Spectropolarimetry of the superwind filaments of the starburst galaxy M82: kinematics of dust outflow
Michitoshi Yoshida, Koji S. Kawabata, Youichi Ohyama
Spectropolarimetry results for the starburst galaxy M82 are presented. The optical emission lines of the filaments in the energetic outflow ("superwind") from the nuclear starburst…
Optical and Near-Infrared Photometry of Nova V2362 Cyg : Rebrightening Event and Dust Formation
Akira Arai, Makoto Uemura, Koji S. Kawabata +20
We present optical and near-infrared (NIR) photometry of a classical nova, V2362 Cyg (= Nova Cygni 2006). V2362 Cyg experienced a peculiar rebrightening with a long duration from 1…
Statistics of 207 Lya Emitters at a Redshift Near 7: Constraints on Reionization and Galaxy Formation Models
Masami Ouchi, Kazuhiro Shimasaku, Hisanori Furusawa +12
We present Lya luminosity function (LF), clustering measurements, and Lya line profiles based on the largest sample, to date, of 207 Lya emitters (LAEs) at z=6.6 on the 1-deg^2 sky…
Substellar Companions to Evolved Intermediate-Mass Stars: HD 145457 and HD 180314
Bun'ei Sato, Masashi Omiya, Yujuan Liu +15
We report the detections of two substellar companions orbiting around evolved intermediate-mass stars from precise Doppler measurements at Subaru Telescope and Okayama Astrophysica…
A dozen new galaxies caught in the act: Gas stripping and extended emission line regions in the Coma cluster
Masafumi Yagi, Michitoshi Yoshida, Yutaka Komiyama +8
We present images of extended H-alpha clouds associated with 14 member galaxies in the Coma cluster obtained from deep narrow band imaging observations with Suprime-Cam at the Suba…
