Dynamical Mass Estimates For Two Luminous Star Clusters In Galactic Merger Remnants

ASTRONOMY & ASTROPHYSICS, no. 3 (2006): 881-891

Abstract

We present high-dispersion spectra of two extremely massive star clusters in galactic merger remnants, obtained using the UVES spectrograph mounted on the ESO Very Large Telescope. One cluster, W30, is located in the similar to 500 Myr old merger remnant NGC 7252 and has a velocity dispersion and effective radius of sigma = 27.5 +/- 2.5 k...More
