Small scale cosmological perturbations: An Analytic approach
- W. Hu, N. Sugiyama
- Physics
- 23 October 1995
Through analytic techniques verified by numerical calculations, we establish general relations between the matter and cosmic microwave background (CMB) power spectra and their dependence on… Expand
Simulations of Early Structure Formation: Primordial Gas Clouds
- N. Yoshida, T. Abel, L. Hernquist, N. Sugiyama
- Physics
- 31 January 2003
We use cosmological simulations to study the origin of primordial star-forming clouds in a ΛCDM universe, by following the formation of dark matter halos and the cooling of gas within them. To model… Expand
The fmos-cosmos survey of star-forming galaxies at z ~ 1.6. I. Hα-based star formation rates and dust extinction
- D. Kashino, J. Silverman, +26 authors Y. Taniguchi
- Physics
- 18 September 2013
We present the first results from a near-IR spectroscopic survey of the COSMOS field, using the Fiber Multi-Object Spectrograph on the Subaru telescope, designed to characterize the star-forming… Expand
Cosmic background anistropies in CDM cosmology
- N. Sugiyama
- Physics
- 7 December 1994
Cosmic microwave background (CMB) anisotropies and density fluctuations are calculated for flat cold dark matter (CDM) models with a wide range of parameters, i.e., $\Omega_0, h$ and $\Omega_B$ for… Expand
MeV-scale reheating temperature and thermalization of the neutrino background
- M. Kawasaki, K. Kohri, N. Sugiyama
- Physics
- 6 February 2000
The late-time entropy production by the massive particle decay induces the various cosmological effects in the early epoch and modify the standard scenario. We investigate the thermalization process… Expand
The FMOS-COSMOS Survey of Star-forming Galaxies at z ~ 1.6. II. The Mass-Metallicity Relation and the Dependence on Star Formation Rate and Dust Extinction
- H. Zahid, D. Kashino, +28 authors The Cosmos Team
- Physics
- 18 October 2013
We investigate the relationships between stellar mass, gas-phase oxygen abundance (metallicity), star formation rate (SFR), and dust content of star-forming galaxies at z ~ 1.6 using Subaru/FMOS… Expand
The Japanese space gravitational wave antenna?DECIGO
- S. Kawamura, M. Ando, +142 authors K. Sun
- Physics
- 21 April 2006
DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is the future Japanese space gravitational wave antenna. It aims at detecting various kinds of gravitational waves between 1 mHz and… Expand
Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137deg$^2$ of the sky. Thanks to the high effective galaxy number… Expand
The Hyper Suprime-Cam SSP Survey: Overview and Survey Design
- H. Aihara, N. Arimoto, +139 authors S. Yuma
- Physics
- 19 April 2017
Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of the 8.2m Subaru telescope on the summit of Maunakea. A team of scientists from Japan, Taiwan and Princeton University is… Expand
Subaru high-z exploration of low-luminosity quasars (SHELLQs). I. Discovery of 15 quasars and bright galaxies at 5.7 < z < 6.9
- Y. Matsuoka, M. Onoue, +36 authors Y. Utsumi
- Physics
- 7 March 2016
We report the discovery of 15 quasars and bright galaxies at 5.7 6 galaxies, compared with that of quasars, at magnitudes fainter than M1450 ~ -22 mag or zAB ~24 mag. Follow-up studies of the… Expand
