Examining Neutrino-Matter Interactions in the Cassiopeia A Supernova
Toshiki Sato, Takashi Yoshida, Hideyuki Umeda +4
Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confi…
Metal-enriched Pair-instability supernovae: Effects of rotation
Hideyuki Umeda, Chris Nagele
In this paper we revisit metal-enriched rotating pair instability supernovae (PISNe) models for metallicities consistent with the Small Magellanic Cloud (SMC), the Large Magellanic…
Formation of first star clusters under the supersonic gas flow -- I. Morphology of the massive metal-free gas cloud
Shingo Hirano, Youcheng Shen, Sho Nishijima +2
We performed simulations of the first star formation with initial supersonic gas flows relative to the dark matter at the cosmic recombination era. Increasing the initial stre…
Multiple channels for nitrogen pollution by metal enriched supermassive stars and implications for GN-z11
Chris Nagele, Hideyuki Umeda
GN-z11 is an unusually luminous high redshift galaxy which was recently observed to have strong nitrogen lines while at the same time lacking traditional signatures of AGN activity…
Evolution and explosions of metal enriched supermassive stars: proton rich general relativistic instability supernovae
Chris Nagele, Hideyuki Umeda, Koh Takahashi
The assembly of supermassive black holes poses a challenge primarily because of observed quasars at high redshift, but additionally because of the current lack of observations of i…
On the population III binary black hole mergers with intermediate mass black holes: dependence on common envelope parameter
Kotaro Hijikawa, Tomoya Kinugawa, Ataru Tanikawa +2
The current gravitational wave (GW) detectors have successfully observed many binary compact objects, and the third generation ground-based GW detectors such as Einstein telescope…
