Ja n 20 00 Evidence for Stellar Streaming in the Cores of Elliptical Galaxies : A Kinematic Signature of Mergers ?

Abstract

We present evidence for non-Gaussian velocity fields within the cores of luminous elliptical galaxies. This evidence is based upon high signal-to-noise, medium-resolution spectroscopy of the cores of early-type members of the Virgo and Coma clusters obtained with the WIYN 3.5-m telescope. The Virgo data were acquired using an integral-field unit (DensePak… (More)
