Phase-Spirals Across Galactic Disks II: Using large-scale "macro-spirals" in phase-spiral amplitude to derive perturbation times
Kiyan Tavangar, Kathryn V. Johnston, Jason A. S. Hunt +3
Phase-space spirals in the Milky Way disk are a key observable remnant of recent perturbations to the Galaxy. They provide insight into the disk's potential, dynamical evolution, p…
The DECam MAGIC Survey Mapping the Ancient Galaxy in CaHK: Overview and Summary of Early Science
A. Chiti, A. Drlica-Wagner, A. B. Pace +42
We present the DECam Mapping the Ancient Galaxy in CaHK (MAGIC) survey, a 54-night NOIRLab Survey Program to image 5,000deg of the southern hemisphere using a meta…
Phase spirals across galactic disks I: Exploring dynamical influences on winding
Kiyan Tavangar, Kathryn V. Johnston, Jason A. S. Hunt +4
The vertical phase-space spirals in the Milky Way are clear evidence of disequilibrium. However, they are challenging to study because phase mixing signals evolve under the influen…
A near field guide to Roman's wide-area surveys
Robyn E. Sanderson, Kevin A. McKinnon, Adrien C. R. Thob +7
The Nancy Grace Roman Space Telescope currently plans to survey nearly 6000 square degrees of the sky, mainly in the High-Latitude Wide-Area Survey (HLWAS) and Galactic Plane Surve…
Winding, Unwinding, Rewinding the Gaia Phase Spiral
Neige Frankel, Marcin Semczuk, Teresa Antoja +10
The Gaia Space Satellite has transformed the field of Galactic Dynamics by collecting 6D phase space information for hundreds of millions of stars. In 2018, it enabled the discover…
