On the shoulders of giants: properties of the stellar halo and the milky way mass distribution
Halo stars orbit within the potential of the Milky Way, and hence their kinematics can be used
to understand the underlying mass distribution. However, the inferred mass distribution …

The shape of the inner milky way halo from observations of the Pal 5 and GD–1 Stellar Streams
J Bovy, A Bahmanyar, TK Fritz… - The Astrophysical …, 2016 - iopscience.iop.org
We constrain the shape of the Milky Way's halo by dynamical modeling of the observed
phase-space tracks of the Pal 5 and GD–1 tidal streams. We find that the only information …

And yet it moves: the dangers of artificially fixing the Milky Way center of mass in the presence of a massive Large Magellanic Cloud
FA Gómez, G Besla, DD Carpintero… - The Astrophysical …, 2015 - iopscience.iop.org
Motivated by recent studies suggesting that the Large Magellanic Cloud (LMC) could be
significantly more massive than previously thought, we explore whether the approximation of …

Evidence of a population of dark subhaloes from Gaia and Pan-STARRS observations of the GD-1 stream
New data from the Gaia satellite, when combined with accurate photometry from the Pan-
STARRS survey, allow us to accurately estimate the properties of the GD-1 stream. Here, we …
