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…
Ionised Emission and Absorption in a Large Sample of Ultraluminous X-ray Sources
P. Kosec, C. Pinto, C. S. Reynolds +6
Most Ultraluminous X-ray sources (ULXs) are thought to be powered by super-Eddington accretion onto stellar-mass compact objects. Accretors in this extreme regime are naturally exp…
The nature of the extreme X-ray variability in the NLS1 1H 0707-495
M. L. Parker, W. N. Alston, L. Härer +11
We examine archival XMM-Newton data on the extremely variable narrow-line Seyfert 1 (NLS1) active galactic nucleus (AGN) 1H 0707-495. We construct fractional excess variance (Fvar)…
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…
Extreme Relativistic Reflection in the Active Galaxy ESO 033-G002
D. J. Walton, M. Balokovic, A. C. Fabian +13
We present the first high signal-to-noise broadband X-ray spectrum of the radio-quiet type-2 Seyfert ESO 033-G002, combining data from - and . The nuclear X-ra…
Broadband X-ray spectral variability of the pulsing ULX NGC 1313 X-2
A. Robba, C. Pinto, D. J. Walton +12
It is thought that ultraluminous X-ray sources (ULXs) are mainly powered by super-Eddington accreting neutron stars or black holes as shown by recent discovery of X-ray pulsations…
