Impact of Gaia-Sausage-Enceladus merger revealed by a single cosmic clock: thick-to-thin disc transition, gas disc shrinking and bar formation
Natsuki Funakoshi, Daisuke Kawata, Jason L. Sanders +5
Whether the formation of the Galactic bar was connected to the Gaia-Sausage-Enceladus (GSE) merger, the last significant merger experienced by the Milky Way, remains an open questi…
Hidden Disruption in Milky Way-like Satellite Galaxy Populations
Gray Thoron, Nora Shipp, Alexander H. Riley +9
Determining whether a satellite galaxy is tidally disrupting from photometric observations alone remains a fundamental challenge in near-field cosmology. Cosmological simulations o…
Uncovering the origin of complex velocity distributions in edge-on disc galaxies
Sophie Townson, Marie Martig, Robert J. J. Grand +3
Stellar line-of-sight velocity distributions are a powerful tool for studying galaxy kinematics and formation history, with multiple-peaked LOSVDs often indicating the presence of…
Same galaxy, different CGM: how the metal loading of galactic winds regulates the baryon cycle in Milky Way-mass galaxies
Prachi Khatri, Freeke van de Voort, Rebekka Bieri +5
The circumgalactic medium (CGM) is both the reservoir of gas that fuels star formation and galaxy growth, and the repository for the mass, energy, and metals expelled through stell…
Introducing AuriGLOBES: The effects of compressive tides, compact object-induced mass loss, and size evolution on modelling globular clusters
Pablo Contreras Guerra, Robert J. J. Grand, Marta Reina-Campos +1
Globular clusters (GCs) are long time survivors of galaxy assembly and evolution yet their emergence from an initial cluster population is still poorly constrained. We present the…
AGN-driven outflows in dwarf galaxies from cosmological simulations: Internal properties and observational signatures
Elena Arjona-Gálvez, Arianna Di Cintio, Robert J. J. Grand +4
While AGN feedback is a key driver of massive galaxy evolution, its physical properties and observational signatures in the dwarf regime remain poorly understood. We investigate th…
Coupling between stellar and HI lopsidedness in Milky Way-type galaxies from the Auriga Superstars cosmological simulations
Arianna Dolfi, Facundo A. Gómez, Rebekka Bieri +5
Lopsidedness is common in disk galaxies, yet its origin and evolution remain unclear. Previous studies typically examined stellar and gas asymmetries separately, but a combined ana…
A simulation-based inference of the Milky Way merger history
Andrea Sante, Andreea S. Font, Daisuke Kawata +2
Accreted stars in the Milky Way (MW) preserve information about the progenitor galaxies where they formed in their chemical and kinematic properties. In this study, we use the chem…
Winding, Unwinding, Rewinding the Gaia Phase Spiral
Neige Frankel, Marcin Semczuk, Teresa Antoja +10
The Gaia Space Satellite has transformed the field of Galactic Dynamics by collecting 6D phase space information for hundreds of millions of stars. In 2018, it enabled the discover…
The diverse nature of spiral arms in the Auriga Superstars cosmological hydrodynamic simulations
Robert J J Grand, Francesca Fragkoudi, Rüdiger Pakmor +4
The dynamical nature and formation mechanism(s) of galactic spiral arms remain long-standing problems in astrophysics. Most theoretical work is based on analytic calculations or id…
What drives bar rotation? The effect of internal properties and galaxy interactions on bar pattern speeds
Alex Merrow, Francesca Fragkoudi, Rob J. J. Grand +1
One of the main properties of galactic bars is their rotation (or pattern) speed, which is driven by both internal galactic properties, as well as external interactions. To assess…
Stirring Things Up: Bar-induced substructures in the stellar halo of a cosmological Milky Way analogue
Thomas Tomlinson, Francesca Fragkoudi, Andreia Carrillo +8
The stellar halo of the Milky Way contains the remnants of past accretion events, which could be detectable as substructures in the classical integrals of motion space, such as ene…
