... with VLBI imaging and spectral-line monitoring have become important tools for probing dense gas near the central engines of these sources, investigating the properties of their accretiondisks and measuring the masses of their (supermassive) black holes ...
... While providing useful clues to determine the nature of the maser in MGJ0414+0534, our singledish data alone are presently insu#cient to confidently exclude either one of the two scenarios, jet vs. accretiondisk. ...

... Our August 1997 and July 1998 coordinated X-ray/infrared campaigns have already yielded important results, including the rst observational evidence linking particle ejection to activity in the inner accretiondisk. ...

... Optical data has shown that the accretiondisk, which was clearly present in 2000 and 2001 in this system, had 'disappeared' nearly 5 months later, and has not reappeared again. ...
