Satellites Around Milky Way Analogs: Tension in the Number and Fraction of Quiescent Satellites Seen in Observations Versus Simulations

We compare the star-forming properties of satellites around Milky Way (MW) analogs from the Stage~II release of the Satellites Around Galactic Analogs Survey (SAGA-II) to those fro…
Linking the brightest stellar streams with the accretion history of Milky Way-like galaxies
Alex Vera-Casanova, Facundo A. Gómez, Antonela Monachesi +8
According to the current galaxy formation paradigm, mergers and interactions play an important role in shaping present-day galaxies. The remnants of this merger activity can be use…
Determining the full satellite population of a Milky Way-mass halo in a highly resolved cosmological hydrodynamic simulation

Cristian A. Vega-Martínez, Facundo A. Gómez, Sofía A. Cora +1
We present a new analytic fitting profile to model the ram pressure exerted over satellite galaxies on different environments and epochs. The profile is built using the information…
Too dense to go through: The importance of low-mass clusters for satellite quenching

We study the evolution of satellite galaxies in clusters of the \textsc{c-eagle} simulations, a suite of 30 high-resolution cosmological hydrodynamical zoom-in simulations based on…
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…
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)…
The Orbital Histories of Magellanic Satellites Using Gaia DR2 Proper Motions
Ekta Patel, Nitya Kallivayalil, Nicolas Garavito-Camargo +6
With the release of Gaia DR2, it is now possible to measure the proper motions (PMs) of the lowest mass, ultra-faint satellite galaxies in the Milky Way's (MW) halo for the first t…
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…
