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…
Beyond the surface: hydrodynamical N-body simulations of the interacting dwarf galaxies NGC 5238 and UGC 8760
R. Pascale, F. Annibali, M. Tosi +6
From deep imaging data obtained with the Large Binocular Telescope as part of the Smallest Scale of Hierarchy Survey (SSH), we have discovered low-surface brightness tidal features…
The central black hole in the dwarf spheroidal galaxy Leo I Not supermassive, at most an intermediate-mass candidate
R. Pascale, C. Nipoti, F. Calura +1
It has been recently claimed that a surprisingly massive black hole (BH) is present in the core of the dwarf spheroidal galaxy (dSph) Leo I. Based on integral field spectroscopy, t…
