Title: Redshifts and Optical Identifications of TANAMI/Fermi AGN

Abstract: We wish to measure redshifts for the opticalidentifications of those gamma-ray loud southern hemisphere extragalactic radio sources being monitored by the TANAMI program that lack them. We also propose imaging of those sources that currently lack optical identifications after which their redshifts will also be measured. The study of blazar physics has been revolutionized by \sl Fermi which has ushered in the age of quasi-simultaneous multi-wavelength studies for which knowledge of physical quantities like blazar-jet luminosities and speeds are crucial. TANAMI is the only significant source of milliarcsecond scale radio information for the southern third of the sky. Source redshifts are essential to determine the linear sizes and physical properties of TANAMI/Fermi sources. Please Note: This proposal has been approved for Gemini observing time in Cycle 5 of the Fermi Guest Investigator program (NASA Fermi Cycle 5 - #51378 Pursimo)
