Velocity Dispersions of Massive Quiescent Galaxies from Weak Lensing and Spectroscopy
Yousuke Utsumi, Margaret J. Geller, Harus J. Zahid +6
We use MMT spectroscopy and deep Subaru Hyper Suprime-Cam (HSC) imaging to compare the spectroscopic central stellar velocity dispersion of quiescent galaxies with the effective di…
CHORUS. III. Photometric and Spectroscopic Properties of Ly Blobs at
Haibin Zhang, Masami Ouchi, Ryohei Itoh +20
We report the Subaru Hyper Suprime-Cam (HSC) discovery of two Ly blobs (LABs), dubbed z70-1 and z49-1 at and respectively, that are Ly emitters with a bri…
CHORUS II. Subaru/HSC Determination of the Ly Luminosity Function at : Constraints on Cosmic Reionization Model Parameter
Ryohei Itoh, Masami Ouchi, Haibin Zhang +16
We present the Ly luminosity function (LF) derived from 34 Ly emitters (LAEs) at on the sky of deg, the largest sample compared to those in the literature o…
A weak lensing view of the downsizing of star-forming galaxies
Yousuke Utsumi, Margaret J. Geller, Ian P. Dell'Antonio +14
We describe a weak lensing view of the downsizing of star forming galaxies based on cross correlating a weak lensing () map with a predicted map constructed from a redshift surv…
