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…
Mitigating the impact of fiber assignment on the measurement of galaxy-lensing cross correlation
Ryu Makiya, Tomomi Sunayama
We examine the impact of fiber assignment on the measurement of galaxy clustering and its cross correlation with weak lensing fields. Unlike the past spectroscopic galaxy surveys s…
Ray-tracing log-normal simulation for weak gravitational lensing: application to the cross-correlation with galaxies
Ryu Makiya, Issha Kayo, Eiichiro Komatsu
We present an algorithm to self-consistently generate mock weak gravitational lensing convergence fields and galaxy distributions in redshift space. We generate three-dimensional c…
The thermal and gravitational energy densities in the large-scale structure of the Universe
Yi-Kuan Chiang, Ryu Makiya, Eiichiro Komatsu +1
As cosmic structures form, matter density fluctuations collapse gravitationally and baryonic matter is shock-heated and thermalized. We therefore expect a connection between the me…
The Cosmic Thermal History Probed by Sunyaev-Zeldovich Effect Tomography
Yi-Kuan Chiang, Ryu Makiya, Brice Ménard +1
The cosmic thermal history, quantified by the evolution of the mean thermal energy density in the universe, is driven by the growth of structures as baryons get shock heated in col…

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…
Mitigating the impact of fiber assignment on clustering measurements from deep galaxy redshift surveys
Tomomi Sunayama, Masahiro Takada, Martin Reinecke +6
We examine the impact of fiber assignment on clustering measurements from fiber-fed spectroscopic galaxy surveys. We identify new effects which were absent in previous, relatively…
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…
New constraints on the mass bias of galaxy clusters from the power spectra of the thermal Sunyaev-Zeldovich effect and cosmic shear
Ryu Makiya, Chiaki Hikage, Eiichiro Komatsu
Thermal Sunyaev-Zeldovich (tSZ) power spectrum is a powerful probe of the present-day amplitude of matter density fluctuations, and has been measured up to from…

We present a first joint analysis of the power spectra of the thermal Sunyaev-Zeldovich (tSZ) effect measured by the Planck and the number density fluctuations of galaxies in the 2…

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…
