Dusty ERO Search behind Two Massive Clusters

Tadafumi Takata, Nobunari Kashikawa, Kouichiro Nakanishi +15

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 sour…

ERO R1 in CL0939+4713 field - Evidence for an S0-like galaxy at z \sim 1.5

Masanori Iye, Kazuhiro Shimasaku, Satoshi Miyazaki +11

We present further observations of the extremely red object ERO J094258+4659.2, identified by \citet{iye00} as ERO R1 in their deep images of the cluster A851. We estimate its reds…

Superwind-Driven Intense H_2 Emission in NGC 6240

Youichi Ohyama, Michitoshi Yoshida, Tadafumi Takata +18

We have performed a long-slit K band spectroscopic observation of the luminous infrared galaxy NGC 6240. The peak position of the H_2 v=1-0 S(1) emission in the slit is located ~0.…
