Galaxy pairs in the Sloan Digital Sky Survey -- XIV. Galaxy mergers do not lie on the Fundamental Metallicity Relation
Sebastián Bustamante, Sara L. Ellison, David R. Patton +1
In recent observational studies, star-forming galaxies have been shown to follow a relation often dubbed the fundamental metallicity relation (FMR). This relation links the stellar…
Spin evolution and feedback of supermassive black holes in cosmological simulations
Sebastian Bustamante, Volker Springel
It is well established that the properties of supermassive black holes and their host galaxies are correlated through scaling relations. While hydrodynamical cosmological simulatio…
The Auriga Stellar Haloes: Connecting stellar population properties with accretion and merging history
Antonela Monachesi, Facundo A. Gómez, Robert J. J. Grand +9
We examine the stellar haloes of the Auriga simulations, a suite of thirty cosmological magneto-hydrodynamical high-resolution simulations of Milky Way-mass galaxies performed with…
Merger-Induced Metallicity Dilution in Cosmological Galaxy Formation Simulations
Sebastian Bustamante, Martin Sparre, Volker Springel +1
Observational studies have revealed that galaxy pairs tend to have lower gas-phase metallicity than isolated galaxies. This metallicity deficiency can be caused by inflows of low-m…
Origin of chemically distinct discs in the Auriga cosmological simulations
Robert J. J. Grand, Sebastián Bustamante, Facundo A. Gómez +7
The stellar disk of the Milky Way shows complex spatial and abundance structure that is central to understanding the key physical mechanisms responsible for shaping our Galaxy. In…
Lessons from the Auriga discs: The hunt for the Milky Way's ex-situ disc is not yet over
Facundo A. Gómez, Robert J. J. Grand, Antonela Monachesi +7
We characterize the contribution from accreted material to the galactic discs of the Auriga Project, a set of high resolution magnetohydrodynamic cosmological simulations of late-t…
Magnetic properties of Proxima Centauri b analogues
Jorge I. Zuluaga, Sebastian Bustamante
The discovery of a planet around the closest star to our Sun, Proxima Centauri, represents a quantum leap in the testability of exoplanetary models. Unlike any other discovered exo…
Tensor anisotropy as a tracer of cosmic voids
Sebastian Bustamante, Jaime E. Forero-Romero
We present a new method to find voids in cosmological simulations based on the tidal and the velocity shear tensors definitions of the cosmic web. We use the fractional anisotropy…
The Influence of Thermal Evolution in the Magnetic Protection of Terrestrial Planets
Jorge I. Zuluaga, Sebastian Bustamante, Pablo A. Cuartas +1
Magnetic protection of potentially habitable planets plays a central role in determining their actual habitability and/or the chances of detecting atmospheric biosignatures. We dev…
The kinematics of the Local Group in a cosmological context
Jaime E. Forero-Romero, Yehuda Hoffman, Sebastian Bustamante +2
Recent observations constrained the tangential velocity of M31 with respect to the Milky Way (MW) to be v_tan<34.4 km/s and the radial velocity to be in the range v_rad=-109+/- 4.4…
