EDGE: The origin of scatter in ultra-faint dwarf stellar masses and surface brightnesses
Martin P. Rey, Andrew Pontzen, Oscar Agertz +4
We demonstrate how the least luminous galaxies in the Universe, ultra-faint dwarf galaxies, are sensitive to their dynamical mass at the time of cosmic reionization. We select a lo…
Constraining churning and blurring in the Milky Way using large spectroscopic surveys -- an exploratory study
Sofia Feltzing, J. Bradley Bowers, Oscar Agertz
We have investigated the possibilities to quantify how much stars move in the Milky Way stellar disk due to diffuse processes (i.e. so called blurring) and due to influences from s…
EDGE: the mass-metallicity relation as a critical test of galaxy formation physics
Oscar Agertz, Andrew Pontzen, Justin I. Read +7
We introduce the "Engineering Dwarfs at Galaxy formation's Edge" (EDGE) project to study the cosmological formation and evolution of the smallest galaxies in the Universe. In this…
Supernovae feedback propagation: the role of turbulence
Loke Ohlin, Florent Renaud, Oscar Agertz
Modelling the propagation of supernova (SN) bubbles, in terms of energy, momentum and spatial extent, is critical for simulations of galaxy evolution which do not capture these sca…
A diversity of starburst-triggering mechanisms in interacting galaxies and their signatures in CO emission
Florent Renaud, Frederic Bournaud, Oscar Agertz +5
The physical origin of enhanced star formation activity in interacting galaxies remains an open question. Knowing whether starbursts are triggered by an increase of the quantity of…
On the Observed Diversity of Star Formation Efficiencies in Giant Molecular Clouds
Kearn Grisdale, Oscar Agertz, Florent Renaud +3
Observations find a median star formation efficiency per free-fall time in Milky Way Giant Molecular Clouds (GMCs) on the order of with dispersions of $\sim0.5…
