Optical Spectroscopy of a Candidate O-Star X-ray Binary in M33
Margaret Lazzarini, Lara Cullinane, Karoline Gilbert +8
We present new observations of a candidate O-type donor star in a high mass X-ray binary (HMXB) in M33. The candidate donor star is spatially coincident with a hard X-ray point sou…
Automated Computer Vision Cluster Identification in the Fireworks Galaxy
Debby Tran, Benjamin F. Williams, Emily M. Levesque +5
We present the integrated photometry, radii, and spatial distribution of young ( 25 Myr) star cluster candidates in NGC 6946. NGC 6946, also known as the Fireworks Galaxy, is…
A Multiwavelength Inventory for the Local Group L-band Survey I: Atlas and Radial Profiles of Local Group Galaxies
Cosima Eibensteiner, Adam K. Leroy, Jiayi Sun +21
Resolving atomic gas at pc physical resolution is currently feasible only for the very nearest galaxies. We combine 120 pc resolution HI data using the Karl G. Jansky…
Searching for Stellar Activity Cycles using Flares II: The TESS CVZ
Tobin M. Wainer, Holland M. Stuart, Guadalupe Tovar Mendoza +3
Magnetic activity cycles provide a fundamental constraint on stellar dynamos, but remain difficult to identify beyond the Sun. However, recent studies have shown that flares offer…
The Panchromatic Hubble Andromeda Southern Treasury (PHAST). II. The Spatially Resolved Recent Star Formation History in M31
Tobin M. Wainer, Benjamin F. Williams, Zhuo Chen +19
We use Hubble Space Telescope optical imaging from the Panchromatic Hubble Andromeda Southern Treasury (PHAST) to measure the spatially resolved recent star formation history (SFH)…
The Timescales of Embedded Star Formation as Observed in STARFORGE
Tobin M. Wainer, Julianne J. Dalcanton, Michael Y. Grudić +7
Star formation occurs within dusty molecular clouds that are then disrupted by stellar feedback. However, the timing and physical mechanisms that govern the transition from deeply…
Crowded Field Photometry with Rubin: Exploring 47 Tucanae with Data Preview 1
Tobin M. Wainer, James R. A. Davenport, Eric C. Bellm +15
We analyze imaging from Data Preview 1 of the Vera C. Rubin Observatory to explore the performance of early LSST pipelines in the 47 Tucanae field. The coadd-\texttt{object} catalo…
Optical Counterparts to X-ray sources in LSST DP1
Yuankun, Wang, Eric C. Bellm +9
We present a crossmatch between a combined catalog of X-ray sources and the Vera C. Rubin Observatory Data Preview 1 (DP1) to identify optical counterparts. The six fields targeted…
Searching for Stellar Activity Cycles using Flares: The Short and Long Timescale Activity Variations of TIC-272272592
Tobin M. Wainer, James R. A. Davenport, Guadalupe Tovar Mendoza +2
We examine 4 years of Kepler 30-min data, and 5 Sectors of TESS 2-min data for the dM3 star KIC-8507979/TIC-272272592. This rapidly rotating (P=1.2 day) star has previously been id…
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…
JWST Reveals Star Formation Across a Spiral Arm in M33
J. Peltonen, Erik Rosolowsky, Thomas G. Williams +13
Young stellar objects (YSOs) are the gold standard for tracing star formation in galaxies but have been unobservable beyond the Milky Way and Magellanic Clouds. But that all change…
Catalog of Integrated-Light Star Cluster Light Curves in TESS
Tobin M. Wainer, Gail Zasowski, Joshua Pepper +10
We present the first integrated light, TESS-based light curves for star clusters in the Milky Way, Small Magellanic Cloud, and Large Magellanic Cloud. We explore the information en…
Clusters, Clouds, and Correlations: Relating Young Clusters to Giant Molecular Clouds in M33 and M31
J. Peltonen, Erik Rosolowsky, L. Clifton Johnson +11
We use young clusters and giant molecular clouds (GMCs) in the galaxies M33 and M31 to constrain temporal and spatial scales in the star formation process. In M33, we compare the P…
The Chemodynamics of the Stellar Populations in M31 from APOGEE Integrated Light Spectroscopy
Benjamin J. Gibson, Gail Zasowski, Anil Seth +8
We present analysis of nearly 1,000 near-infrared, integrated light spectra from APOGEE in the inner 7 kpc of M31. We utilize full spectrum fitting with A-LIST simple stellar…
The Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER). IV. Star Cluster Catalog
L. Clifton Johnson, Tobin M. Wainer, Estephani E. TorresVillanueva +9
We construct a catalog of star clusters from Hubble Space Telescope images of the inner disk of the Triangulum Galaxy (M33) using image classifications collected by the Local Group…
The Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER). III. The Mass Function of Young Star Clusters in M33
Tobin M. Wainer, L. Clifton Johnson, Anil C. Seth +6
We measure the star cluster mass function for the Local Group galaxy M33. We use the catalog of stellar clusters selected from the Panchromatic Hubble Andromeda Treasury: Triangulu…
