SUMMARY OF SEQUENCE NUMBER 800106
Title: X-RAY SEARCH FOR DARK GRAVITATIONAL LENSES
Observer: Hattori
Subject Category: Clusters of Galaxies
Seq: 800106 ObsId: 00930
Long-term Plan bin: 16-Apr-2000
ABSTRACT
Within these two decades a plenty of astronomical phenomena which are caused by gravitational lensing have been reported. In some of those, lensing objects have not been identified in spite of a relatively deep search for lensing objects by optical observations and the yet unknown lensing objects are called "dark lenses". We have been doing a X-ray search for dark lens objects and successfully identified a distant cluster of galaxies as a dark lens object. In this proposal, high resolution X-ray search for two dark lens objects are proposed. For one of the targets, Q2345+007, lensing interpretation for this system is tested by resolving X-ray emission from two images.
