Probing the Strong Gravity Region of Black Holes with eXTP

Qingcui Bu, Cosimo Bambi, Lijun Gou +42

We present the novel capabilities of the enhanced X-ray Timing and Polarimetry (eXTP) mission to study the strong gravity region around stellar-mass black holes in X-ray binary sys…

Sub-second optical/near-infrared quasi-periodic oscillations from the black hole X-ray transient Swift J1727.8-1613

F. M. Vincentelli, T. Shahbaz, P. Casella +14

We report on the detection of optical/near-infrared (O-IR) quasi-periodic oscillations (QPOs) from the black hole X-ray transient Swift J1727.8-1613. We obtained three X-ray and O-…

Modelling variability power spectra of active galaxies from irregular time series

Mehdy Lefkir, Simon Vaughan, Daniela Huppenkothen +2

A common feature of Active Galactic Nuclei (AGN) is their random variations in brightness across the whole emission spectrum, from radio to -rays. Studying the nature and origin…

Physical constraints from near-infrared fast photometry of the black-hole transient GX 339-4

F. M. Vincentelli, P. Casella, P. Petrucci +9

We present results from the first multi-epoch X-ray/IR fast-photometry campaign on the black-hole transient GX 339--4, during its 2015 outburst decay. We studied the evolution of t…
