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…

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…

Where Have All the Little Red Dots Gone? Supermassive Black Hole Binary Dynamics and its Impact on Galaxy Properties

Fazeel Mahmood Khan, Benjamin L. Davis, Andrea Valerio Macciò +1

Recent James Webb Space Telescope observations have revealed a peculiar class of galaxies at redshifts , characterized by extremely high central stellar densities and…

Gas accretion at high redshift: cold flows all the way

Stefan Waterval, Carlo Cannarozzo, Andrea V. Macciò

We study in detail how massive galaxies accrete gas through cosmic time using cosmological hydrodynamical simulations from the High-z Evolution of Large and Luminous Objects (HELLO…

Fuzzy Gasoline: Cosmological hydrodynamical simulations of dwarf galaxy formation with Fuzzy Dark Matter

Matteo Nori, Shubhan Bhatia, Andrea V. Macciò

We present the first set of high-resolution, hydrodynamical cosmological simulations of galaxy formation in a Fuzzy Dark Matter (FDM) framework. These simulations were performed wi…

HELLO project: High- Evolution of Large and Luminous Objects

Stefan Waterval, Andrea V. Macciò, Tobias Buck +6

We present the High- Evolution of Large and Luminous Objects (HELLO) project, a set of high-resolution cosmological simulations aimed to study Milky Way analogues ($M…
