Mel. Hopwood et al., A possible detection of diffuse extended X-ray emission in the environmentof the globular cluster NGC 6779, M NOT R AST, 316(1), 2000, pp. L5-L8
We report the possible detection of diffuse X-ray emission in the environme
nt of NGC 6779, and find the emission to be well aligned with the proper mo
tion of the cluster. The position of the emission suggests we are observing
heated ISM in the wake of the cluster that could be the result of an inter
action between the intracluster medium and the halo gas surrounding it.
