Galaxy sizes in the early Universe

P. Cataldi, S. Pedrosa, L. J. Pellizza +2

We present preliminary results of a study of galaxy sizes at redshift using the high-resolution, zoom-in \textsc{FirstLight} simulations. We obtain a redshift-indepen…

Angular momentum evolution in the CIELO simulations. I. Temporal evolution of gas-stellar misalignments and baryonic merger timing

Catalina Casanueva-Villarreal, Patricia B. Tissera, Nelson Padilla +4

Gas-stellar kinematic misalignments trace how galaxies assemble and reorient their angular momentum. Although well documented locally, their continuous evolution remains largely un…

The connection between surface brightness and satellite systems for central galaxies through Illustris TNG

Silvio Rodriguez, Yamila Yaryura, Jose A. Benavides +7

We analyse different properties of central low-surface-brightness galaxies (LSBGs) and their satellite systems using the simulation Illustris TNG-100, in order to deepen our unders…

Mass density structuring around galaxy formation sites: impact on galaxy basic properties

Sandra Robles, Rosa Domínguez-Tenreiro, Susana E. Pedrosa

We study the local evolution of the Universe around galaxy formation sites in the EAGLE50 large-volume reference simulation. Using the reduced inertia tensor (r-TOI), we followed t…

Galaxy sizes and compactness at Cosmic Dawn

P. Cataldi, S. Pedrosa, L. J. Pellizza +2

The James Webb Space Telescope has found an unexpected population of high-mass galaxies () with extremely small effective radii ($\sim 1…

Impact of Primordial Black Hole Dark Matter on Gas Properties at Very High Redshift: A Semi-Analytical Model

C. Casanueva-Villarreal, P. B. Tissera, N. Padilla +5

Context. Primordial black holes (PBHs) have been proposed as potential candidates for dark matter (DM) and have garnered significant attention in recent years. Aims. Our objective…
