THE NARROW X-RAY TAIL AND DOUBLE Hα TAILS OF ESO 137-002 IN A3627

We present the analysis of a deep Chandra observation of a ~2 L sub(*) late-type galaxy, ESO 137-002, in the closest rich cluster A3627. The Chandra data reveal a long ([gap]40 kpc) and narrow tail with a nearly constant width (~3 kpc) to the southeast of the galaxy, and a leading edge ~L5 kpc from...

Description
Summary:We present the analysis of a deep Chandra observation of a ~2 L sub(*) late-type galaxy, ESO 137-002, in the closest rich cluster A3627. The Chandra data reveal a long ([gap]40 kpc) and narrow tail with a nearly constant width (~3 kpc) to the southeast of the galaxy, and a leading edge ~L5 kpc from the galaxy center on the upstream side of the tail. The derived gas abundance is low (~0.2 solar with the single-kT model), an indication of the multiphase nature of the gas in the tail. The mass of the X-ray tail is only a small fraction (
