A Newly Identified Transient Ultraluminous X-ray Source in M31
Ferdinand, Murray Brightman, Jean-Marie Hameury +9
Ultraluminous X-ray sources (ULXs) are off-nuclear X-ray sources with luminosities exceeding the Eddington limit of typical stellar-mass compact objects. While most known ULXs are…
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…
A NuSTAR Census of the X-ray Binary Population of the M31 Disk
Hannah Moon, Daniel R. Wik, V. Antoniou +11
Using hard (E>10 keV) X-ray observations with NuSTAR, we are able to differentiate between accretion states, and thus compact object types, of neutron stars and black holes in X-ra…
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…
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…
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)…
X-ray luminosity function of high-mass X-ray binaries: Studying the signatures of different physical processes using detailed binary evolution calculations
Devina Misra, Konstantinos Kovlakas, Tassos Fragos +11
The ever-expanding observational sample of X-ray binaries (XRBs) makes them excellent laboratories for constraining binary evolution theory. Such constraints can be obtained by stu…
Multiwavelength Characterization of the High Mass X-ray Binary Population of M31
Margaret Lazzarini, Benjamin F. Williams, Meredith Durbin +7
We present our analysis of high quality high mass X-ray binary (HMXB) candidates in M31 selected from point-source optical-counterpart candidates from the Chandra-PHAT survey catal…
Neutron Stars and Black Holes in the Small Magellanic Cloud: The SMC NuSTAR Legacy Survey
M. Lazzarini, B. F. Williams, A. E. Hornschemeier +18
We present a source catalog from the first deep hard X-ray ( keV) survey of the Small Magellanic Cloud (SMC), the NuSTAR Legacy Survey of the SMC. We observed three fields, f…
