Giant H nebula surrounding the starburst merger NGC 6240

Michitoshi Yoshida, Masafumi Yagi, Youichi Ohyama +4

We revealed the detailed structure of a vastly extended H-emitting nebula ("H nebula") surrounding the starburst/merging galaxy NGC 6240 by deep narrow-band imaging observati…

Hyper-luminous Dust Obscured Galaxies discovered by the Hyper Suprime-Cam on Subaru and WISE

Yoshiki Toba, Tohru Nagao, Michael A. Strauss +31

We present the photometric properties of a sample of infrared (IR) bright dust obscured galaxies (DOGs). Combining wide and deep optical images obtained with the Hyper Suprime-Cam…
