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…
Age and metallicity of low-mass galaxies: from their centres to their stellar halos
Elisa A. Tau, Antonela Monachesi, Facundo A. Gómez +5
We aim to analyse the metallicity and the ages of the stellar halos of low-mass galaxies to better understand their formation history. We use 17 simulated low-mass galaxies from 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…
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…
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…
