Radio Constraints on the Circumstellar Environment of the Type IIb Supernova SN 2024iss
Yuhei Iwata, Tomoki Matsuoka, Masanori Akimoto +6
Type~IIb supernovae exhibit diverse progenitor properties, and radio observations offer a unique probe of their mass-loss histories shortly before the explosion. We present Japanes…
Shock breakout from mildly relativistic ejecta in a dense wind: the case of EP260321a/SN 2026gzf
Akihiro Suzuki, Keiichi Maeda, Toshikazu Shigeyama
We present shock breakout (SBO) modeling of the recently discovered X-ray transient EP260321a detected by the \textit{Einstein Probe} mission. Our semi-analytic model, based on our…
Radio and X-ray Observations of the Transitional Supernova 2019yvr: Insights into the Progenitor Mass-Loss History
Raphael Baer-way, Raphael Baer-Way, Poonam Chandra +8
The final life stages of the massive star progenitors of stripped-envelope supernovae (SESNe) are still an open question, especially when it comes to the timing and magnitude of th…
VLBI Astrometry of Magnetars
Takuya Akahori, Sujin Eie, Kei Amada +8
The origin of the strongest magnetic fields in the Universe, i.e., the origin of magnetars, is a longstanding question. An enhanced dynamo effect in an irregular supernova explosio…
