Breaking Beta: A comparison of mass modelling methods for spherical systems
J. I. Read, G. A. Mamon, E. Vasiliev +6
We apply four different mass modelling methods to a suite of publicly available mock data for spherical stellar systems. We focus on the recovery of the density and velocity anisot…
Can tides explain the low dark matter density in Fornax?
Anna Genina, Justin I. Read, Azadeh Fattahi +1
The low dark matter density in the Fornax dwarf galaxy is often interpreted as being due to the presence of a constant density `core', but it could also be explained by the effects…
Formation of the largest galactic cores through binary scouring and gravitational wave recoil
Imran Nasim, Alessia Gualandris, Justin I. Read +3
Massive elliptical galaxies are typically observed to have central cores in their projected radial light profiles. Such cores have long been thought to form through `binary scourin…
EDGE: A new approach to suppressing numerical diffusion in adaptive mesh simulations of galaxy formation
Andrew Pontzen, Martin P. Rey, Corentin Cadiou +4
We introduce a new method to mitigate numerical diffusion in adaptive mesh refinement (AMR) simulations of cosmological galaxy formation, and study its impact on a simulated dwarf…
VINTERGATAN I: The origins of chemically, kinematically and structurally distinct discs in a simulated Milky Way-mass galaxy
Oscar Agertz, Florent Renaud, Sofia Feltzing +6
Spectroscopic surveys of the Milky Way's stars have revealed spatial, chemical and kinematical structures that encode its history. In this work, we study their origins using a cosm…
VINTERGATAN III: how to reset the metallicity of the Milky Way
Florent Renaud, Oscar Agertz, Eric P. Andersson +5
Using the cosmological zoom simulation VINTERGATAN, we present a new scenario for the onset of star formation at the metal-poor end of the low-[/Fe] sequence in a Milky Way-like…
VINTERGATAN II: the history of the Milky Way told by its mergers
Florent Renaud, Oscar Agertz, Justin I. Read +5
Using the VINTERGATAN cosmological zoom simulation, we explore the contributions of the in situ and accreted material, and the effect of galaxy interactions and mergers in the asse…
Defeating stochasticity: coalescence timescales of massive black holes in galaxy mergers
Imran Nasim, Alessia Gualandris, Justin Read +3
The coalescence of massive black hole binaries (BHBs) in galactic mergers is the primary source of gravitational waves (GWs) at low frequencies. Current estimates of GW detection r…
EDGE: From quiescent to gas-rich to star-forming low-mass dwarf galaxies
Martin P. Rey, Andrew Pontzen, Oscar Agertz +3
We study how star formation is regulated in low-mass field dwarf galaxies (), using cosmological high-resolution ($3 \, \text{pc}…
Revealing the tidal scars of the Small Magellanic Cloud
Michele De Leo, Ricardo Carrera, Noelia E. D. Noel +3
Due to their close proximity, the Large and Small Magellanic Clouds (SMC/LMC) provide natural laboratories for understanding how galaxies form and evolve. With the goal of determin…
