Spectra of High Redshift Galaxies using a Cluster as a Gravitational Telescope
D. Mehlert, S. Seitz, R. P. Saglia +7
Using the Focal Reducer Spectrograph (FORS) at the Very Large Telescope (VLT) during the FORS commissioning time in December 1998 we took long slit spectra of the gravitational arc…
Entropy-regularized Maximum-Likelihood cluster mass reconstruction
Stella Seitz, Peter Schneider, Matthias Bartelmann
We present a new method for reconstructing two-dimensional mass maps of galaxy clusters from the image distortion of background galaxies. In contrast to most previous approaches, w…
A new finite-field mass reconstruction algorithm
Stella Seitz, Peter Schneider
A new method for the reconstruction of the projected mass distribution of clusters of galaxies from the image distortion of background galaxies is discussed. This method is essenti…
The Mass Distribution of CL0939+4713 obtained from a `Weak' Lensing Analysis of a WFPC2 image
Carolin Seitz, Jean-Paul Kneib, Peter Schneider +1
The image distortions of high-redshift galaxies caused by gravitational light deflection of foreground clusters of galaxies can be used to reconstruct the two-dimensional surface m…
The Density of 1-Jansky Sources Around Zwicky Clusters
Stella Seitz, Peter Schneider
In a recent paper by Rodrigues-Williams \& Hogan (RH94), a correlation between high-redshift, optically-selected QSOs and Zwicky clusters was reported at a very high significance l…
