Pulsational pair-instability and the mass gap of Population III Black Holes: Effects of overshooting
Hideyuki Umeda, Takashi Yoshida, Chris Nagele +1
Since the discovery of GW190521, several proposals have been put forward to explain the formation of a black hole in the mass gap caused by (pulsational) pair-instability, $M = 65-…
Three-flavor collective neutrino conversions with multi-azimuthal-angle instability in an electron-capture supernova model
Masamichi Zaizen, Shunsaku Horiuchi, Tomoya Takiwaki +4
We investigate the multi-azimuthal angle (MAA) effect on collective neutrino oscillation by considering the three-dimensional neutrino momentum distribution in a realistic electron…
Population III Binary Black Holes: Effects of Convective Overshooting on Formation of GW190521
Ataru Tanikawa, Tomoya Kinugawa, Takashi Yoshida +2
GW190521 is a merger of two black holes (BHs), wherein at least one BH lies within the pair-instability (PI) mass gap, and it is difficult to form because of the effects of PI supe…
Merger rate density of Population III binary black holes below, above, and in the pair-instability mass gap
Ataru Tanikawa, Hajime Susa, Takashi Yoshida +2
We present the merger rate density of Population (Pop.) III binary black holes (BHs) by means of a widely-used binary population synthesis code BSE with extensions to very massive…
The Final Fate of Supermassive Pop III Stars: Explosion or Collapse?
Chris Nagele, Hideyuki Umeda, Koh Takahashi +2
We investigate the possibility of a supernova in supermassive () population III stars induced by a general relativistic instability occurring in the helium…
Theoretical prediction of presupernova neutrinos and their detection
Chinami Kato, Koji Ishidoshiro, Takashi Yoshida
Almost 30 years have passed since the successful detection of supernova neutrinos from SN 1987A. In the last decades, remarkable progress has been made in neutrino detection techni…
