Light Curve Modeling of Superluminous Supernova 2006gy: Collision between Supernova Ejecta and Dense Circumstellar Medium
Takashi J. Moriya, Sergei I. Blinnikov, Nozomu Tominaga +4
We show model light curves of superluminous supernova 2006gy on the assumption that the supernova is powered by the collision of supernova ejecta and its dense circumstellar medium…
Progenitors of Recombining Supernova Remnants
Takashi J. Moriya
Usual supernova remnants have either ionizing plasma or plasma in collisional ionization equilibrium, i.e., the ionization temperature is lower than or equal to the electron temper…
A Dip after the Early Emission of Super-Luminous Supernovae: A Signature of Shock Breakout within Dense Circumstellar Media
Takashi J. Moriya, Keiichi Maeda
The origin of super-luminous supernovae (SLSNe), especially the source of their huge luminosities, has not been clarified yet. While a strong interaction between SN ejecta and dens…
Detectability of High-Redshift Superluminous Supernovae with Upcoming Optical and Near-Infrared Surveys
Masaomi Tanaka, Takashi J. Moriya, Naoki Yoshida +1
Observations of high-redshift supernovae (SNe) open a novel opportunity to study the massive star population in the early Universe. We study the detectability of superluminous SNe…
