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 …
Possible evolution of the circum-galactic medium around QSOs with QSO age and cosmic time revealed by Ly halos
Rieko Momose, Tomotsugu Goto, Yousuke Utsumi +6
We first present new Subaru narrow-band observations of the Ly halo around the quasi-stellar object (QSO) CFHQ J232908030158 at , which appears the most luminous and…
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…
Weak-Lensing Mass Calibration of ACTPol Sunyaev-Zel'dovich Clusters with the Hyper Suprime-Cam Survey
Hironao Miyatake, Nicholas Battaglia, Matt Hilton +57
We present weak-lensing measurements using the first-year data from the Hyper Suprime-Cam Strategic Survey Program on the Subaru telescope for eight galaxy clusters selected throug…
Wavelength Dependent PSFs and their impact on Weak Lensing Measurements
S. G. Carlsten, Michael A. Strauss, Robert H. Lupton +2
We measure and model the wavelength dependence of the PSF in the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) survey. We find that PSF chromaticity is present in that red…
A Detection of the Environmental Dependence of the Sizes and Stellar Haloes of Massive Central Galaxies
Song Huang, Alexie Leauthaud, Jenny Greene +6
We use ~100 square deg of deep (>28.5 mag arcsec in i-band), high-quality (median 0.6 arcsec seeing) imaging data from the Hyper Suprime-Cam (HSC) survey to reveal the halo…
