The impact of two massive early accretion events in a Milky Way-like galaxy: repercussions for the buildup of the stellar disc and halo

Matthew D. A. Orkney, Chervin F. P. Laporte, Robert J. J. Grand +5

We identify and characterise a Milky Way-like realisation from the Auriga simulations with two consecutive massive mergers $\sim 2$ Gyr apart at high redshift, comparable to the re…

EDGE: the puzzling ellipticity of Eridanus II's star cluster and its implications for dark matter at the heart of an ultra-faint dwarf

Matthew D. A. Orkney, Justin I. Read, Oscar Agertz +6

The Eridanus II (EriII) 'ultra-faint' dwarf has a large ( $15 pc$ ) and low mass ( $4.3 \times 1 0^{3} M_{⊙}$ ) star cluster (SC) offset from its centre by $23\pm3\,\text{…
