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…
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…
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…
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…
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…
Leo I: the classical dwarf spheroidal galaxy with the highest dark-matter density
R. Pascale, C. Nipoti, F. Calura +1
Dwarf spheroidal galaxies (dSphs) are known for being strongly dominated by dark matter (DM), which makes them convenient targets for investigating the DM nature and distribution.…
Chemo-dynamics of the stellar component of the Sculptor dwarf galaxy II: dynamical properties and dark matter halo density
José María Arroyo Polonio, Raffaele Pascale, Giuseppina Battaglia +4
Dwarf galaxies satellite of the Milky Way are excellent laboratories for testing dark matter (DM) models and baryonic feedback implementation in simulations. The Sculptor 'classica…
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…
Evolution of massive quiescent galaxies via envelope accretion
Carlo Nipoti
Massive quiescent galaxies at high redshift are significantly more compact than their present-day counterparts. We investigate the roles, in determining this evolution, of major an…
Chemo-dynamics of the stellar component of the Sculptor dwarf galaxy I: observed properties
José María Arroyo-Polonio, Giuseppina Battaglia, Guillaume F. Thomas +3
Aims. Recently, both the presence of multiple stellar chemo-kinematic components and rotation in the Sculptor dwarf spheroidal galaxy have been put into question. Therefore, we re-…
Dark-matter central density, annihilation J-factor and decay D-factor of the Fornax, Sculptor and Leo I dwarf spheroidal galaxies
Carlo Nipoti, Raffaele Pascale, José María Arroyo-Polonio
The dwarf spheroidal galaxies (dSphs) satellites of the Milky Way (MW) are nearby astrophysical laboratories to study the nature of dark matter (DM). We present some properties of…
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…
Old massive clusters (and a nuclear star cluster?) in the tidal tails of NGC5238
M. Bellazzini, F. Annibali, M. Correnti +12
New, deep HST photometry allowed us to identify and study eight compact and bright (M_V< -5.8) star clusters in the outskirts of the star-forming isolated dwarf galaxy NGC5238 (M_*…
Tidal mass loss in the Fornax dwarf spheroidal galaxy through N-body simulations with Gaia DR3-based orbits
Pierfrancesco Di Cintio, Giuliano Iorio, Francesco Calura +2
The Fornax dwarf spheroidal galaxy (dSph) represents a challenge for some globular cluster (GC) formation models, because an exceptionally high fraction of its stellar mass is lock…
