We have obtained high-resolution K ′ -band images of the powerful z = 1.206 radio galaxy 3C 324 with the Subaru telescope under seeing conditions of 0 ′′ .3–0 ′′ .4. We clearly resolved the galaxy and directly compared it to the optical images obtained with the Hubble Space Telescope. The host galaxy of 3C 324 is revealed to be a moderately luminous elliptical galaxy with a smooth light profile. The effective radius of the galaxy, as determined by profile fitting, is 1.3± 0 ′′ .1 (1.2 kpc…

Subaru Observations of the Host Galaxies and the Environments of the Radio Galaxy 3C324 at Z = 1.1

3C 324 is a proto-typical powerful radio galaxy with strong UV-optical alignment effect. The object is known to sit in the dense environment of the galaxies at the same distance. In this

Witnessing the Hierarchical Assembly of the Brightest Cluster Galaxy in a Cluster at z = 1.26

We have obtained a new high-resolution K′-band image of the central region of the rich X-ray cluster RX J0848.9+4452 at z = 1.26. We found that the brightest cluster galaxy (BCG) in the cluster is

An ISOCAM survey through gravitationally lensing galaxy clusters. III. New results from mid-infrared observations of the cluster Abell 2219

The massive cluster of galaxies Abell 2219 (z = 0.228) with two spectacular gravitational lensing arcs was observed at 14.3 µm (hereafter 15 µm) with the Infrared Space Observatory and results were
