Serendipitous Discovery of an Optically-Dark Ultra-Luminous Infrared Galaxy at = 3.4
N. H. Hayatsu, Zhi-Yu Zhang, R. J. Ivison +10
Dusty, submillimeter-selected galaxies without optical counterparts contribute a non-negligible fraction of the star formation in the early universe. However, such a population is…
Constraining the Mass of a Hypothetical Secondary Black Hole in M87 with the NANOGrav 15-Year Data Set
Motoki Kino, Masahiro Nagashima, Hyunwook Ro +3
Galaxy mergers, each hosting a supermassive black hole (SMBH), are thought to form SMBH binaries. Motivated by recent observations from the East Asian VLBI Network (EAVN) showing p…
The origin of the metallicity difference between star-forming and passive galaxies: Insights from ν2GC semi-analytic model
Qiansheng Liu, Takashi Okamoto, Taira Oogi +1
We investigate the origin of the observed metallicity difference between star-forming and passive galaxies using the semi-analytic galaxy formation model nu2GC. Our fiducial model…
The evolution of supermassive blackhole mass--bulge mass relation by a semi-analytic model, GC
Tatsuki Shimizu, Taira Oogi, Takashi Okamoto +2
We have investigated the redshift evolution of the relationship between supermassive black hole (SMBH) mass and host bulge mass using a semi-analytical galaxy formation model …
The History of The Milky Way: The Evolution of Star Formation, Cosmic Rays, Metallicity, and Stellar Dynamics over Cosmic Time
Jiro Shimoda, Shu-ichiro Inutsuka, Masahiro Nagashima
We study the long-term evolution of the Milky Way (MW) over cosmic time by modeling the star formation, cosmic rays, metallicity, stellar dynamics, outflows and inflows of the gala…
Uchuu-GC galaxies and AGN: Cosmic variance forecasts of high-redshift AGN for JWST, Euclid, and LSST
Taira Oogi, Tomoaki Ishiyama, Francisco Prada +10
Measurements of the luminosity function of active galactic nuclei (AGN) at high redshift () are expected to suffer from field-to-field variance, including cosmic and Po…
