A hot X-ray tail from a transforming galaxy in A3627
Abstract
The ICM has long been proposed to play a vital role in galaxy evolution in clusters, through stripping of the galactic cold gas. Studies of gaseous tails behind cluster late-type galaxies have shed light on the energy transfer in the multi-phase gas, demonstrated by the recent discoveries of X-ray tails, intracluster star-formation and ULXs in the stripped gas. We propose a 95 ks ACIS-S observation of a surprisingly hot X-ray tail of ESO137-002 in A3627, as well as joint HST observations in three orbits. These observations aim to confirm the first hot X-ray tails in clusters, study the substructure in the X-ray tail (double tails? a possible extension to 100 kpc?), search for and study more intracluster ULXs and star formation. We have supporting data of optical spectroscopy, HI and CO.
