Baryonic effects on the detectability of annihilation radiation from dark matter subhaloes around the Milky Way
Robert J J Grand, Simon D M White
We use six, high-resolution CDM simulations of galaxy formation to study how emission from dark matter annihilation is affected by baryonic processes. These simulations produce…
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…
Revisiting the tension between fast bars and the CDM paradigm
Francesca Fragkoudi, Robert J. J. Grand, Ruediger Pakmor +5
The pattern speed with which galactic bars rotate is intimately linked to the amount of dark matter in the inner regions of their host galaxies. In particular, dark matter haloes a…
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…
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…
The Hestia project: simulations of the Local Group
Noam I. Libeskind, Edoardo Carlesi, Rob J. J. Grand +19
We present the Hestia simulation suite: High-resolutions Environmental Simulations of The Immediate Area, a set of cosmological simulations of the Local Group. Initial conditions c…
The effect of magnetic fields on properties of the circumgalactic medium
Freeke van de Voort, Rebekka Bieri, Rüdiger Pakmor +3
We study the effect of magnetic fields on a simulated galaxy and its surrounding gaseous halo, or circumgalactic medium (CGM), within cosmological 'zoom-in' simulations of a Milky…
Stellar populations across galaxy bars in the MUSE TIMER project
Justus Neumann, Francesca Fragkoudi, Isabel Pérez +15
Stellar populations in barred galaxies save an imprint of the influence of the bar on the host galaxy's evolution. We present a detailed analysis of star formation histories (SFHs)…
Disentangling the formation history of galaxies via population-orbit superposition: method validation
Ling Zhu, Glenn van de Ven, Ryan Leaman +9
We present population-orbit superposition models for external galaxies based on Schwarzschild's orbit-superposition method, by tagging the orbits with age and metallicity. The mode…
Unveiling the Distinct Formation Pathways of the Inner and Outer Discs of the Milky Way with Bayesian Machine Learning
Ioana Ciucă, Daisuke Kawata, Andrea Miglio +2
We develop a Bayesian Machine Learning framework called BINGO (Bayesian INference for Galactic archaeOlogy) centred around a Bayesian neural network. After being trained on the APO…
A tale of two populations: surviving and destroyed dwarf galaxies and the build up of the Milky Way's stellar halo
Azadeh Fattahi, Alis J. Deason, Carlos S. Frenk +6
We use magneto-hydrodynamical simulations of Milky Way-mass haloes from the Auriga project to examine the properties of surviving and destroyed dwarf galaxies that are accreted by…
The Edge of the Galaxy
Alis J. Deason, Azadeh Fattahi, Carlos S. Frenk +5
We use cosmological simulations of isolated Milky Way-mass galaxies, as well as Local Group analogues, to define the "edge" -- a caustic manifested in a drop in density or radial v…
The orbital phase space of contracted dark matter halos
Thomas M. Callingham, Marius Cautun, Alis J. Deason +4
We study the orbital phase-space of dark matter (DM) halos in the AURIGA suite of cosmological hydrodynamics simulations of Milky Way analogues. We characterise halos by their sphe…
Sausage & Mash: The dual origin of the Galactic thick disc and halo from the gas-rich Gaia-Enceladus-Sausage merger
Robert J. J. Grand, Daisuke Kawata, Vasily Belokurov +6
We analyse a set of cosmological magneto-hydrodynamic simulations of the formation of Milky Way-mass galaxies identified to have a prominent radially anisotropic stellar halo compo…
