Radial arc statistics: A new powerful probe of the central density profile of galaxy clusters
Kohji Molikawa, Makoto Hattori
We show that an expected number ratio of radial arcs (gravitationally lensed images whose major axes lie in the radial direction of a cluster-lens potential) to tangential arcs (gr…

Spectroscopic confirmation of a cluster of galaxies at z=1 in the field of the gravitational lens MG2016+112
G. Soucail, J. P. Kneib, A. O. Jaunsen +3
We present new optical data on the cluster AX J2019+1127 identified by the X-ray satellite ASCA at z\sim 1 (Hattori et al. 1997). The data suggest the presence of a high-redshift c…
