NuSTAR observations of Mrk 766: distinguishing reflection from absorption
D. J. K. Buisson, M. L. Parker, E. Kara +14
We present two new NuSTAR observations of the narrow line Seyfert 1 (NLS1) galaxy Mrk 766 and give constraints on the two scenarios previously proposed to explain its spectrum and…
SUPERSHARP - Segmented Unfolding Primary for Exoplanet Research via Spectroscopic High Angular Resolution Photography
Ian Parry, Didier Queloz, Grant Kennedy +20
We propose to search for biosignatures in the spectra of reflected light from about 100 Earth-sized planets that are already known to be orbiting in their habitable zones (HZ). For…
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).…
The detection and X-ray view of the changing look AGN HE 1136-2304
M. L. Parker, S. Komossa, W. Kollatschny +9
We report the detection of high-amplitude X-ray flaring of the AGN HE 1136-2304, which is accompanied by a strong increase in the flux of the broad Balmer lines, changing its Seyfe…
A selection effect boosting the contribution from rapidly spinning black holes to the Cosmic X-ray Background
R. V. Vasudevan, A. C. Fabian, C. S. Reynolds +3
The Cosmic X-ray Background (CXB) is the total emission from past accretion activity onto supermassive black holes in active galactic nuclei (AGN) and peaks in the hard X-ray band…
