Weak lensing mass reconstruction of MS1008.1-1224
M. Lombardi, P. Rosati, M. Nonino +3
We present an in-depth weak lensing analysis of the cluster MS1008 based on deep multicolor imaging obtained during the Science Verification of FORS1 at the VLT. The image quality…
BeppoSAX observations of two high redshift clusters of galaxies: RXJ0152.7-1357 and MS2053.7-0449
R. Della Ceca, R. Scaramella, I. M. Gioia +3
We present X-ray observations of two high redshift clusters of galaxies carried out with the BeppoSAX satellite. One cluster, RXJ0152.7-1357 at z = 0.83, was selected from the ROSA…
Recent Developments in Weak Lensing
Nick Kaiser, Gordon Squires, Greg Fahlman +2
Measurement of the gravitational distortion of images of distant galaxies is rapidly becoming established as a powerful probe of the dark mass distribution in clusters of galaxies.…
Mapping the Dark Matter in Clusters
Nick Kaiser, Gordon Squires, Greg Fahlman +1
Massive clusters of galaxies gravitationally shear the images of faint background galaxies. At large impact parameters the shear is weak, but can still be measured, to a reasonable…
