Blind source separation of the stellar halo
Elliot Y. Davies, Vasily Belokurov, Andrey Kravtsov +4
The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and \textit{in-situ} evolution, that form an interweaving tapestry in kinemati…
Deciphering the Milky Way disc formation time encrypted in the bar chrono-kinematics
Hanyuan Zhang, Vasily Belokurov, N. Wyn Evans +3
We present a novel method to constrain the formation time of the Milky Way disc using the chrono-kinematic signatures of the inner Galaxy. We construct an O-rich Mira variable samp…
Kinematics and dynamics of the Galactic bar revealed by Gaia long-period variables
Hanyuan Zhang, Vasily Belokurov, N. Wyn Evans +2
We use low-amplitude, long period variable (LA-LPV) candidates in \textit{Gaia} DR3 to trace the kinematics and dynamics of the Milky Way bar. LA-LPVs, like other LPVs, are intrins…
Trojan globular clusters: radial migration via trapping in bar resonances
Adam M. Dillamore, Stephanie Monty, Vasily Belokurov +1
We search for globular clusters (GCs) trapped in resonances with the bar of the Milky Way. By integrating their orbits in a potential with a decelerating bar, we select 10 whose or…
Radial halo substructure in harmony with the Galactic bar
Adam M. Dillamore, Vasily Belokurov, N. Wyn Evans
Overdensities in the radial phase space of the Milky Way's halo have previously been associated with the phase-mixed debris of a highly radial merger event, such as Gaia…
