Rob Fender (Southampton) - Relativistic jets Flexible high time resolution observations of accreting black holes and neutron stars over the past 15 years, as part of mutliwavelength campaigns, have provided arguably the clearest insight into the phenomenology of relativistic accretion, in particular the connection between accretion and relativistic jets. LOFT will continue this work, and will furthermore do so during an era in which we will greatly improve our capability of simultaneous ground-based radio and infrared observations. In this talk I will review the current state of the art, and look forward to what we could do with LOFT in concert with a new generation of ground-based facilities.
