TL;DR
This paper advocates for dedicated long-duration XMM-Newton observations of AGN to advance X-ray reverberation studies, enabling detailed insights into the dynamic corona of black holes.
Contribution
It proposes a dedicated legacy observing program with XMM-Newton for long-term AGN reverberation studies, a novel approach to understanding black hole coronae.
Findings
Enhanced understanding of AGN corona dynamics
Feasibility of long-duration XMM-Newton observations
Potential for groundbreaking reverberation research
Abstract
XMM-Newton is capable of making a transformational advance in our understanding of how luminous accreting black holes work, by dedicating about 10 per cent of future observing time to long observations, of order Megaseconds, to X-ray variable Active Galactic Nuclei (AGN) research. This would enable reverberation studies, already a commonplace feature of AGN, to proceed to the next level and follow the behaviour of the powerful dynamic corona. Such a dedicated legacy programme can only be carried out with XMM-Newton.
