SAMI and TNG-Cluster: tracing galaxy spin and environmental transformation across cluster phase-space and cosmic time
Gustavo F. Gonçalves, Ilaria Marini, A. Fraser-McKelvie +4
The dense environment of galaxy clusters suppresses star formation and alters the kinematic properties of infalling satellites through gas stripping, tidal interactions, gravitatio…
Circumgalactic medium depletion drives satellite quenching in IllustrisTNG
Natan de Isídio, Paola Popesso, Sandro Tacchella +5
Satellite galaxies dominate the quenched population at low stellar masses (), yet identifying which processes shut down their star formation,…
What's Missing in AGN Feedback? Lessons learnt from Magneticum, IllustrisTNG and Simba
D. T. Mazengo, P. Popesso, I. Marini +20
Accurately balancing gas reservoirs, star formation, and feedback across cosmic time remains a central challenge for galaxy formation models in modern hydrodynamical simulations. W…
Baryonic assembly bias in X-ray-selected galaxy groups and clusters: insights from the Magneticum simulation
Ilaria Marini, Tiago Castro, Paola Popesso +5
Galaxy groups and clusters trace the large-scale matter distribution, with their clustering usually interpreted mainly as a function of halo mass. Yet, at fixed mass, their baryoni…
The kinematic imprinting of environmental quenching in galaxies
Natan de Isídio, P. Popesso, Y. Bahé +9
We present the first systematic census of quenching mechanisms using kinematic asymmetries in a large sample of 6,700 galaxies from the MaNGA survey, providing a unified view…
The stellar-to-halo mass relation of central galaxies across three orders of halo mass
Victoria Toptun, Paola Popesso, Ilaria Marini +9
The stellar content of galaxies is tightly connected to the mass and growth of their host dark matter halos. Observational constraints on this relation remain limited, particularly…
The eROSITA view on the halo mass-temperature relation: From low-mass groups to massive clusters
V. Toptun, P. Popesso, I. Marini +15
Galaxy groups and clusters are among the best probes of structure formation and growth in a cosmological context. Most of their baryonic component is dominated by the intracluster…
The impact of assembly history on the X-ray detectability of halos. From galaxy groups to galaxy clusters
I. Marini, P. Popesso, K. Dolag +15
Galaxy groups represent a significant fraction of the halo population, playing a crucial role in galaxy formation and evolution. However, their detection in X-rays remains challeng…
Average X-ray properties of galaxy groups. From Milky Way-like halos to massive clusters
P. Popesso, I. Marini, K. Dolag +20
This study examines the average X-ray properties of massive halos at z< 0.2, covering the largest halo mass range to date, from Milky Way-like halos to massive clusters. The analys…
The hot gas mass fraction in halos. From Milky Way-like groups to massive clusters
P. Popesso, A. Biviano, I. Marini +21
By using eROSITA data in the eFEDS area, we provide a measure of the hot gas fraction vs. halo mass relation over the largest halo mass range, from Milky Way-sized halos to massive…
The perils of stacking optically selected groups in eROSITA data. The Magneticum perspective
P. Popesso, I. Marini, K. Dolag +23
Hydrodynamical simulation predictions are often compared with observational data without fully accounting for systematics and biases specific to observational techniques. Using the…
Detecting clusters and groups of galaxies populating the local Universe in large optical spectroscopic surveys
I. Marini, P. Popesso, K. Dolag +13
Wide-field cosmological surveys provide hundreds of thousands of spectroscopically confirmed galaxy groups and clusters, valuable for tracing baryonic matter distribution. However,…
