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…
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…
-ray detection from occasional flares in T Tauri stars of NGC 2071. I. Observational connection
A. Filócomo, J. F. Albacete Colombo, E. Mestre +2
NGC 2071 is a star-forming region that overlaps with three -ray sources detected by the Fermi Space Telescope. We propose that strong flare activity in T Tauri stars could produ…
Redshift evolution of the dark matter haloes shapes
Pedro Cataldi, Susana Pedrosa, Patricia Tissera +6
In this work, we aim at investigating the morphology evolution of Milky Way mass-like dark matter haloes selected from the CIELO and IllustrisTNG Projects. The connection between h…
Highly collimated microquasar jets as efficient cosmic-ray sources
G. J. Escobar, L. J. Pellizza, G. E. Romero
Supernova remnants are believed to be the main sites where Galactic cosmic rays originate. This scenario, however, fails to explain some of the features observed in the cosmic-ray…
Exploring the physics behind the non-thermal emission from star-forming galaxies detected in gamma rays
P. Kornecki, E. Peretti, S. del Palacio +2
Star-forming galaxies (SFGs) emit non-thermal radiation from radio to gamma-rays. We aim to investigate the main mechanisms of global CR transport and cooling in SFGs. The way they…
