STRRINGS: STReams in Residual Images of Nearby GalaxieS
E. Sola, D. Chemaly, V. Belokurov +11
Tidal features from galaxy mergers, particularly stellar streams, offer valuable insights into galaxy assembly and dark matter halo properties. This paper aims to identify a large…
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…
On the connection between nitrogen-enhanced field stars and the Galactic globular clusters
Sarah G. Kane, Vasily Belokurov, Stephanie Monty +6
As sites of some of the most efficient star formation in the Universe, globular clusters (GCs) have long been hypothesized to be the building blocks of young galaxies. Within the M…
Observational Constraints of Radial Migration in the Galactic Disc Driven by the Slowing Bar
HanYuan Zhang, Vasily Belokurov, N. Wyn Evans +7
Radial migration is an important dynamical effect that has reshaped the Galactic disc, but its origin has yet to be elucidated. In this work, we present evidence that resonant drag…
The ratio of [Eu/] differentiates accreted/in-situ Milky Way stars across metallicities, as indicated by both field stars and globular clusters
Stephanie Monty, Vasily Belokurov, Jason L. Sanders +7
We combine stellar orbits with the abundances of the heavy, -process element europium and the light, -element, silicon to separate in-situ and accreted populations in the Mi…
Is the RSGC4 (Alicante 8) cluster a real star cluster?: Peculiar radial velocities of red supergiant stars
Sang-Hyun Chun, GyuChul Myeong, Jae-Joon Lee +1
Young massive star clusters, like the six red supergiant clusters in the Scutum complex, provide valuable insights into star-formation and galaxy structures. We investigated the hi…
