Hints of a disrupted binary dwarf galaxy in the Sagittarius stream
Elliot Y. Davies, Stephanie Monty, Vasily Belokurov +1
In this work, we look for evidence of a non-unity mass ratio binary dwarf galaxy merger in the Sagittarius stream. Simulations of such a merger show that, upon merging with a host,…
Taking the Milky Way for a spin: disc formation in the ARTEMIS simulations
Adam M. Dillamore, Vasily Belokurov, Andrey Kravtsov +1
We investigate the formation (spin-up) of galactic discs in the ARTEMIS simulations of Milky Way-mass galaxies. In almost all galaxies discs spin up at higher [Fe/H] than the Milky…
Stellar halo striations from assumptions of axisymmetry
Elliot Y. Davies, Adam M. Dillamore, Vasily Belokurov +1
Motivated by the LMC's impact on the integral of motion space of the stellar halo, we run an -body merger simulation to produce a population of halo-like stars. We subsequently…
Accelerated phase-mixing in the stellar halo due to a rotating bar
Elliot Y. Davies, Adam M. Dillamore, Eugene Vasiliev +1
In a galaxy merger, the stars tidally stripped from the satellite and accreted onto the host galaxy undergo phase mixing and form finely-grained structures in the phase space. Howe…
Stellar halo substructure generated by bar resonances
Adam M. Dillamore, Vasily Belokurov, N. Wyn Evans +1
Using data from the Gaia satellite's Radial Velocity Spectrometer Data Release 3 (RVS, DR3), we find a new and robust feature in the phase space distribution of halo stars. It is a…
