An extended Pal 5 stream in Gaia DR2
Nathaniel Starkman, Jo Bovy, Jeremy Webb
We present the results of a detailed search for members of the Pal 5 tidal tail system in Gaia Data Release 2 (DR2). Tidal tails provide a sensitive method for measuring the curren…
The Effect of Dwarf Galaxies on the Tidal Tails of Globular Clusters
Nada El-Falou, Jeremy Webb
The tidal tails of globular clusters have been shown to be sensitive to the external tidal field. We investigate how Galactic globular clusters with observed tails are affected by…
Towards characterizing dark matter subhalo perturbations in stellar streams with graph neural networks
Peter Xiangyuan Ma, Keir K. Rogers, Ting S. Li +4
The phase space of stellar streams is proposed to detect dark substructure in the Milky Way through the perturbations created by passing subhalos - and thus is a powerful test of t…
The ejection and detectability of high- and hyper-velocity stars by compact object binaries in globular clusters
Fraser A. Evans, Steffani M. Grondin, Claire S. Ye +3
The dense cores of Milky Way globular clusters (GCs) play host to a variety of dynamical encounters between stellar objects, which can accelerate stars to velocities high enough to…
Characteristic radii of the Milky Way Globular Clusters
Andrés E. Piatti, Jeremy Webb, Raymond Carlberg
We report on the extent of the effects of the Milky Way's gravitational field in shaping the structural parameters and internal dynamics of its globular cluster population. We make…
The Effect of Stellar Helium Abundance on Dynamics of Multiple Populations in Globular Clusters
Amy Fare, Jeremy Webb, Alison Sills
We incorporate a semi-analytic formula for the main sequence lifetime of helium-rich stars in N-body simulations of multiple population globular clusters to investigate how the enr…
