NANCY: Next-generation All-sky Near-infrared Community surveY

Jiwon Jesse Han, Arjun Dey, Adrian M. Price-Whelan +206

The Nancy Grace Roman Space Telescope is capable of delivering an unprecedented all-sky, high-spatial resolution, multi-epoch infrared map to the astronomical community. This oppor…

Mapping the Distant and Metal-Poor Milky Way with SDSS-V

Vedant Chandra, Phillip A. Cargile, Alexander P. Ji +28

The fifth-generation Sloan Digital Sky Survey (SDSS-V) is conducting the first all-sky low-resolution spectroscopic survey of the Milky Way's stellar halo. We describe the stellar…

Age-Dating Red Giant Stars Associated with Galactic Disk and Halo Substructures

Samuel K. Grunblatt, Joel C. Zinn, Adrian M. Price-Whelan +12

The vast majority of Milky Way stellar halo stars were likely accreted from a small number (3) of relatively large dwarf galaxy accretion events. However, the timing of t…

All-Sky Kinematics of the Distant Halo: The Reflex Response to the LMC

Vedant Chandra, Rohan P. Naidu, Charlie Conroy +11

The infall of the Large Magellanic Cloud (LMC) is predicted to displace the inner Milky Way (MW), imprinting an apparent 'reflex motion' on the observed velocities of distant halo…

Kinematic Signatures in the Stellar Halo from Cosmological Encounters between the Milky Way and its Clouds

Mia Mansfield, Robyn Sanderson, Daniel Hey +4

Recent theoretical and observational analysis of the interaction between the Milky Way (MW) and LMC suggest that it has a significant dynamical impact on the MW's stellar halo. We…

Orientations of DM Halos in FIRE-2 Milky Way-mass Galaxies

Jay Baptista, Robyn Sanderson, Dan Huber +11

The shape and orientation of dark matter (DM) halos are sensitive to the micro-physics of the DM particle, yet in many mass models, the symmetry axes of the Milky Way's DM halo are…
