A Timeline of the M81 Group: Properties of the Extended Structures of M82 and NGC 3077
Benjamin N. Velguth, Eric F. Bell, Adam Smercina +8
Mergers of and interactions between galaxies imprint a wide diversity of morphological, dynamical, and chemical characteristics in stellar halos and tidal streams. Measuring these…
The Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER). VI. The High-Mass Stellar Initial Mass Function of M33
Tobin M. Wainer, Benjamin F. Williams, L. Clifton Johnson +15
We measure the high-mass stellar initial mass function (IMF) from resolved stars in M33 young stellar clusters. Leveraging \textit{Hubble Space Telescope's} high resolving power, w…
TREX: Kinematic Characterisation of a High-Dispersion Intermediate-Age Stellar Component in M33
L. R. Cullinane, Karoline M. Gilbert, Puragra Guhathakurta +7
The dwarf galaxy Triangulum (M33) presents an interesting testbed for studying stellar halo formation: it is sufficiently massive so as to have likely accreted smaller satellites,…
The Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER). V. The Structure of M33 in Resolved Stellar Populations
Adam Smercina, Julianne J. Dalcanton, Benjamin F. Williams +13
We present a detailed analysis of the the structure of the Local Group flocculent spiral galaxy M33, as measured using the Panchromatic Hubble Andromeda Treasury Triangulum Extende…
Constraining the assembly time of the stellar haloes of nearby Milky Way-mass galaxies through AGB populations
Benjamin Harmsen, Eric F. Bell, Richard D'Souza +5
The star formation histories (SFHs) of galactic stellar haloes offer crucial insights into the merger history of the galaxy and the effects of those mergers on their hosts. Such me…
The Panchromatic Hubble Andromeda Treasury XXI. The Legacy Resolved Stellar Photometry Catalog
Benjamin F. Williams, Meredith Durbin, Dustin Lang +14
We present the final legacy version of stellar photometry for the Panchromatic Hubble Andromeda Treasury (PHAT) survey. We have reprocessed all of the Hubble Space Telescope (HST)…
