We present high signal-to-noise Keck spectra for 10 globular clusters associated with the giant Fornax elliptical galaxy NGC 1399 and compare measured line indices with current stellar population models. Our data convincingly demonstrate, for the first time, that at least some of the clusters in a giant elliptical galaxy have supersolar abundance

A 2-D global hybrid simulation is carried out to study the structure of the dayside magnetopause in the noon-midnight meridian plane associated with magnetic reconnection. In the simulation the bow shock, magnetosheath, and magnetopause are formed self-consistently by supersonic solar wind passing the geomagnetic field. The reconnection events at

We will present analysis of the diffuse emission from the nucleus of M31 using a 40 ks Chandra ACIS-S observation. The observation was taken by Chandra on 5 October, 2001. This is a continuation of our work performed on a 5 ks observation with the Chandra ACIS-I detector, presented as a poster paper at the 2001 ASP conference. With this observation

The formation of quasar broad-line region (BLR) clouds via thermal instability in the presence of Alfvén heating has been discussed by Gonçalves, Jatenco-Pereira & Opher. In particular, these studies showed the relevance of Alfvén heating in establishing the stability of BLR clouds in the intercloud medium. The present paper shows the results of
