Small scale cosmological perturbations: An Analytic approach
- Wayne 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…
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…
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…
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, 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…
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…
The Japanese space gravitational wave antenna?DECIGO
- S. Kawamura, M. Ando, 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…
Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
- C. Hikage, M. Oguri, Yoshihiko Yamada
- PhysicsPublications of the Astronomical Society of Japan
- 24 September 2018
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137 deg2 of the sky. Thanks to the high effective galaxy number…
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, 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…
