SUMMARY OF PROPOSAL 41036 DR. KAZUO MAKISHIMA UNIVERSITY OF TOKYO TOKYO JAPAN 113 BUNKYO-KU 7-3-1 HONGO E-mail: MAXIMA@MIRANDA.PHYS.S.U-TOKYO.AC.JP Tel: 03-3812-2111 EX.4171 Fax: 03-3812-6938 Medium: 2.5GB8MM Subject: X-RAY BINARIES Title: DEEP POINTING ONTO THE GLOBULAR CLUSTER M4 (NGC 6121) Abstract: We search for diffuse bow-shock emission from the nearest globular cluster M4, to obtain insight into a large-scale flow in the hot Galactic halo. If there is a strong outward flow in the halo away from the Galactic plane, we would expect the bow shock to be facing the galactic plane. We also attempt to detect dim X-ray sources in M4, including the millisecond pular PSR B1620-26.
