Semidynamical models of radio jets: relativistic beaming and source counts.

摘要: VLBI observations of compact radio sources exhibit core-jet structure and apparent superluminal expansion. Both features can be produced by a relativistic jet radio-emitting plasma beamed toward the observer. This model implies that there should several fainter unbeamed for every source. Partial luminosity functions (the probability distribution observed flux from source at given distance viewed different directions) are calculated models. Kinematical models approximate shock fronts emphasized. These differ kinematically simpler which usually invoked, in velocity emitting fluid, is responsible Doppler boosting, distinct pattern, motion. Numerical calculations emission semidynamical demonstrate wide range partial produced. It concluded counts cannot used as precise probes beaming limited use testing hypothesis. 27 references.
