Looking for prematurely `dying', young, compact radio sources
  We present VLBA 1.6, 5, 8.4 and 15 GHz observations of a new sample of weak, young, compact candidates for radio faders selected from the VLA FIRST survey. We claim that some, or even the majority of young sources, may be short-lived phenomena due to a lack of stable fuelling from the black hole and fade before evolving to large extended objects.
