Description
Aqueye+ and Iqueye are two astronomical instruments designed to exploit the highest time resolution
achievable using modern electronics and detectors in the optical band. They are used
to explore the quantum properties of light (e.g., through intensity interferometry measurements)
and to enable the study of rapid optical variability down to the sub-millisecond level. This extreme
timing capability is crucial for characterising certain important classes of astrophysical sources,
in particular (millisecond) pulsars and X-ray binaries. Along with SiFAP2, Aqueye+ and Iqueye
are among the most powerful optical timing facilities currently in operation. In this presentation,
I will highlight some of the most recent results that we have obtained, emphasising the multiinstrument
and multi-wavelength synergies. I will also present future instrumental developments
of this project and the scientific prospects for the coming years, including the possibility of offering
Iqueye at Gemini South.
