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…

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…
