Variability in Cosmological Hydrodynamical Simulations: how Stochastic Processes, Numerical Effects, and Reproducibility Limits impact Predictability
Chaitra, Antonio Ragagnin, Milena Valentini +3
Cosmological hydrodynamical simulations are powerful tools for studying galaxy formation, yet their predictive precision is limited by stochastic variability and numerical uncertai…
Novel insights into the Coma cluster kinematics with DESI. I. Linking mass profile, orbital anisotropy, and galaxy populations
S. Pedratti, L. Pizzuti, M. Fossati +4
We investigate the kinematic properties of the Coma galaxy cluster using a new, large spectroscopic sample of member galaxies, from the Dark Energy Spectroscopic Instrument (DESI).…
The dynamical evolution of the stellar clumps in the Sparkler galaxy
Eric Giunchi, Federico Marinacci, Carlo Nipoti +4
Recent JWST observations detected stellar clumps around the z=1.4 gravitationally lensed Sparkler galaxy (of stellar mass ), with ages and metallici…
SIEGE IV: compact star clusters in cosmological simulations with high star formation efficiency and sub-parsec resolution
R. Pascale, F. Calura, E. Vesperini +10
The formation of compact high-redshift star-forming clumps, the physical processes driving their evolution and their potential connection to present-day Globular Clusters are key o…
SIEGE III: The formation of dense stellar clusters in sub-parsec resolution cosmological simulations with individual star feedback
F. Calura, R. Pascale, O. Agertz +10
Star clusters stand at the crossroads between galaxies and single stars. Resolving the formation of star clusters in cosmological simulations represents an ambitious and challengin…
Exploring the low-mass regime of galaxy-scale strong lensing: Insights into the mass structure of cluster galaxies
Giovanni Granata, Pietro Bergamini, Claudio Grillo +8
We aim at a direct measurement of the compactness of three galaxy-scale lenses in massive clusters, testing the accuracy of the scaling laws that describe the members in strong len…
The Three Hundred: relation
Atulit Srivastava, Weiguang Cui, Massimo Meneghetti +8
In this study, we investigate a recent finding based on strong lensing observations, which suggests that the sub-halos observed in clusters exhibit greater compactness compared to…
Impact of H-driven star formation and stellar feedback from low-enrichment environments on the formation of spiral galaxies
Milena Valentini, Klaus Dolag, Stefano Borgani +8
The reservoir of molecular gas (H) represents the fuel for the star formation (SF) of a galaxy. Connecting the star formation rate (SFR) to the available H is k…
Mapping "out-of-the-box" the properties of the baryons in massive halos
M. Angelinelli, S. Ettori, K. Dolag +2
We study the distributions of the baryons in massive halos () in the suite of Smoothed Particle Hydrodynamical cosmological simula…
Velocity dispersion of the brightest cluster galaxies in cosmological simulations
I. Marini, S. Borgani, A. Saro +7
Using the DIANOGA hydrodynamical zoom-in simulation set of galaxy clusters, we analyze the dynamics traced by stars belonging to the Brightest Cluster Galaxies (BCGs) and their sur…
The DIANOGA simulations of galaxy clusters: characterizing star formation in proto-clusters
L. Bassini, E. Rasia, S. Borgani +11
We studied the star formation rate (SFR) in cosmological hydrodynamical simulations of galaxy (proto-)clusters in the redshift range , comparing them to recent observational…
Galactic outflow and diffuse gas properties at z>=1 using different baryonic feedback models
Paramita Barai, Pierluigi Monaco, Giuseppe Murante +2
We measure and quantify properties of galactic outflows and diffuse gas at in cosmological hydrodynamical simulations. Our novel sub-resolution model, MUPPI, implements…
