Living on a Flare: Relativistic Reflection in V404 Cyg Observed by NuSTAR During its Summer 2015 Outburst
D. J. Walton, K. Mooley, A. L. King +19
We present first results from a series of observations of the black hole X-ray binary V404 Cyg obtained during its summer 2015 outburst, primarily focusing on observations…
A 78 Day X-ray Period Detected from NGC 5907 ULX1 by Swift
D. J. Walton, F. Fuerst, M. Bachetti +12
We report the detection of a day period in the X-ray lightcurve of the extreme ultraluminous X-ray source NGC 5907 ULX1 ( erg s$^{-1…
An Iron K Component to the Ultrafast Outflow in NGC 1313 X-1
D. J. Walton, M. J. Middleton, C. Pinto +8
We present the detection of an absorpton feature at keV in the combined X-ray spectrum of the ultraluminous X-ray source NGC 1313 X-1 observed with XMM-New…
False periodicities in quasar time-domain surveys
S. Vaughan, P. Uttley, A. G. Markowitz +5
There have recently been several reports of apparently periodic variations in the light curves of quasars, e.g. PG 1302-102 by Graham et al. (2015a). Any quasar showing periodic os…
The ultraluminous X-ray source NGC 5643 ULX1: a large stellar mass black hole accreting at super-Eddington rates?
F. Pintore, L. Zampieri, A. D. Sutton +3
A sub-set of the brightest ultraluminous X-ray sources (ULXs), with X-ray luminosities well above erg s, typically have energy spectra which can be well described…
The optical-UV emissivity of quasars: dependence on black hole mass and radio loudness
Francesco Shankar, Giorgio Calderone, Christian Knigge +15
We analyzed a large sample of radio-loud and radio-quiet quasar spectra at redshift 1.0 < z < 1.2 to compare the inferred underlying quasar continuum slopes (after removal of the h…
