Ultraluminous X-ray sources in the first eROSITA survey I. Candidate catalogs
P. Weber, T. P. Roberts, S. Hämmerich +28
Ultraluminous X-ray sources (ULXs) are luminous non-nuclear X-ray point sources embedded in galaxies. Their luminosities exceeding 10^39 erg/s potentially require sub-Eddington acc…
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…
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…
X-ray Properties of NGC 253's Starburst-Driven Outflow
Sebastian Lopez, Laura A. Lopez, Dustin D. Nguyen +5
We analyze image and spectral data from 365~ks of observations from the {\it Chandra} X-ray Observatory of the nearby, edge-on starburst galaxy NGC 253 to constrain proper…
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…
On the X-ray Spectral Energy Distributions of Star-Forming Galaxies: the 0.3-30 keV Spectrum of the Low-Metallicity Starburst Galaxy VV 114
Kristen Garofali, Bret D. Lehmer, Antara Basu-Zych +6
Binary population synthesis combined with cosmological models suggest that X-ray emission from star-forming galaxies, consisting primarily of emission from X-ray binaries (XRBs) an…
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…
Astro 2020 Science White Paper: Time Domain Studies of Neutron Star and Black Hole Populations: X-ray Identification of Compact Object Types
N. Vulic, A. E. Hornschemeier, V. Antoniou +16
What are the most important conditions and processes governing the growth of stellar-origin compact objects? The identification of compact object type as either black hole (BH) or…
On the Nature of the X-ray Emission from the Ultraluminous X-ray Source, M33 X-8: New Constraints from NuSTAR and XMM-Newton
Lacey A. West, Bret D. Lehmer, Daniel Wik +12
We present nearly simultaneous NuSTAR and XMM-Newton observations of the nearby (832 kpc) ultraluminous X-ray source (ULX) M33 X-8. M33 X-8 has a 0.3-10 keV luminosity of LX ~ 1.4…
