OBSERVATION OF FOSSIL GALAXY GROUP RXJ1340.6+4018
ABSTRACT
We propose to study the formation process of a unique system RXJ1340.6+4018 called 'fossil garaxy group'. This diffuse (~500 kpc), hot (kT~0.9keV) emission at z=0.171 is extremely gas and rich system and cannot be classified neither as a group of galaxies nor as an elliptical galaxy with a large halo. ASCA measurement of its metal abundance will give us an important clue to study the formation process of this system.
