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…

GALATEA: The 15-m Galactic Archaeology Spectroscopic Surveyor

Borja Anguiano, David Valls-Gabaud, Andrés del Pino +5

\textsc{GALATEA} (the \emph{Galactic Archaeology and Local-group Astrophysics Telescope for Extended Areas}) is a concept for a dedicated 15-m, wide-field, 10,000-fibre spectroscop…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Galactic Archaeology from the Northern Sky

Borja Anguiano, David Valls-Gabaud, Guillaume F. Thomas +7

By the 2040s--50s, facilities such as \emph{Gaia}, WEAVE, 4MOST, Rubin, \emph{Euclid}, \emph{Roman}, and the ESO ELT will have transformed our global view of the Milky Way. Yet key…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites

C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48

A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: A Low Surface Brightness Science Case

Mireia Montes, Ignacio Trujillo, David Martínez Delgado +27

The Extragalactic Low Surface Brightness (LSB, mag/arcsec) Universe represents a crucial, yet largely unseen, frontier in modern astrophysics. This faint realm…

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…
