Tracing the very early disruption of the Sagittarius dwarf galaxy in the distant Milky Way halo
Manuel Bayer, Else Starkenburg, Akshara Viswanathan +3
Current models predict that at distances beyond 80 kpc in the Milky Way halo, we can find the earliest escaped stars from the merging Sagittarius dwarf galaxy. However, observation…
Reconstructing the orbits of Milky Way dwarf galaxies: A Large Magellanic Cloud perspective
Alberto Manuel Martínez-García, Andrés del Pino, Roeland P. van der Marel +14
The orbital histories of the dwarf satellites of the Milky Way (MW) are key to understanding their evolution and placing their present-day properties in a dynamical context. We pre…
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…
Systematic census of RR Lyrae stars in Milky Way stellar streams
Bruno Domínguez, Cecilia Mateu, Pau Ramos +1
Context. Nearly 150 tidal streams are known in the Milky Way, but full phase-space information exists for only a few. RR Lyrae stars (RRL), as standard candles, provide a powerful…
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…
A non-axisymmetric potential for the Milky Way disk
Y. R. Khalil, B. Famaey, G. Monari +9
We provide a purely dynamical global map of the non-axisymmetric structure of the Milky Way disk. For this, we exploit the information contained within the in-plane motions of disk…
Segue 2 Recently Collided with the Cetus-Palca Stream: New Opportunities to Constrain Dark Matter in an Ultra-Faint Dwarf
Hayden R. Foote, Gurtina Besla, Nicolás Garavito-Camargo +7
Stellar streams in the Milky Way are promising detectors of low-mass dark matter (DM) subhalos predicted by CDM. Passing subhalos induce perturbations in streams that indicate t…
A Bayesian estimation of the Milky Way's circular velocity curve using Gaia DR3
Sven Põder, María Benito, Joosep Pata +5
Our goal is to calculate the circular velocity curve of the Milky Way, along with corresponding uncertainties that quantify various sources of systematic uncertainty in a self-cons…
