  Very-long-baseline interferometry can image the parsec-scale structure of
radio jets, but the accretion disk close to the black hole remains invisible.
One way to probe this accretion flow is provided by X-ray flux density
monitoring and spectroscopy. Here we report on preliminary results of a
multi-band campaign on NGC1052 with the goal of combining both approaches to
access to the innermost regions of this active galaxy and to establish a
connection between the relativistic jets and the accretion region.
