Multi-component, axisymmetric dynamical models of dSphs based on distribution functions: inferences on dark matter and intermediate-mass black holes in Draco and Ursa Minor
R. Pascale, G. Battaglia, J. M. Arroyo-Polonio +3
Dwarf spheroidal galaxies (dSphs) are prime laboratories for studying dark matter (DM) and the black hole demographics in the low-mass regime. These systems are also often flattene…
Gas rotation and turbulence in the galaxy cluster Abell 2029
T. Bartalesi, A. Simionescu, S. Ettori +4
We constrain the rotation and turbulent support of the intracluster medium (ICM) in Abell 2029 (A2029), using dynamical equilibrium models and a combination of state-of-the-art X-r…
Death by Impact: Evidence for Merger-Driven Quenching in a Collisional Ring Galaxy at Cosmic Noon
Amir H. Khoram, Sirio Belli, Carlo Nipoti +7
The role of interactions and mergers in the rapid quenching of massive galaxies in the early Universe remains uncertain, largely due to the difficulty of directly linking mergers t…
Type Ia supernova feedback effects on globular clusters of different masses
E. Lacchin, M. Donati, F. Calura +3
Through 3D hydrodynamical simulations, we explore the impact of Type Ia supernova (SN) explosions on the star formation history and chemical properties of second-generation (SG) st…
Dynamical mirages: how bar-induced resonant trapping can mimic substructure clustering in dynamical parameter spaces
Michele De Leo, Davide Massari, Michele Bellazzini +3
The complex task of unraveling the assembly history of the Milky Way is in constant evolution with new substructures identified continuously. To properly validate and characterise…
Mass loss and dynamical friction on the Fornax dSph galaxy in the Milky Way potential
Pierfrancesco Di Cintio, Giuliano Iorio, Carlo Nipoti +1
We study the interplay between mass-loss and dynamical friction (DF) on the orbital decay of the Fornax dwarf spheroidal galaxy in the potential of the Milky Way (MW). Using a simp…
