Wind-luminosity evolution in NLS1 AGN 1H 0707-495
Yerong Xu, Ciro Pinto, Stefano Bianchi +7
Ultra-fast outflows (UFOs) have been detected in the high-quality X-ray spectra of a number of active galactic nuclei (AGN) with fairly high accretion rates and are thought to sign…
The chameleon on the branches: spectral state transition and dips in NGC 247 ULX-1
A. D'Aì, C. Pinto, M. Del Santo +14
Soft Ultra-Luminous X-ray (ULXs) sources are a subclass of the ULXs that can switch from a supersoft spectral state, where most of the luminosity is emitted below 1 keV, to a soft…
Quasi-periodic dipping in the ultraluminous X-ray source, NGC 247 ULX-1
W. N. Alston, C. Pinto, D. Barret +15
Most ultraluminous X-ray sources (ULXs) are believed to be stellar mass black holes or neutron stars accreting beyond the Eddington limit. Determining the nature of the compact obj…
Long-term pulse period evolution of the ultra-luminous X-ray pulsar NGC 7793 P13
F. Fuerst, D. J. Walton, M. Heida +14
Ultra-luminous X-ray pulsars (ULXPs) provide a unique opportunity to study super-Eddington accretion. We present the results of a monitoring campaign of ULXP NGC 7793 P13. Over our…
XMM-Newton campaign on the ultraluminous X-ray source NGC 247 ULX-1: outflows
C. Pinto, R. Soria, D. Walton +13
Most ULXs are believed to be powered by super-Eddington accreting neutron stars and, perhaps, black holes. Above the Eddington rate the disc is expected to thicken and to launch po…
The Inner Accretion Flow in the Resurgent Seyfert-1.2 AGN Mrk 817
J. M. Miller, Z. Zoghbi, M. T. Reynolds +10
Accretion disks and coronae around massive black holes have been studied extensively, and they are known to be coupled. Over a period of 30 years, however, the X-ray (coronal) flux…
