The NIVARIA-Local Group simulations: Unveiling the origin of rotation curve diversity in dwarf galaxies and its connection to galaxy morphology
A. Contreras-Santos, A. Di Cintio, A. Negri +7
Dwarf galaxies exhibit a large diversity in rotation curve shapes, challenging galaxy formation models within the CDM paradigm. We present NIVARIA-LG, a new suite of cosmologica…
Dark matter haloes from dwarf to massive galaxies: no systematic inner-density tension with ΛCDM hydrodynamical simulations
Pavel E. Mancera Piña, Justin I. Read, Jorge Sarrato-Alós +1
Two of the most prominent small-scale challenges to the cold dark matter (CDM) paradigm are the cusp-core and diversity-of-rotation-curves problems. The former concerns the shallow…
Dark matter density profiles of the Milky Way satellite population: reconciling simulations and observations
Jorge Sarrato-Alós, José María Arroyo-Polonio
The cusp-core problem remains a key challenge for the CDM model. Historically, comparing inner dark matter halo slopes () from simulations and observations has s…
The Impact of Star Formation Histories on the Inner Dark Matter Density Slopes of Galaxies
Jorge Sarrato-Alós, James Bullock, Arianna Di Cintio +3
Aims. We aim to investigate the connection between star formation histories (SFHs) and the inner dark matter density profiles of simulated galaxies. In particular, we test whether…
Beyond single tracers: CNN-based inference of galaxy mass profiles from combined gas and stellar kinematics
Julen Expósito-Márquez, Arianna Di Cintio, Chris Brook +2
We investigate whether combining gas and stellar kinematic maps provides measurable advantages in recovering galaxy mass profiles, compared to using single-component maps alone. Wh…
Galaxy mass profiles with convolutional neural networks
Jorge Sarrato-Alós, Christopher Brook, Arianna Di Cintio +3
Determining the dynamical mass profiles of dispersion-supported galaxies is particularly challenging due to projection effects and the unknown shape of their velocity anisotropy pr…
Constraining gas metal mixing strength in simulations using observations of the Milky Way's disc
Jorge Sarrato-Alós, Christopher Brook, Arianna Di Cintio
This work explores the mixing rate of metals in the interstellar medium (ISM), comparing observational constraints from our solar neighbourhood to high resolution cosmological hydr…
