I will describe the activity aimed at characterising AGN through their variability in preparation for next generation LSST surveys.
The purpose of this work is to understand if, among the blazars not detected by Fermi-LAT, a population of TeV emitting sources could be detected by current or future Cherenkov telescopes. We cross-matched the 5BZCAT catalog of blazars with the most recent catalogs of point-like source, to determine if the X-ray emission can be used as an effective proxy to find and characterize candidate...
I will talk about the recent discoveries on high redshift galaxies made by JWST in the last year, and what we can expect from the next rounds of observations.
The recent data by the JWST satellite identify what seems an excess of luminous objects in the early Universe. It has been proposed that this may be evidence that exotic monsters lurk in the cosmic Dark Ages.
I will show how -while such excesses seems to be consistent and real- they can not be explained by some of the most extreme versions of "dark matter supported stellar objects" that myself...
I will present a project collecting machine learning tools to extract physical parameters from the major sky surveys and predict the cosmological parameters using million to billion galaxy samples.
Nel paradigma della Relatività Generale, l'attrazione gravitazionale è un fenomeno geometrico dello spaziotempo avvertito tanto dai corpi massivi che dai campi puramente energetici, come il campo elettromagnetico. In quest'ottica, anche il concetto di peso cambia, perchè non dipende solo dalla quantità di materia ma anche dall'energia interna. Trattandosi di una teoria classica, si ritiene...
The DarkSide-20k is a 20-tonne fiducial mass dual phase Liquid Argon Time Projection Chamber (LArTPC) detector for the direct dark matter search, filled with low radioactivity Argon and equipped with customised cryogenic SiPM photosensors. The experiment will be constructed in INFN Gran Sasso underground Laboratory (LNGS), and is expected to be free of any instrumental background for an...
With the increasing precision of experimental measurements in collider physics, testing the Standard Model requires ever more accurate theoretical predictions. LINE is a software designed to contribute to this goal by addressing the numerical computation of multi-loop Feynman integrals solving differential equations via series expansion. The code is written in C to efficiently leverage...
