TL;DR
The TANAMI program conducts VLBI monitoring of southern extragalactic gamma-ray sources at multiple frequencies to support multi-wavelength studies and test blazar emission models.
Contribution
It introduces a comprehensive VLBI monitoring program for southern gamma-ray sources and presents initial observational results.
Findings
Monitoring 75 sources with VLBI at 8 and 22 GHz.
Supports joint observations with Fermi and ground-based observatories.
Aids in discriminating between blazar emission models.
Abstract
The TANAMI (Tracking AGN with Austral Milliarcsecond Interferometry) program provides comprehensive VLBI monitoring of extragalactic gamma-ray sources south of declination -30 degrees. Operating at two radio frequencies (8 and 22 GHz), this program is a critical component of the joint quasi-simultaneous observations with the Fermi Gamma-ray Space Telescope and ground based observatories to discriminate between competing theoretical blazar emission models. We describe the TANAMI program and present early results on the 75 sources currently being monitored.
