Detection of a distinct metal-poor stellar halo in the early-type galaxy NGC 3115
Mark B. Peacock, Jay Strader, Aaron J. Romanowsky +1
We present the resolved stellar populations in the inner and outer halo of the nearby lenticular galaxy NGC~3115. Using deep HST observations, we analyze stars two magnitudes faint…
Measuring Consistent Masses for 25 Milky Way Globular Clusters
Brian Kimmig, Anil Seth, Inese I. Ivans +4
We present central velocity dispersions, masses, mass to light ratios (s), and rotation strengths for 25 Galactic globular clusters. We derive radial velocities of 1951 stars…
The SLUGGS survey: Globular cluster stellar population trends from weak absorption lines in stacked spectra
Christopher Usher, Duncan A. Forbes, Jean P. Brodie +7
As part of the SLUGGS survey, we stack 1137 Keck DEIMOS spectra of globular clusters from 10 galaxies to study their stellar populations in detail. The stacked spectra have median…
A Supermassive Black Hole in an Ultracompact Dwarf Galaxy
Anil Seth, Remco van den Bosch, Steffen Mieske +11
Ultracompact dwarf galaxies (UCDs) are among the densest stellar systems in the universe. These systems have masses up to 200 million solar masses, but half light radii of just 3-5…
Nitrogen abundances and multiple stellar populations in the globular clusters of the Fornax dSph
S. S. Larsen, J. P. Brodie, F. Grundahl +1
We use measurements of nitrogen abundances in red giants to search for multiple stellar populations in the four most metal-poor globular clusters (GCs) in the Fornax dwarf spheroid…
The AIMSS Project II: Dynamical-to-Stellar Mass Ratios Across the Star Cluster - Galaxy Divide
Duncan A. Forbes, Mark A. Norris, Jay Strader +5
The previously clear division between small galaxies and massive star clusters is now occupied by objects called ultra compact dwarfs (UCDs) and compact ellipticals (cEs). Here we…
