Multi-wavelength variability from X-ray binary jets.
Abstract
Jets are associated with accretion processes across all physical scales, from protostars to the super-massive black holes in active galactic nuclei. Nevertheless, many unanswered fundamental questions in accretion physics involve the key role played by the jet, as the launching mechanism, the jet power, and even the jet geometry are unknown in most cases. X-ray binaries are unique laboratories to study astrophysical jets, as they evolve relatively rapidly over a large range of accretion rates. The international community is currently very active in building and harnessing large multi-wavelength campaigns, and new models are being developed that take into account the observed phenomenology. Among the many observing techniques used, the study of simultaneous fast multi-wavelength variability has now become a key tool for studying the Physics of accretion and ejection of relativistic jets in X-ray binaries, as it is yielding new and unique insights in the field. In this talk I will review the state of the field, presenting the latest results obtained through fast IR photometry.
