Multimessengers from Core-Collapse Supernovae: Multidimensionality as a Key to Bridge Theory and Observation by Kei Kotake, Tomoya Takiwaki, Yudai Suwa, Wakana Iwakami Nakano, Shio Kawagoe, Youhei Masada, Shin-ichiro Fujimoto

“…Core-collapse supernovae are dramatic explosions marking the catastrophic end of massive stars. The only means to get direct information about the supernova engine is from observations of neutrinos emitted by the forming neutron star, and through gravitational waves which are produced when the hydrodynamic flow or the neutrino flux is not perfectly spherically symmetric. …”

Insights into the Properties of Type Ibn/Icn Supernovae and Their Progenitor Channels through X-Ray Emission by Yusuke Inoue, Keiichi Maeda

“…Type Ibn/Icn supernovae (SNe Ibn/Icn), which are characterized by narrow helium or carbon lines that originated in hydrogen-poor dense circumstellar medium (CSM), provide new insights into the final evolution of massive stars. While SNe Ibn/Icn are expected to emit strong X-rays through the strong supernova (SN)-CSM interaction, the X-ray emission modeling effort has been limited so far. …”
