Scientific paper

ESO137-001 is a small starburst galaxy in the nearby massive cluster A3627. A 70 kpc long X-ray tail behind ESO 137-001 has been revealed by both Chandra and XMM data, which makes it the only known late-type galaxy with an X-ray tail in a Coma-like cluster. Our SOAR observations also reveal a 40 kpc Halpha tail in the position of the X-ray tail, as well as 30 intracluster HII regions in or around the tail. We propose HST observations of this unique galaxy to resolve the distorted galactic structures in transformation, and to search for yound star clusters in or around the tail, and to understand star formation in the galaxy and in the intracluster space. The results will be of general interest to galaxy transformation in clusters {e.g., ''Butcher-Oemler'' galaxies at z>0.3}, starburst induced by ICM pressure, and intracluster star formation.;
