The WISSH quasars project VII. The impact of extreme radiative field in the accretion disk and X-ray corona interplay
L. Zappacosta, E. Piconcelli, M. Giustini +14
Hyperluminous quasars ( erg s) are ideal laboratories to study the interaction and impact of extreme radiative field and the most powerful winds…
Observatory science with eXTP
Jean J. M. in 't Zand, Enrico Bozzo, Jinlu Qu +181
In this White Paper we present the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies related to Observatory Science targets. These include flaring s…
Feedback and feeding in the context of galaxy evolution with SPICA: direct characterization of molecular outflows and inflows
E. González-Alfonso, L. Armus, F. J. Carrera +28
A far-infrared observatory such as the {\it SPace Infrared telescope for Cosmology and Astrophysics} ({\it SPICA}), with its unprecedented spectroscopic sensitivity, would unveil t…
The WISSH Quasars Project III. X-ray properties of hyper-luminous quasars
S. Martocchia, E. Piconcelli, L. Zappacosta +14
We perform a survey of the X-ray properties of 41 objects from the WISE/SDSS selected Hyper-luminous (WISSH) quasars sample, composed by 86 broad-line quasars (QSOs) with bolometri…
Highly ionized disc and transient outflows in the Seyfert galaxy IRAS 18325-5926
K. Iwasawa, A. C. Fabian, E. Kara +3
We report on strong X-ray variability and the Fe K band spectrum of the Seyfert galaxy IRAS 18325-5926 obtained from the 2001 XMM-Newton EPIC pn observation of a 120 ks duration. W…
A Variable-Density Absorption Event in NGC 3227 mapped with Suzaku and Swift
T. Beuchert, A. G. Markowitz, F. Krauß +15
The morphology of the circumnuclear gas accreting onto supermassive black holes in Seyfert galaxies remains a topic of much debate. As the innermost regions of Active Galactic Nucl…
