SNRs: RCW 86 (Sano et al 2017), N103B (Sano et al 2018;Alsaberi et al 2019), and G344.7−0.1 (Fukushima et al 2020). To better understand the progenitor system of Type Ia supernovae, we need further observations of interstellar molecular and atomic clouds toward other Type Ia SNRs.…”

Editorial: Plasma, particles, and photons: ISM physics revisited

“…In this topical collection we collect reviews and new results in ISM research with an emphasis on multi-messenger Astrophysics. There are contributions on the production of cosmic ray (CR) electrons (Alsaberi et al 2019) and their transport (Heesen 2021) as deduced from observations, the generation of X-rays and cosmic γ -rays in interstellar shocks (Sano and Fukui 2021), the mechanism of particle acceleration via diffuse shock acceleration (Urošević et al 2019), the thermal and non-thermal X-ray emission from superbubbles (Kavanagh 2020), and the characteristics of non-equilibrium ionisation plasmas (Breitschwerdt and de Avillez 2021). Next, there are contributions on simulations of cosmic ray propagation (Mertsch 2020), on their detection (Albrecht et al 2022) and what we can learn from that, on interstellar radioactive isotopes (Diehl 2021), and on observations of neutrinos (Kheirandish 2020).…”

“…In particular, the interaction of the shock with cold and dense interstellar clouds is believed to lead to significant amplification of the interstellar magnetic fields and hence to strong emission from non-thermal particles (Sano and Fukui 2021). The emission of the thermal shocked plasma is detected in X-ray observations, while emission from non-thermal relativistic particles can be observed over the entire electromagnetic spectrum from radio (e.g., Alsaberi et al 2019) all the way up to TeV energies.…”
