A tidally induced global corrugation pattern in an external disc galaxy similar to the Milky Way

Facundo A. Gómez, Sergio Torres-Flores, Catalina Mora-Urrejola +11

We study the two dimensional (2D) line-of-sight velocity () field of the low-inclination, late-type galaxy VV304a. The resulting 2D kinematic map reveals a global, coh…

The impact of magnetic fields on cosmological galaxy mergers. I: Reshaping gas and stellar discs

Joseph Whittingham, Martin Sparre, Christoph Pfrommer +1

Mergers play an important role in galaxy evolution. In particular, major mergers are able to have a transformative effect on galaxy morphology. In this paper, we investigate the ro…

The mass of the Milky Way out to 100 kpc using halo stars

Alis J. Deason, Denis Erkal, Vasily Belokurov +9

We use a distribution function analysis to estimate the mass of the Milky Way out to 100 kpc using a large sample of halo stars. These stars are compiled from the literature, and t…

Magnetogenesis around the first galaxies: the impact of different field seeding processes on galaxy formation

Enrico Garaldi, Rüdiger Pakmor, Volker Springel

We study the evolution of magnetic fields generated by charge segregation ahead of ionization fronts during the Epoch of Reionization, and their effects on galaxy formation. We com…

LYRA I: Simulating the multi-phase ISM of a dwarf galaxy with variable energy supernovae from individual stars

Thales A. Gutcke, Rüdiger Pakmor, Thorsten Naab +1

We introduce the LYRA project, a new high resolution galaxy formation model built within the framework of the cosmological hydro-dynamical moving mesh code AREPO. The model resolve…

Observing the stellar halo of Andromeda in cosmological simulations: the Auriga2PAndAS pipeline

Guillaume F. Thomas, Nicolas F. Martin, Azadeh Fattahi +10

We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of 6 galaxies from the Auriga simu…
