XMM-Newton Observations of the Narrow-Line Seyfert 1 Galaxy IRAS 132243809 : X-ray Spectral Analysis II
Jiachen Jiang, Thomas Dauser, Andrew C. Fabian +4
Previously, we modelled the X-ray spectra of the narrow-line Seyfert 1 galaxy IRAS 132243809 using a disc reflection model with a fixed electron density of cm.…
Ejection-accretion connection in NLS1 AGN 1H 1934-063
Yerong Xu, Ciro Pinto, Erin Kara +7
Accretion and ejection of matter in active galactic nuclei (AGN) are tightly connected phenomena and represent fundamental mechanisms regulating the growth of the central supermass…
High-density disc reflection spectroscopy of low-mass active galactic nuclei
L. Mallick, A. C. Fabian, J. A. García +13
The standard alpha-disc model predicts an anti-correlation between the density of the inner accretion disc and the black hole mass times square of the accretion rate, as seen in hi…
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…
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…
