SUMMARY OF PROPOSAL 41102 DR TAKAYA OHASHI TOKYO METROPOLITAN UNIVERSITY TOKYO JAPAN 192-03 HACHIOJI 1-1, MINAMI-OHSAWA E-mail: OHASHI@PHYS.METRO-U.AC.JP Tel: +81-426-77-2492 Fax: +81-426-77-2483 Medium: 4GBDAT Subject: NORMAL GALAXIES Title: THE DARK MATTER IN THE BRIGHT ELLIPTICAL GALAXY: NGC4636 Abstract: To derive a reliable estimate for the darkmatter amound in elliptical galaxies, we propose to observe NGC4636 for 100 ksec. This observation determines whether the darkmatter only belongs to individual galaxies or there is a component in the cluster scale. The proposed target is one of the brightest elliptical galaxies, and its isolated location gives ideal opportunity for the present study.
