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…
The M31-M33 Interaction: Impact on M31's Center of Mass Motion and Satellite Orbits
Ekta Patel, Nicolas Garavito-Camargo, Ivanna Escala
Inspired by recent studies of the Milky Way--LMC interaction and its implications for the Milky Way's global dynamical history, we investigate how the massive satellite galaxy M33…
Kinematical Modeling of the Resolved Stellar Outskirts of M32: Constraints on Tidal Stripping Scenarios
Ivanna Escala, Douglas Grion Filho, Puragra Guhathakurta +8
As the only compact elliptical close enough to resolve into individual stars, the satellite dwarf galaxy M32 provides a unique opportunity for exploring the origins of such rare ga…
