During my career I touched several lines of research: especially accreting neutron stars and ultra-luminous X-ray sources, but including also FRBs, GWs and even Inter-Galactic Medium…but the Physics of accretion-ejection in stellar-mass black holes remains my main scientific interest.
I study black-holes, and especially their jets, at all wavelengths, from radio to infrared to X-rays, and using as many telescopes as possible. In particular, I pioneered the use of infrared fast photometry to securely identify and study the fast variable emission from jets in X-ray binaries.
