Panchromatic Hubble Andromeda Treasury. XIX. The Ancient Star Formation History of the M31 Disk
Benjamin F. Williams, Andrew E. Dolphin, Julianne J. Dalcanton +7
We map the star formation history across M31 by fitting stellar evolution models to color-magnitude diagrams of each 8383 (0.31.4 kpc, deprojected) region o…
The Panchromatic Hubble Andromeda Treasury XI: The Spatially-Resolved Recent Star Formation History of M31
Alexia R. Lewis, Andrew E. Dolphin, Julianne J. Dalcanton +15
We measure the recent star formation history (SFH) across M31 using optical images taken with the \texit{Hubble Space Telescope} as part of the Panchromatic Hubble Andromeda Treasu…
A Global Star Forming Episode in M31 2-4 Gyr Ago
Benjamin F. Williams, Julianne J. Dalcanton, Andrew E. Dolphin +9
We have identified a major global enhancement of star formation in the inner M31 disk that occurred between 2-4 Gyr ago, producing 60% of the stellar mass formed in the past…
The High-Mass Stellar Initial Mass Function in M31 Clusters
Daniel R. Weisz, L. Clifton Johnson, Daniel Foreman-Mackey +16
We have undertaken the largest systematic study of the high-mass stellar initial mass function (IMF) to date using the optical color-magnitude diagrams (CMDs) of 85 resolved, young…
A clear age-velocity dispersion correlation in Andromeda's stellar disk
Claire E. Dorman, Puragra Guhathakurta, Anil C. Seth +9
The stellar kinematics of galactic disks are key to constraining disk formation and evolution processes. In this paper, for the first time, we measure the stellar age-velocity disp…
