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…
On the origin of counterrotating stellar disks in TNG50. I
M. C. Bugueño, Facundo A. Gómez, Arianna Dolfi +1
Understanding galaxy evolution is key to explaining the structures we observe in the present-day Universe. Counterrotating stellar disks (CRDs), i.e. co-spatial stellar disks rotat…
A statistical study of lopsided galaxies using random forest
Valentina Fontirroig, Facundo A. Gomez, Marcelo Jaque Arancibia +2
Lopsided galaxies are late-type galaxies with a non-axisymmetric disk due to an uneven distribution of their stellar mass. Despite being a relatively common perturbation, several q…
Tracing the origins of galaxy lopsidedness across cosmic time
Arianna Dolfi, Facundo A. Gomez, Antonela Monachesi +3
Current studies of large-scale asymmetries (i.e. lopsidedness) in the stellar density distribution of disk galaxies have mainly focused on the local Universe. Recent observations h…
