Probing Cluster Potentials through Gravitational Lensing of Background X-Ray Sources
Refregier, Alexandre · Loeb, Abraham
Original · EN
We examine the gravitational lensing effect of a foreground galaxy cluster on the number count statistics of background X-ray sources. The lensing produces a deficit in the number of resolved sources in a ring close to the critical radius of the cluster. This deficit could be detected at the 3σ level with the AXAF-ACIS camera.
