Circumgalactic medium depletion drives satellite quenching in IllustrisTNG

Natan de Isídio, Natan de Isídio, Paola Popesso +6

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…
