Monitoring the X-ray Variability of Bright X-ray Sources in M33
Rebecca Kyer, Shelby Albrecht, Benjamin F. Williams +8
We present a new five-epoch Chandra X-ray Observatory monitoring survey of the nearby spiral galaxy M33 which probes X-ray variability with time sampling between two weeks and four…
The High Energy X-ray Probe: Resolved X-ray Populations in Extragalactic Environments
Bret D. Lehmer, Kristen Garofali, Breanna A. Binder +15
We construct simulated galaxy data sets based on the High Energy X-ray Probe (HEX-P) mission concept to demonstrate the significant advances in galaxy science that will be yielded…
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…
Spatially-Resolved Recent Star Formation History in NGC 6946
Debby Tran, Benjamin Williams, Emily Levesque +6
The nearby face-on star forming spiral galaxy NGC 6946 is known as the Fireworks Galaxy due to its hosting an unusually large number of supernova. We analyze its resolved near-ultr…
Multiwavelength Characterization of the High Mass X-ray Binary Population of M33
Margaret Lazzarini, Kyros Hinton, Cheyanne Shariat +12
We present multi-wavelength characterization of 65 high mass X-ray binary (HMXB) candidates in M33. We use the Chandra ACIS survey of M33 (ChASeM33) catalog to select hard X-ray po…
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 Spatial Correlation of High Mass X-ray Binaries and Young Star Clusters in Nearby Star-Forming Galaxies
Breanna A. Binder, Ashley K. Anderson, Kristen Garofali +2
We present an analysis of the two-point spatial correlation functions of high-mass X-ray binary (HMXB) and young star cluster (YSC) populations in M31 and M33. We find evidence tha…
A new sample of transient ultraluminous X-ray sources serendipitously discovered by Swift/XRT
Murray Brightman, Jean-Marie Hameury, Jean-Pierre Lasota +11
Ultraluminous X-ray sources (ULXs) are our best laboratories for studying extreme super-Eddington accretion. Most studies of these objects are of relatively persistent sources, how…
The Masses of Supernova Remnant Progenitors in M33
Brad Koplitz, Jared Johnson, Benjamin F. Williams +7
Using resolved optical stellar photometry from the Panchromatic Hubble Andromeda Treasury Triangulum Extended Region (PHATTER) survey, we measured the star formation history (SFH)…
