CRIMSONS: An Online Tool for Modeling Chemical Enrichment with Stochastic IMF Sampling

Martina Rossi, Lapo Querci, Stefano Ciabattini +14

Chemical enrichment is a universal process shaped by several interconnected factors, including stellar feedback, the nature of chemical polluters, and the underlying distribution o…

The solitary star cluster of the Andromeda XXV dwarf spheroidal

Chiara Crociati, Annette M. N. Ferguson, Gracie McGill +6

We present Hubble Space Telescope Advanced Camera for Surveys observations of Gep I, a globular cluster (GC) candidate in the low-mass ()…

Revisiting the enigmatic sixth star cluster in the Fornax dwarf spheroidal galaxy

Chiara Crociati, Annette M. N. Ferguson, Raffaele Pascale +7

The Fornax dwarf spheroidal (dSph) galaxy is one of only two Local Group dSphs that host a population of globular star clusters (GCs), the present-day properties of which have ofte…

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…

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…

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…

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…
