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…
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…
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…
A long hard-X-ray look at the dual active galactic nuclei of M51 with NuSTAR
M. Brightman, M. Baloković, M. Koss +14
We present a broadband X-ray spectral analysis of the M51 system, including the dual active galactic nuclei (AGN) and several off-nuclear point sources. Using a deep observation by…
Long-term optical variability of high-mass X-ray binaries. II. Spectroscopy
P. Reig, A. Nersesian, A. Zezas +2
We present the results of our monitoring program to study the long-term variability of the Halpha line in high-mass X-ray binaries. We have carried out the most complete optical sp…
Disc-loss episode in the Be shell optical counterpart to the high-mass X-ray binary IGR J21343+4738
P. Reig, A. Zezas
The main goal of this work is to determine the properties of the optical counterpart to the INTEGRAL source IGR J21343+4738, and study its long-term optical variability. We present…
