X-ray binaries radiate brightly from radio to X-ray due to the accretion and ejection of matter in the system. Complex, correlated flux variations probe links between emitting components, on short as well as long timescales. Here I review the progression of multi-wavelength studies of X-ray binaries, focusing on long-term (day+ timescales) correlated behaviour between radio, optical/infrared...

During the hard and quiescent spectral states in X-ray binaries, a non-linear correlation is observed between radio and X-ray luminosities, providing a valuable tool to probe the connection between accretion and jet production. This relation was originally thought to define a single ‘standard’ correlation spanning several orders of magnitude in X-ray luminosity, and was extended to active...
