Magellan/M2FS Spectroscopy of Tucana 2 and Grus 1
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +8
We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of stellar targets along the line of sight to the newly-discovered `ultrafai…
A Hubble Space Telescope Study of the Enigmatic Milky Way Halo Globular Cluster Crater
Daniel R. Weisz, Sergey E. Koposov, Andrew E. Dolphin +6
We analyze the resolved stellar populations of the faint stellar system, Crater, based on deep optical imaging taken with the Hubble Space Telescope. The HST/ACS-based color-magnit…
Evidence That Hydra I is a Tidally Disrupting Milky Way Dwarf Galaxy
Jonathan R. Hargis, B. Kimmig, B. Willman +6
The Eastern Banded Structure (EBS) and Hydra~I halo overdensity are very nearby (d 10 kpc) objects discovered in SDSS data. Previous studies of the region have shown that EB…
A low pre-infall mass for the Carina dwarf galaxy from disequilibrium modelling
Uğur Ural, Mark I. Wilkinson, Justin I. Read +1
Dark matter only simulations of galaxy formation predict many more subhalos around a Milky Way like galaxy than the number of observed satellites. Proposed solutions require the sa…
Magellan/M2FS Spectroscopy of the Reticulum 2 Dwarf Spheroidal Galaxy
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +4
We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of 182 stellar targets along the line of sight to the newly-discovered `ultrafaint…
The SLUGGS Survey: Multi-population dynamical modelling of the elliptical galaxy NGC 1407 from stars and globular clusters
Vincenzo Pota, Aaron J. Romanowsky, Jean P. Brodie +7
We perform in-depth dynamical modelling of the luminous and dark matter (DM) content of the elliptical galaxy NGC 1407. Our strategy consists of solving the spherical Jeans equatio…
