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…
A closer look at the spur, blob, wiggle, and gaps in GD-1
T. J. L. de Boer, D. Erkal, M. Gieles
The GD-1 stream is one of the longest and coldest stellar streams discovered to date, and one of the best objects for constraining the dark matter properties of the Milky Way. Usin…
Birds of a Feather? Magellan/IMACS Spectroscopy of the Ultra-Faint Satellites Grus II, Tucana IV, and Tucana V
J. D. Simon, T. S. Li, D. Erkal +54
We present Magellan/IMACS spectroscopy of three recently discovered ultra-faint Milky Way satellites, Grus II, Tucana IV, and Tucana V. We measure systemic velocities of V_hel = -1…
Evidence of a population of dark subhalos from Gaia and Pan-STARRS observations of the GD-1 stream
Nilanjan Banik, Jo Bovy, Gianfranco Bertone +2
New data from the satellite, when combined with accurate photometry from the Pan-STARRS survey, allow us to accurately estimate the properties of the GD-1 stream. H…
Proper Motions of Stellar Streams Discovered in the Dark Energy Survey
N. Shipp, T. S. Li, A. B. Pace +12
We cross-match high-precision astrometric data from Gaia DR2 with accurate multi-band photometry from the Dark Energy Survey (DES) DR1 to confidently measure proper motions for nin…
Limit on the LMC mass from a census of its satellites
Denis Erkal, Vasily A. Belokurov
We study the orbits of ultra-faint dwarf galaxies in the combined presence of the Milky Way and LMC and we find 6 dwarfs which were likely accreted with the LMC (Car 2, Car 3, Hor…
