EDGE-INFERNO: The chemical signatures of assembly history in reionization fossils
Eric P. Andersson, Martin P. Rey, Alexander P. Ji +9
In galaxies, stellar populations represent a superposition of both in situ and accreted components, tracing internal chemical evolution as well as the histories of merged satellite…
The emergence of globular clusters and globular-cluster-like dwarfs
Ethan D. Taylor, Justin I. Read, Matthew D. A. Orkney +7
Globular clusters (GCs) are among the oldest and densest stellar systems in the Universe, yet how they form remains a mystery. Here we present a suite of cosmological simulations i…
FEAST: JWST uncovers the emerging timescales of young star clusters in M83
Alice Knutas, Angela Adamo, Alex Pedrini +23
We present JWST NIRCam observations of the emerging young star clusters (eYSCs) detected in the nearby spiral galaxy M83. The NIRcam mosaic encompasses the nuclear starburst, the b…
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…
EDGE-INFERNO: Simulating every observable star in faint dwarf galaxies and their consequences for resolved-star photometric surveys
Eric P. Andersson, Martin P. Rey, Andrew Pontzen +4
Interpretation of data from faint dwarf galaxies is made challenging by observations limited to only the brightest stars. We present a major improvement to tackle this challenge by…
EDGE: A new model for Nuclear Star Cluster formation in dwarf galaxies
Emily I. Gray, Justin I. Read, Ethan Taylor +8
Nuclear Star Clusters (NSCs) are amongst the densest stellar systems in the Universe and are found at the centres of many bright spiral and elliptical galaxies, and up to 4…
Composition of Giants 1 North of the Galactic Center: Detailed Abundance Trends for 21 Elements Observed with IGRINS
Govind Nandakumar, Nils Ryde, Gregory Mace +10
We report the first high resolution, detailed abundances of 21 elements for giants in the Galactic bulge/bar within of the Galactic plane, where high extinction has rende…
Emergence and cosmic evolution of the Kennicutt-Schmidt relation driven by interstellar turbulence
Katarina Kraljic, Florent Renaud, Yohan Dubois +12
The scaling relations between the gas content and star formation rate of galaxies provide useful insights into processes governing their formation and evolution. We investigate the…
Pre-supernova feedback sets the star cluster mass function to a power law and reduces the cluster formation efficiency
Eric P. Andersson, Mordecai-Mark Mac Low, Oscar Agertz +2
The star cluster initial mass function is observed to have an inverse power law exponent around 2, yet there is no consensus on what determines this distribution, and why some vari…
EDGE: The direct link between mass growth history and the extended stellar haloes of the faintest dwarf galaxies
Alex Goater, Justin I. Read, Noelia E. D. Noël +9
Ultra-faint dwarf galaxies (UFDs) are commonly found in close proximity to the Milky Way and other massive spiral galaxies. As such, their projected stellar ellipticity and extende…
PRISM: A Non-Equilibrium, Multiphase Interstellar Medium Model for Radiation Hydrodynamics Simulations of Galaxies
Harley Katz, Shenghua Liu, Taysun Kimm +7
We introduce the PRISM interstellar medium (ISM) model for thermochemistry and its implementation in the RAMSES-RTZ code. The model includes a non-equilibrium primordial, metal, an…
INFERNO: Galactic winds in dwarf galaxies with star-by-star simulations including runaway stars
Eric P. Andersson, Oscar Agertz, Florent Renaud +1
The formation and evolution of galaxies have proved sensitive to the inclusion of stellar feedback, which is therefore crucial to any successful galaxy model. We present INFERNO, a…
EDGE: The sensitivity of ultra-faint dwarfs to a metallicity-dependent initial mass function
Mateo Prgomet, Martin P. Rey, Eric P. Andersson +5
Motivated by the observed bottom-light initial mass function (IMF) in faint dwarfs, we study how a metallicity-dependent IMF affects the feedback budget and observables of an ultra…
Runaway stars masquerading as star formation in galactic outskirts
Eric P. Andersson, Florent Renaud, Oscar Agertz
In the outskirts of nearby spiral galaxies, star formation is observed in extremely low gas surface densities. Star formation in these regions, where the interstellar medium is dom…
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…
How runaway stars boost galactic outflows
Eric P. Andersson, Oscar Agertz, Florent Renaud
Roughly ten per cent of OB stars are kicked out of their natal clusters before ending their life as supernovae. These so-called runaway stars can travel hundreds of parsecs into th…
Tidal stripping as a mechanism for placing globular clusters on wide orbits: the case of MGC1 in M31
Eric P. Andersson, Melvyn B. Davies
The globular clusters of large spiral galaxies can be divided into two populations: one which formed in-situ and one which comprises clusters tidally stripped away from other galax…
