Scl-dE1 GC1: An Extended Globular Cluster in a Low-Luminosity Dwarf Elliptical Galaxy
G. S. Da Costa, E. K. Grebel, H. Jerjen +2
We report the discovery from Hubble Space Telescope ACS images of an extended globular cluster, denoted by Scl-dE1 GC1, in the Sculptor Group dwarf Elliptical galaxy Scl-dE1 (Sc22)…
Accretion and nuclear activity of quiescent supermassive black holes. II: optical study and interpretation
Roberto Soria, Alister W. Graham, Giuseppina Fabbiano +5
Our X-ray study of the nuclear activity in a new sample of six quiescent early-type galaxies, and in a larger sample from the literature, confirmed (Soria et al., Paper I) that the…
Accretion and nuclear activity of quiescent supermassive black holes. I: X-ray study
Roberto Soria, Giuseppina Fabbiano, Alister W. Graham +5
We have studied the nuclear activity in a sample of six quiescent early-type galaxies, with new Chandra data and archival HST optical images. Their nuclear sources have X-ray lumin…
