Light curve modeling of fast-evolving supernova KSN 2015K: explosion in circumstellar matter of Super-AGB progentor
Alexey Tolstov, Ken'ichi Nomoto, Elena Sorokina +3
Recent supernova searches revealed a number of fast-evolving luminous transients. We perform radiation hydrodynamic simulations of light curves of several models of supernova from…
Extended Optical/NIR Observations of Type Iax Supernova 2014dt: Possible Signatures of a Bound Remnant
Miho Kawabata, Koji S. Kawabata, Keiich Maeda +19
We present optical and near-infrared observations of the nearby Type Iax supernova (SN) 2014dt from 14 to 410 days after the maximum light. The velocities of the iron absorption li…
Optical follow-up observation of Fast Radio Burst 151230
Nozomu Tominaga, Yuu Niino, Tomonori Totani +9
The origin of fast radio bursts (FRBs), bright millisecond radio transients, is still somewhat of a mystery. Several theoretical models expect that the FRB accompanies an optical a…
The Fast, Luminous Ultraviolet Transient AT2018cow: Extreme Supernova, or Disruption of a Star by an Intermediate-Mass Black Hole?
Daniel A. Perley, Paolo A. Mazzali, Lin Yan +60
Wide-field optical surveys have begun to uncover large samples of fast (t_rise < 5d), luminous (M_peak < -18), blue transients. While commonly attributed to the breakout of a super…
Progenitor Mass Distribution of Core-Collapse Supernova Remnants in Our Galaxy and Magellanic Clouds based on Elemental Abundances
Satoru Katsuda, Tomoya Takiwaki, Nozomu Tominaga +2
We investigate a progenitor mass distribution of core-collapse supernova remnants (CCSNRs) in our Galaxy and the Large and Small Magellanic Clouds, for the first time. We count the…
Influence of Earth-Directed Coronal Mass Ejections on the Sun's Shadow Observed by the Tibet-III Air Shower Array
M. Amenomori, X. J. Bi, D. Chen +78
We examine the possible influence of Earth-directed coronal mass ejections (ECMEs) on the Sun's shadow in the 3~TeV cosmic-ray intensity observed by the Tibet-III air shower (AS) a…
