 FIRST ANNOUNCEMENT of the conference: COSPAR-2024-E1.9: Spectral/Timing Properties of AGN: Theory and Observations

Dates: A 3-days long event that will take place during the COSPAR 2024 Assembly in Busan, S. Korea (13-21 July, 2024)

Website: https://www.cospar-assembly.org/admin/session_cospar.php?session=1244

Scientific Rationale: AGN are the most luminous, persistent sources in the Universe. They are also among the most variable at all wavebands. Flux and spectral variations are observed on short time scales and hold significant information regarding the physical processes that operate in the immediate vicinity of their central supper-massive black holes. Significant progress has been made in the last few years, both with observations from the current X-ray observatories (like XMM-Newton, NuSTAR, NICER, Swift and AstroSat) and in theoretical advancements in the study of the corona properties and the inner accretion flow. The main aim of this event is to bring together both theorists and observers, and to review the latest advances in this field, including: i) X-ray spectral/timing properties of AGN, ii) X-ray corona properties and modelling, iv) the disc/corona interplay, v) X-ray reflection and disc thermal reverberation, vi) the nature of the 'soft excess', vii) X-ray polarimetric observations of AGN, and viii) the nature of the inner accretion flow in AGN.
