Recent work has demonstrated the potential of gravitationally lensed quasars to extend measurements of black hole spin out to high-redshift with the current generation of X-ray observatories. Here we present an analysis of a large sample of 27 lensed quasars in the redshift range 1.0<z<4.5 observed with Chandra, utilizing over 1.6 Ms of total observing time, focusing on the rest-frame iron K emission from these sources. Although the X-ray signal-to-noise (S/N) currently available does not…

The Effect of Microlensing on the Observed X-Ray Energy Spectra of Gravitationally Lensed Quasars
The Chandra observations of several gravitationally lensed quasars show evidence for flux and spectral variability of the X-ray emission that is uncorrelated between images and is thought to result
X-Ray Line Profile Variations during Quasar Microlensing
Observations of several gravitationally microlensed quasars in X-rays revealed variations in the profile of the iron Kα line in the course of microlensing events. We explore the effect by simulating
Revisiting the extremely fast disc wind in a gravitationally lensed quasar APM 08279+5255
The gravitationally lensed quasar APM 08279+5255 has the fastest claimed wind from any active galactic nucleus, with velocities of 0.6–0.7c, requiring magnetic acceleration as special relativistic
A selection effect boosting the contribution from rapidly spinning black holes to the cosmic X-ray background
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 (30 keV). In this

THESEUS is an ESA space based project, which aims to explore the early universe by unveiling a complete census of Gamma-ray Burst (GRB) population in the first billion years. This goal is expected to
The physical properties and cosmic environments of quasars in the first Gyr of the universe
Luminous quasars at redshift z &6, i.e. .1 Gyr after the Big Bang, are formidable probes of the early universe, at the edge of the Epoch of Reionization. These sources are predicted to be found in
A full characterization of the supermassive black hole in IRAS 09149–6206
We present new broadband X-ray observations of the type-I Seyfert galaxy IRAS 09149-6206, taken in 2018 with $XMM$-$Newton$, $NuSTAR$ and $Swift$. The source is highly complex, showing a classic
Disentangling the complex broad-band X-ray spectrum of IRAS 13197-1627 with NuSTAR, XMM-Newton and Suzaku
We present results from a coordinated XMM–Newton+NuSTAR observation of the type 1.8 Seyfert galaxy IRAS 13197−1627. This is a highly complex source, with strong contributions from relativistic
XMM-Newton reveals a Seyfert-like X-ray spectrum in the z=3.6 QSO B1422+231
Matter flows in the central regions of quasars during their active phases are probably responsible for the properties of the super-massive black holes and that of the bulges of host galaxies. To
Measuring the Innermost Stable Circular Orbits of Supermassive Black Holes
We present a promising new technique, the g-distribution method, for measuring the inclination angle (i), the innermost stable circular orbit (ISCO), and the spin of a supermassive black hole. The


Reflection from the strong gravity regime in a lensed quasar at redshift z = 0.658
The high spin found here is indicative of growth by coherent accretion for this black hole, and suggests that black-hole growth at 0.5 ≤ z  1 occurs principally by coherent rather than chaotic accretion episodes.
