Eccentric evolution of SMBH binaries
Masaki Iwasawa, Sangyong An, Tatsushi Matsubayashi +2
In recent numerical simulations \citep{matsubayashi07,lockmann08}, it has been found that the eccentricity of supermassive black hole(SMBH) - intermediate black hole(IMBH) binaries…
Evolution of Galactic Nuclei. I. orbital evolution of IMBH
Tatsushi Matsubayashi, Junichiro Makino, Toshikazu Ebisuzaki
Resent observations and theoretical interpretations suggest that IMBHs (intermediate-mass black hole) are formed in the centers of young and compact star clusters born close to the…
Absolute Rate, Evolving Luminosity function, and Evolving Jet Opening Angle Distribution for Long Gamma-Ray Bursts
Tatsushi Matsubayashi, Ryo Yamazaki, Daisuke Yonetoku +2
Using the luminosity function and the apparent GRB rate inferred from the spectral peak energy-luminosity relation, we investigate the absolute GRB formation rate, taking into acco…
The Reionization History and Early Metal Enrichment inferred from the Gamma-Ray Burst Rate
T. Murakami, D. Yonetoku, M. Umemura +2
Based on the gamma-ray burst (GRB) event rate at redshifts of , which is assessed by the spectral peak energy-to-luminosity relation recently found by Yonetoku et…
