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 (…
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…
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…
Updated observational constraints on quintessence dark energy models
Jean-Baptiste Durrive, Junpei Ooba, Kiyotomo Ichiki +1
The recent GW170817 measurement favors the simplest dark energy models, such as a single scalar field. Quintessence models can be classified in two classes, freezing and thawing, d…
