Lense-Thirring precession in ULXs as a possible means to constrain the neutron star equation-of-state

M. J. Middleton, P. C. Fragile, M. Bachetti +11

The presence of neutron stars in at least three ultraluminous X-ray sources is now firmly established and offers an unambiguous view of super-critical accretion. All three systems…

The NuSTAR Serendipitous Survey: Hunting for The Most Extreme Obscured AGN at >10 keV

G. B. Lansbury, D. M. Alexander, J. Aird +27

We identify sources with extremely hard X-ray spectra (i.e., with photon indices of Gamma<0.6 in the 13 sq. deg. NuSTAR serendipitous survey, to search for the most highly obscured…

Disentangling the Complex Broadband X-ray Spectrum of IRAS 13197-1627 with NuSTAR, XMM-Newton and Suzaku

D. J. Walton, M. Brightman, G. Risaliti +8

We present results from a coordinated -+ observation of the type 1.8 Seyfert galaxy IRAS 13197-1627. This is a highly complex source, with strong contributions…

Super-Eddington Accretion onto the Neutron Star NGC 7793 P13: Broadband X-ray Spectroscopy and Ultraluminous X-ray Sources

D. J. Walton, F. Fuerst, F. A. Harrison +8

We present a detailed, broadband X-ray spectral analysis of the ULX pulsar NGC 7793 P13, a known super-Eddington source, utilizing data from the -, and $Chand…
