An extended halo around an ancient dwarf galaxy
Anirudh Chiti, Anna Frebel, Joshua D. Simon +7
The Milky Way is surrounded by dozens of ultra-faint (< solar luminosities) dwarf satellite galaxies. They are the surviving remnants of the earliest galaxies, as confirmed…
Detection of the LMC-induced sloshing of the Galactic halo
Denis Erkal, Alis J. Deason, Vasily Belokurov +8
A wealth of recent studies have shown that the LMC is likely massive, with a halo mass . One consequence of having such a nearby and massive neighbour is that the…
The mass of the Milky Way out to 100 kpc using halo stars
Alis J. Deason, Denis Erkal, Vasily Belokurov +9
We use a distribution function analysis to estimate the mass of the Milky Way out to 100 kpc using a large sample of halo stars. These stars are compiled from the literature, and t…
On the origin of a rotating metal-poor stellar population in the Milky Way Nuclear Cluster
Manuel Arca Sedda, Alessia Gualandris, Tuan Do +3
We explore the origin of a population of stars recently detected in the inner parsec of the Milky Way Nuclear Cluster (NC), which exhibit sub-solar metallicity and a higher rotatio…
Discovery of an Ultra-Faint Stellar System near the Magellanic Clouds with the DECam Local Volume Exploration (DELVE) Survey
W. Cerny, A. B. Pace, A. Drlica-Wagner +29
We report the discovery of a new ultra-faint stellar system found near the Magellanic Clouds in the DECam Local Volume Exploration (DELVE) Survey. This new system, DELVE J015568…
Tango for three: Sagittarius, LMC, and the Milky Way
Eugene Vasiliev, Vasily Belokurov, Denis Erkal
We assemble a catalogue of candidate Sagittarius stream members with 5d and 6d phase-space information, using astrometric data from Gaia DR2, distances estimated from RR Lyrae star…
