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…
Chasing obscuration in type-I AGN: discovery of an eclipsing clumpy wind at the outer broad-line region of NGC 3783
M. Mehdipour, J. S. Kaastra, G. A. Kriss +21
In 2016 we carried out a Swift monitoring program to track the X-ray hardness variability of eight type-I AGN over a year. The purpose of this monitoring was to find intense obscur…
X-ray bolometric corrections for Compton-thick active galactic nuclei
M. Brightman, M. Baloković, D. R. Ballantyne +16
We present X-ray bolometric correction factors, (), for Compton-thick (CT) active galactic nuclei (AGN) with the aim of testing AGN torus models, prob…
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…
X-ray Lags in PDS 456 Revealed by Suzaku Observations
Chia-Ying Chiang, E. M. Cackett, A. Zoghbi +5
X-ray reverberation lags from the vicinity of supermassive black holes have been detected in almost 30 AGN. The soft lag, which is the time delay between the hard and soft X-ray li…
