VLBA Studies of the Structure and Evolution of Relativistic Quasar and AGN jets - Dr. Ken Kellerman Colloquium

ATNF Marsfield Lecture Theatre

Abstract

Observations with very long baseline radio interferometers provide a
direct method to study the formation, acceleration, and propagation of
relativistic jets in powerful extragalactic radio sources. I will
describe a ten year VLBA program to study the structure, collimation,
and flow in quasars and other active galactic nuclei and will discsuss
the interpretation in terms of relativistic beaming models, including
the distribution of apparent and intrinsic Lorentz factors, and the
difference between pattern and bulk motions. The observed kinematic
properties will be illustrated by reference to individual sources which
have been studied in some detail.
