Mapping dusty star formation in and around a cluster at z=0.81 by wide-field imaging with AKARI
Yusei Koyama, Tadayuki Kodama, Kazuhiro Shimasaku +8
We present environmental dependence of dusty star forming activity in and around the cluster RXJ1716.4+6708 at z=0.81 based on wide-field and multi-wavelength observations with Sup…
Strange filamentary structures ("fireballs") around a merger galaxy in the Coma cluster of galaxies
M. Yoshida, M. Yagi, Y. Komiyama +6
We found an unusual complex of narrow blue filaments, bright blue knots, and H-alpha emitting filaments and clouds, which morphologically resembled a complex of ``fireballs,'' exte…
Dependence of the Build-up of the Colour-Magnitude Relation on Cluster Richness at z ~ 0.8
Yusei Koyama, Tadayuki Kodama, Masayuki Tanaka +2
We present environmental dependence of the build-up of the colour-magnitude relation (CMR) at z ~ 0.8. It is well established that massive early-type galaxies exhibit a tight CMR i…
