TANAMI: Parsec Scale AGN Physics in the Multiwavelength Era - Roopesh Ojha Colloquium

ATNF Marsfield Lecture Theatre

Abstract

With its broader energy coverage, higher resolution, wider field of
view and greater sensitivity, the Large Area Telescope (LAT) of the
Fermi Gamma-ray Space Telescope is dramatically increasing our
knowledge of AGN gamma-ray emission. However, discriminating between
competing theoretical models requires quasi-simultaneous observations
across the electromagnetic spectrum.

The TANAMI (Tracking AGN with Austral Milliarcsecond Interferometry)
and associated programs provide comprehensive radio monitoring for
Fermi Gamma-ray Space Telescope sources south of declination -30
degrees. Near simultaneous data from the Swift satellite and ground
based optical facilities span the gap from radio to gamma-ray
energies. We describe the TANAMI program in the context of this
panchromatic suite of observations and present early results.
