How much can we learn from resolved stellar kinematics of galactic haloes using action-based dynamical models?
Paula Gherghinescu, Eugene Vasiliev, Payel Das +1
Dynamical models are used to study dark matter (DM) in galaxies, how galaxies assemble through mergers, and to test galaxy formation models. Despite its widespread use, there has b…
Stellar velocity distributions in binary-rich ultrafaint dwarf galaxies
Amery Gration, David D. Hendriks, Payel Das +2
Ultrafaint dwarf (UFD) galaxies are dominated by dark matter, the distribution of which may be inferred from the kinematics of that galaxy's stellar population. Star-by-star observ…
EDGE: The emergence of dwarf galaxy scaling relations from cosmological radiation-hydrodynamics simulations
Martin P. Rey, Ethan Taylor, Emily I. Gray +14
We present a new suite of EDGE (`Engineering Dwarfs at Galaxy formation's Edge') cosmological zoom simulations. The suite includes 15 radiation-hydrodynamical dwarf galaxies coveri…
