Uncovering the Orbit of the Hercules Dwarf Galaxy
Alexandra L. Gregory, Michelle L. M. Collins, Denis Erkal +6
We present new chemo--kinematics of the Hercules dwarf galaxy based on Keck II-- DEIMOS spectroscopy. Our 21 confirmed members have a systemic velocity of $v_{\mathrm{Herc}}=46.4\p…
Intermediate-Mass Black Holes
Jenny E. Greene, Jay Strader, Luis C. Ho
We describe ongoing searches for intermediate-mass black holes with M_BH ~ 100-10^5 M_sun. We review a range of search mechanisms, both dynamical and those that rely on accretion s…
Surprisingly Strong K-band Emission Found in Low Luminosity Active Galactic Nuclei
Antoine Dumont, Anil Seth, Jay Strader +3
We examine the near-infrared (NIR) emission from low-luminosity AGNs (LLAGNs). Our galaxy sample includes 15 objects with detected 2-10 keV X-ray emission, dynamical black hole mas…
The SLUGGS Survey: Measuring globular cluster ages using both photometry and spectroscopy
Christopher Usher, Jean P. Brodie, Duncan A. Forbes +4
Globular cluster ages provide both an important test of models of globular cluster formation and a powerful method to constrain the assembly history of galaxies. Unfortunately, mea…
On the black hole content and initial mass function of 47 Tuc
Vincent Hénault-Brunet, Mark Gieles, Jay Strader +3
The globular cluster (GC) 47 Tuc has recently been proposed to host an intermediate-mass black hole (IMBH) or a population of stellar-mass black holes (BHs). To shed light on its d…
Signatures of Tidal Disruption in Ultra-Faint Dwarf Galaxies: A Combined HST, Gaia, and MMT/Hectochelle Study of Leo V
Burçin Mutlu-Pakdil, David J. Sand, Matthew G. Walker +10
The ultra-faint dwarf galaxy Leo V has shown both photometric overdensities and kinematic members at large radii, along with a tentative kinematic gradient, suggesting that it may…
