Dusty ERO Search behind Two Massive Clusters

Ohyama, Youichi; Kawabata, Koji S.; Yoshida, Michitoshi +15 more

We performed deep K'-band imaging observations of 2 massive clusters, MS 0451.6 - 0305 at z = 0.55 and MS 0440.5 + 0204 at z = 0.19, for searching counterparts of the faint sub-mm sources behind these clusters, which would provide one of the deepest extremely red object (ERO) samples. Comparing our near-infrared images with optical images taken by…

The Virgo High-Resolution CO Survey: III. NGC 4254

Nakanishi, Hiroyuki; Koda, Jin; Sofue, Yoshiaki +1 more

We present high-angular-resolution (1''.5 - 5'') interferometer observations of the ¹²CO (J = 1--0) line emission in the central region of the SA(s)c galaxy NGC 4254 (M 99). The observations were obtained using the Nobeyama Millimeter-wave Array (NMA) during the course of a long-term CO-line survey of Virgo spirals. We present the spect…
