Made-to-Measure Modelling of Globular Clusters
Jeremy J. Webb, Jason A. S. Hunt, Jo Bovy
We present the first application of the made-to-measure method for modelling dynamical systems to globular clusters. Through the made-to-measure algorithm, the masses of individual…
Multiple phase spirals suggest multiple origins in Gaia DR3
Jason A. S. Hunt, Adrian M. Price-Whelan, Kathryn V. Johnston +1
{\it Gaia} Data Release 2 (DR2) revealed that the Milky Way contains significant indications of departures from equilibrium in the form of asymmetric features in the phase space de…
Dynamically constraining the length of the Milky Way bar
Madeline Lucey, Sarah Pearson, Jason A. S. Hunt +5
We present a novel method for constraining the length of the Galactic bar using 6D phase space information to directly integrate orbits. We define a pseudo-length for the Galactic…
Mapping Dark Matter with Extragalactic Stellar Streams: the Case of Centaurus A
Sarah Pearson, Adrian M. Price-Whelan, David W. Hogg +4
In the coming decade, thousands of stellar streams will be observed in the halos of external galaxies. What fundamental discoveries will we make about dark matter from these stream…
A direct measurement of the distance to the Galactic center using the kinematics of bar stars
Henry W. Leung, Jo Bovy, J. Ted Mackereth +3
The distance to the Galactic center is a fundamental parameter for understanding the Milky Way, because all observations of our Galaxy are made from our heliocentric referenc…
The emptiness inside: Finding gaps, valleys, and lacunae with geometric data analysis
Gabriella Contardo, David W. Hogg, Jason A. S. Hunt +2
Discoveries of gaps in data have been important in astrophysics. For example, there are kinematic gaps opened by resonances in dynamical systems, or exoplanets of a certain radius…
Weighing the Galactic disk using phase-space spirals IV. Tests on a three-dimensional galaxy simulation
Axel Widmark, Jason A. S. Hunt, Chervin F. P. Laporte +1
In this fourth article on weighing the Galactic disk using the shape of the phase-space spiral, we have tested our method on a billion particle three-dimensional N-body simulation,…
