Thermal Sunyaev-Zel'dovich Effect in the IGM due to Primordial Magnetic Fields
Teppei Minoda, Kenji Hasegawa, Hiroyuki Tashiro +2
In the present universe, magnetic fields exist with various strengths and on various scales. One possible origin of these cosmic magnetic fields is the primordial magnetic fields (…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). V. Quasar Luminosity Function and Contribution to Cosmic Reionization at z = 6
Yoshiki Matsuoka, Michael A. Strauss, Nobunari Kashikawa +44
We present new measurements of the quasar luminosity function (LF) at , over an unprecedentedly wide range of the rest-frame ultraviolet luminosity from …
Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
Chiaki Hikage, Masamune Oguri, Takashi Hamana +34
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137deg of the sky. Thanks to the high effect…
Stellar mass dependence of the 21-cm signal around the first star and its impact on the global signal
Toshiyuki Tanaka, Kenji Hasegawa, Hidenobu Yajima +2
The 21-cm signal in the vicinity of the first stars is expected to reflect properties of the first stars. In this study we pay special attention to tracing the time evolution of th…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). IV. Discovery of 41 Quasars and Luminous Galaxies at 5.7 < z < 6.9
Y. Matsuoka, K. Iwasawa, M. Onoue +44
We report discovery of 41 new high-z quasars and luminous galaxies, which were spectroscopically identified at 5.7 < z < 6.9. This is the fourth in a series of papers from the Suba…
Planck 2015 constraints on spatially-flat dynamical dark energy models
Junpei Ooba, Bharat Ratra, Naoshi Sugiyama
We determine constraints on spatially-flat tilted dynamical dark energy XCDM and CDM inflation models by analyzing Planck 2015 cosmic microwave background (CMB) anisotropy data…
