Abstract:The detection of quasi-periodic oscillations (QPOs) in the emission of active galactic nuclei (AGNs) can provide insights into the physics of the super-massive black-holes (SMBHs) powering these systems, and could represent a signature of the existence of SMBH binaries. The identification of long term QPOs, characterized by periods on the order of several months to years, is particularly challenging and can only be achieved via all-sky monitoring instruments like the Fermi-LAT satellite. We aim to identify QPO… Show more
