Portrait of a Galaxy on FIRE: Is the -bimodality a natural consequence of inside-out disc growth in a hierarchical formation scenario?
MarÃa Benito, Annaliina Aavik, Giuseppina Battaglia +7
The chemical dichotomy in the [/Fe]-[Fe/H] plane is a consequence of the complex processes underlying the formation and evolution of disc galaxies such as observed in the stell…
Massive Star Population in the Sextans A Dwarf Galaxy from HST UV Photometry
Roberto Flores, Elena Fantino, Giuseppina Battaglia +1
We build a catalog of massive (M>M) main sequence stars in the \mbox{metal-poor} (Z) dwarf irregular galaxy Sextans A. HST WFC3 UV photometry in the 2…
Cored galaxies in cuspy dark matter halos
Fernando Valenciano, Jorge Martin Camalich, Arianna Di Cintio +4
We investigate constraints on the inner stellar density profile from photometric data of dwarf spheroidal and ultra-faint dwarf galaxies. Our aim is to clarify under what condition…
Local Group dwarf galaxies as dark matter probes
G. Battaglia, J. M. Arroyo Polonio, R. Pascale +3
Unveiling the fundamental nature of non-baryonic dark matter (DM) has profound implications for our understanding of the Universe and of the physical laws that govern it. Its manif…
Searching for Intermediate-Mass Black Holes in Milky Way satellites
R. Pascale, G. Battaglia
Intermediate-mass black holes (IMBHs), with masses between roughly and , represent a largely uncharted component of the black-hole (BH) population. T…
