Observing Cosmic-Ray Extensive Air Showers with a Silicon Imaging Detector
Satoshi Kawanomoto, Michitaro Koike, Fraser Bradfield +7
Extensive air showers induced from high-energy cosmic rays provide a window into understanding the most energetic phenomena in the universe. We present a new method for observing t…
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…
Photospheric carbon, nitrogen, and oxygen abundances of A-type main-sequence stars
Yoichi Takeda, Satoshi Kawanomoto, Naoko Ohishi +4
Based on the spectrum fitting method applied to CI 5380, NI 7486, and OI 6156-8 lines, we determined the abundances of C, N, and O for 100 mostly A-type main-sequence stars (late B…
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…
Fourier analysis of He 4471/Mg 4481 line profiles for separating rotational velocity and axial inclination in rapidly-rotating B-type stars
Y. Takeda, S. Kawanomoto, N. Ohishi
While the effect of rotation on spectral lines is complicated in rapidly-rotating stars because of the appreciable gravity-darkening effect differing from line to line, it is possi…
