OBSERVATION OF ELLIPTICAL GALAXIES WHICH ARE SUGGESTED TO BE MERGERS


ABSTRACT

We propose to observe elliptical galaxies, NGC3640 and NGC3610, which are suggested to be formed through mergers of disk galaxies several Gyrs ago. Then we can compare the difference of X-ray luminosity, gas temperature and abundance of hot gas between these galaxies and normal ellipitical galaxies in rich clusters of galaxies.
