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…
Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal): IV. On the inner Milky Way stellar age distribution
Tomás Ruiz-Lara, David Mirabal, Carme Gallart +15
The Milky Way's inner region is dominated by a stellar bar and a boxy-peanut shaped bulge. However, which stellar populations inhabit the inner Galaxy or how star formation proceed…
Unveiling the Impact of Cosmic Rays on the Disc Sizes and Outflows from Dwarf Scales to Galaxy Groups
Rebekka Bieri, Rüdiger Pakmor, Freeke van de Voort +4
Cosmic rays (CRs) are a non-thermal energy component in the interstellar and circumgalactic medium (CGM) that can act as an additional feedback channel beyond thermal and kinetic f…
Auriga Superstars: Improving the resolution and fidelity of stellar dynamics in cosmological galaxy simulations
Ruediger Pakmor, Francesca Fragkoudi, Robert J. J. Grand +7
Cosmological hydrodynamical simulations have become an indispensable tool to understand galaxies. However, computational constraints still severely limit their numerical resolution…
Quantifying the intrinsic variability due to randomness of the Auriga galaxy formation model
Ruediger Pakmor, Rebekka Bieri, Francesca Fragkoudi +6
Numerical simulations have become an indispensable tool in astrophysics. To interpret their results, it is critical to understand their intrinsic variability, that is, how much the…
Stellar-gas kinematic misalignments in EAGLE: enhanced SMBH growth in misaligned galaxies
Maximilian K. Baker, Timothy A. Davis, Freeke van de Voort +1
Stellar-gas kinematic misalignments are a transient phenomenon observed in of the local galaxy population. According to current models, misaligned gas is expected to los…
Understanding gas mixing in the circumgalactic medium
Hilay Shah, Freeke van de Voort, Amit Seta +1
We study gas mixing in a simulated Milky Way-mass galaxy's circumgalactic medium (CGM) using cosmological `zoom-in' simulations. We insert tracer dyes in the CGM with different gas…
The halo mass dependence of physical and observable properties in the circumgalactic medium
Andrew W. S. Cook, Freeke van de Voort, Rüdiger Pakmor +1
We study the dependence of the physical and observable properties of the CGM on its halo mass. We analyse 22 simulations from the Auriga suite of high resolution cosmological `zoom…
Environment matters: stronger magnetic fields in satellite galaxies
Maria Werhahn, Rüdiger Pakmor, Rebekka Bieri +3
Magnetic fields are ubiquitous in the universe and an important component of the interstellar medium. It is crucial to accurately model and understand their properties in different…
Formation and fate of low metallicity stars in IllustrisTNG50
Ruediger Pakmor, Christine M. Simpson, Freeke van de Voort +6
Low metallicity stars give rise to unique spectacular transients and are of immense interest for understanding stellar evolution. Their importance has only grown further with the r…
Gas accretion and galactic fountain flows in the Auriga cosmological simulations: angular momentum and metal re-distribution
Robert J. J. Grand, Freeke van de Voort, Jolanta Zjupa +7
Using a set of 15 high-resolution magnetohydrodynamic cosmological simulations of Milky Way formation, we investigate the origin of the baryonic material found in stars at redshift…
Neutron star mergers and rare core-collapse supernovae as sources of r-process enrichment in simulated galaxies
Freeke van de Voort, Rüdiger Pakmor, Robert J. J. Grand +3
We use cosmological, magnetohydrodynamical simulations of Milky Way-mass galaxies from the Auriga project to study their enrichment with rapid neutron capture (r-process) elements.…
The impact of feedback and the hot halo on the rates of gas accretion onto galaxies
Camila A. Correa, Joop Schaye, Freeke van de Voort +2
We investigate the physics that drives the gas accretion rates onto galaxies at the centers of dark matter haloes using the EAGLE suite of hydrodynamical cosmological simulations.…
An ALMA view of star formation efficiency suppression in early-type galaxies after gas-rich minor mergers
Freeke van de Voort, Timothy A. Davis, Satoki Matsushita +6
Gas-rich minor mergers contribute significantly to the gas reservoir of early-type galaxies (ETGs) at low redshift, yet the star formation efficiency (SFE; the star formation rate…
On the deuterium abundance and the importance of stellar mass loss in the interstellar and intergalactic medium
Freeke van de Voort, Eliot Quataert, Claude-André Faucher-Giguère +5
We quantify the gas-phase abundance of deuterium and fractional contribution of stellar mass loss to the gas in cosmological zoom-in simulations from the Feedback In Realistic Envi…
The impact of stellar feedback on hot gas in galaxy haloes: the Sunyaev-Zel'dovich effect and soft X-ray emission
Freeke van de Voort, Eliot Quataert, Philip F. Hopkins +5
The thermal Sunyaev-Zel'dovich (SZ) effect and soft X-ray emission are routinely observed around massive galaxies and in galaxy groups and clusters. We study these observational di…
