Testing Cosmological Models by Gravitational Lensing: I. Method and First Applications
Joachim Wambsganss, Renyue Cen, Jeremiah P. Ostriker
Gravitational lensing directly measures mass density fluctuations along the lines of sight to very distant objects. No assumptions need to be made concerning bias, the ratio of flu…
Effects of Weak Gravitational Lensing from Large-Scale Structure on the Determination of
Joachim Wambsganss, Renyue Cen, Guohong Xu +1
Weak gravitational lensing by large-scale structure affects the determination of the cosmological deceleration parameter . We find that the lensing induced dispersions on trul…
ROSAT/HRI study of the optically rich, lensing cluster CL0500-24
Sabine Schindler, Joachim Wambsganss
An analysis of a ROSAT/HRI observation of the optically rich, gravitationally lensing galaxy cluster CL0500-24 (or Abell S0506) is presented. We show that the X-ray luminosity of t…
