Cosmic evolution of grain size distribution in galaxies using the GC semi-analytic model
Ryu Makiya, Hiroyuki Hirashita
We investigate the cosmological evolution of interstellar dust with a semi-analytical galaxy formation model (GC), focusing on the evolution of grain size distribution. The mo…
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…
Quantifying the effect of field variance on the H luminosity function with the New Numerical Galaxy Catalogue (GC)
Kazuyuki Ogura, Masahiro Nagashima, Rhythm Shimakawa +9
We construct a model of H emitters (HAEs) based on a semi-analytic galaxy formation model, the New Numerical Galaxy Catalog (GC). In this paper, we report our estimate for…
A young galaxy cluster in the old Universe
Tetsuya Hashimoto, Tomotsugu Goto, Rieko Momose +4
Galaxies evolve from a blue star-forming phase into a red quiescent one by quenching their star formation activity. In high density environments, this galaxy evolution proceeds ear…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) III. Star formation properties of the host galaxies at studied with ALMA
Takuma Izumi, Masafusa Onoue, Hikari Shirakata +26
We present our ALMA Cycle 4 measurements of the [CII] emission line and the underlying far-infrared (FIR) continuum emission from four optically low-luminosity ($M_{\rm 1450} > -25…
The New Numerical Galaxy Catalogue (ν^2 GC): Properties of Active Galactic Nuclei and Their Host Galaxies
Hikari Shirakata, Takashi Okamoto, Toshihiro Kawaguchi +7
We present the latest results of a semi-analytic model of galaxy formation, "New Numerical Galaxy Catalogue", which is combined with large cosmological N-body simulations. This mod…
Imprints of the super-Eddington accretion on the quasar clustering
Taira Oogi, Motohiro Enoki, Tomoaki Ishiyama +5
Super-Eddington mass accretion has been suggested as an efficient mechanism to grow supermassive black holes (SMBHs). We investigate the imprint left by the radiative efficiency of…
SXDF-ALMA 2-arcmin^2 Deep Survey: Stacking of Rest-Frame Near-Infrared Selected Objects
Wei-Hao Wang, Kotaro Kohno, Bunyo Hatsukade +24
We present stacking analyses on our ALMA deep 1.1 mm imaging in the SXDF using 1.6 μm and 3.6 μm selected galaxies in the CANDELS WFC3 catalog. We detect a stacked flux of ~0.03-0.…
SXDF-ALMA 2 Arcmin^2 Deep Survey: Resolving and Characterizing the Infrared Extragalactic Background Light Down to 0.5 mJy
Yuki Yamaguchi, Yoichi Tamura, Kotaro Kohno +22
We present a multi-wavelength analysis of five submillimeter sources (S_1.1mm = 0.54-2.02 mJy) that were detected during our 1.1-mm-deep continuum survey in the SXDF-UDS-CANDELS fi…
Theoretical reevaluations of the black hole mass - bulge mass relation - I. Effect of the seed black hole mass
Hikari Shirakata, Toshihiro Kawaguchi, Takashi Okamoto +7
We explore the effect of varying the mass of the seed black hole on the resulting black hole mass - bulge mass relation at z ~ 0, using a semi-analytic model of galaxy formation co…
Quasar clustering in a galaxy and quasar formation model based on ultra high-resolution N-body simulations
Taira Oogi, Motohiro Enoki, Tomoaki Ishiyama +3
We investigate clustering properties of quasars using a new version of our semi-analytic model of galaxy and quasar formation with state-of-the-art cosmological N-body simulations.…
ALMA Deep Field in SSA22: A concentration of dusty starbursts in a z=3.09 protocluster core

We report the results of mapping at 1.1~mm with the Atacama Large Millimeter/submillimeter Array (ALMA) toward the central region of the SS…
SXDF-ALMA 1.5 arcmin^2 deep survey. A compact dusty star-forming galaxy at z=2.5
Ken-ichi Tadaki, Kotaro Kohno, Tadayuki Kodama +23
We present first results from the SXDF-ALMA 1.5 arcmin^2 deep survey at 1.1 mm using Atacama Large Millimeter Array (ALMA). The map reaches a 1sigma depth of 55 uJy/beam and covers…
Optical-Infrared Properties of Faint 1.3 mm Sources Detected with ALMA
Bunyo Hatsukade, Kouji Ohta, Kiyoto Yabe +3
We report optical-infrared (IR) properties of faint 1.3 mm sources (S_1.3mm = 0.2-1.0 mJy) detected with the Atacama Large Millimeter/submillimeter Array (ALMA) in the Subaru/XMM-N…
The New Numerical Galaxy Catalog (GC): An Updated Semi-analytic Model of Galaxy and AGN with Large Cosmological N-body Simulation
Ryu Makiya, Motohiro Enoki, Tomoaki Ishiyama +6
We present a new cosmological galaxy formation model, GC, as an updated version of our previous model GC. We adopt the so-called "semi-analytic" approach, in which the form…
