Is there a UV/X-ray connection in IRAS 13224-3809?
D. J. K. Buisson, A. M. Lohfink, W. N. Alston +16
We present results from the optical, ultraviolet and X-ray monitoring of the NLS1 galaxy IRAS 13224-3809 taken with Swift and XMM-Newton during 2016. IRAS 13224-3809 is the most va…
NuSTAR view of the black hole wind in the galaxy merger IRAS F111193257
F. Tombesi, S. Veilleux, M. Melendez +5
Galactic winds driven by active galactic nuclei (AGN) have been invoked to play a fundamental role in the co-evolution between supermassive black holes and their host galaxies. Fin…
Paving the way to simultaneous multi-wavelength astronomy
M. J. Middleton, P. Casella, P. Gandhi +49
Whilst astronomy as a science is historically founded on observations at optical wavelengths, studying the Universe in other bands has yielded remarkable discoveries, from pulsars…
Ultrafast outflows disappear in high radiation fields
Ciro Pinto, William Alston, Michael L. Parker +8
Ultrafast outflows (UFOs) are the most extreme winds launched by active galactic nuclei (AGN) due to their mildly-relativistic speeds (~0.1-0.3c) and are thought to significantly c…
Disentangling the Complex Broadband X-ray Spectrum of IRAS 13197-1627 with NuSTAR, XMM-Newton and Suzaku
D. J. Walton, M. Brightman, G. Risaliti +8
We present results from a coordinated -+ observation of the type 1.8 Seyfert galaxy IRAS 13197-1627. This is a highly complex source, with strong contributions…
Revealing the ultra-fast outflow in IRAS 13224-3809 through spectral variability
Michael L. Parker, William N. Alston, Douglas J. K. Buisson +6
We present an analysis of the long-term X-ray variability of the extreme narrow-line Seyfert 1 (NLS1) galaxy IRAS 13224-3809 using principal component analysis (PCA) and fractional…
The X-ray reflection spectrum of the radio-loud quasar 4C 74.26
Anne Lohfink, Andrew Fabian, David Ballantyne +11
The relativistic jets created by some active galactic nuclei are important agents of AGN feedback. In spite of this, our understanding of what produces these jets is still incomple…
The high-Eddington NLS1 Ark 564 has the coolest corona
E. Kara, J. A. Garcia, A. Lohfink +4
Ark 564 is an archetypal Narrow line Seyfert 1 that has been well observed in soft X-rays from 0.3-10 keV, revealing a steep spectrum, strong soft excess, iron K emission line and…
The response of relativistic outflowing gas to the inner accretion disk of a black hole
Michael L. Parker, Ciro Pinto, Andrew C. Fabian +21
Active galactic nucleus (AGN) feedback is the process by which supermassive black holes in the centres of galaxies may moderate the growth of their hosts. Gas outflows from superma…
Properties of AGN coronae in the NuSTAR era II: hybrid plasma
A. C. Fabian, A. Lohfink, R. Belmont +2
The corona, a hot cloud of electrons close to the centre of the accretion disc, produces the hard X-ray power-law continuum commonly seen in luminous Active Galactic Nuclei (AGN).…
A Long Look At MCG-5-23-16 With NuSTAR: I- Relativistic Reflection And Coronal Properties
Abderahmen Zoghbi, G. Matt, J. M. Miller +13
MCG-5-23-16 was targeted in early 2015 with a half mega-seconds observing campaign using NuSTAR. Here we present the spectral analysis of these datasets along with an earlier obser…
