----- Attempting Submission 1 (Thu Sep 01 01:44:01 GMT 2011) ----- X-raying the spectacular star-forming trail behind IC 3418 The ICM has long been proposed to play a vital role in galaxy evolution in clusters, through stripping of the 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. It is now known that star formation indeed happens commonly in the stripped ISM, but a lot of detail is still unknown. We propose a 35 ks ACIS-S observation of a dwarf galaxy with a remarkable star-forming trail in the Virgo cluster. Its proximity provides an unprecedented opportunity to study the evolution of the stripped gas, intracluster X-ray binaries and star formation. Joint HST and EVLA data observations are also requested.
We will use WFC3 and ACS to study the dwarf galaxy IC 3418 and its star-forming trail in the Virgo cluster. The WFC3 F275W data in one orbit will be used to study the young star clusters in the galaxy and the gaseous tail. We will also get the F475W and F814W data. The data will be compared with the similar data we have for ESO 137-001 and ESO 137-002 in A3627.
