Dark matter density profiles of the Milky Way satellite population: reconciling simulations and observations
Jorge Sarrato-Alós, José María Arroyo-Polonio
The cusp-core problem remains a key challenge for the CDM model. Historically, comparing inner dark matter halo slopes () from simulations and observations has s…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
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…
Estimating the dynamical masses of dwarf galaxies in the presence of binary-star contamination
José María Arroyo-Polonio, Giuseppina Battaglia, Guillaume F. Thomas
Ultra-faint dwarf galaxies (UFDs) show extreme dynamical mass-to-light ratios of approximately 100-5000 in solar units within the half-light radius, making them critical tests for…
Carbon measurements in two ultra-faint dwarf galaxies: Grus II and Tucana IV
Valentina Verdiani, Ása Skúladóttir, Romain Lucchesi +7
The ultra-faint dwarf galaxies (UFDs) are some of the oldest and most metal-poor environments in the Local Group. In particular, they are predicted to host the first stars (only H…
A 3D view of dwarf galaxies with Gaia and VLT/FLAMES II. The Sextans dwarf spheroidal
Eline Tolstoy, Giuseppina Battaglia, José María Arroyo-Polonio +7
The Sextans dwarf spheroidal galaxy has been challenging to study in a comprehensive way as it is highly extended on the sky, with an uncertain but large tidal radius of between 80…
