Probing the Dispersion and Rotation Measure Contributions from Supernova Remnants in Fast Radio Burst Source Environments with 1D SNR Simulation
Zhao Joseph Zhang, Gaku Kawashima, Shiu-Hang Lee +3
Fast radio bursts (FRBs) provide a sensitive probe of ionized baryons through their dispersion measure (DM). In addition to slowly evolving cosmological terms, at least two repeate…
Single vs. Binary Origin: The Diversity of Stripped-Envelope Supernova Remnants
Gaku Kawashima, Shiu-Hang Lee, Keiichi Maeda +1
Core-collapse supernova remnants (CCSNRs) are crucial for understanding the final stages of massive star evolution, as they reflect the imprints of their progenitors' pre-explosion…
Cosmic-Ray Bath in a Past Supernova Gives Birth to Earth-Like Planets
Ryo Sawada, Hiroyuki Kurokawa, Yudai Suwa +3
A key question in astronomy is how ubiquitous Earth-like rocky planets are. The formation of terrestrial planets in our solar system was strongly influenced by the radioactive deca…
Exploring the circumstellar environment of Tycho's supernova remnant. II. Impact on the broadband non-thermal emission
Ryosuke Kobashi, Shiu-Hang Lee, Takaaki Tanaka +1
While the environment around Tycho's supernova remnant (SNR) has long been believed to be close to homogeneous, the latest analysis of Chandra data has identified a substantial dec…
