Probing the gravitational potential of a nearby lensing cluster Abell 2104
H. Liang, L. Lemonon, I. Valtchanov +2
The cluster Abell 2104 is one of the lowest redshift clusters (z=0.153) known to have a gravitational lensing arc. We present detailed analysis of the cluster properties such as th…
Medium-distant clusters of galaxies seen by ISO
L. Lemonon, M. Pierre, C. J. Cesarsky +2
We present a comprehensive study of ISO cluster galaxies in connection with other wavelengths. First results show that infrared galaxies detected by ISOCAM concentrate on the edge…
Deep ISOCAM view of the core of the lensing cluster A2390
L. Lemonon, M. Pierre, C. J. Cesarsky +4
We have imaged the inner square arcminute of the well known lensing and cooling flow cluster A2390 (z = 0.23) down to a sensitivity of 65 and 130 microJy at 6.75 and 15 micronmetre…
X-ray/Optical analysis of the cluster of galaxies Abell 1300: Indications of a post-merger at z = 0.31
L. Lemonon, M. Pierre, R. Hunstead +3
We present ROSAT PSPC and HRI observations of the distant cluster A1300 (z = 0.3071) in conjunction with optical data, to investigate the physics of the intra-cluster medium and th…
