Multiwavelength Observing - Support Programs
A number of observing programs have been established to provide either regular monitoring or targeted observations specifically designed to help support the Fermi science effort. Many of the programs listed below provide their datasets publicly as a service to the science community. These data are not part of the Fermi public dataset, so their use should be coordinated directly with the project leads. Please refer to each site for data usage and/or attribution information. For more information on coordinated observations with the LAT, please contact the LAT Multiwavelength Coordinating Group.
Blazar Monitoring
The Radio/Gamma-ray AGN Working Group Home Page provides more information on ongoing science and data acquisition activities in support of Fermi AGN Science.
- Blazar Monitoring List
This page contains all blazars known to be regularly monitored at optical wavelengths, plus all the MOJAVE and Boston University monitored sources and known TeV blazars. (Courtesy of the Mojave group). - Owens Valley Radio Observatory (OVRO) Monitoring of Fermi Blazars
40M Radio telescope (15 GHz) monitoring more than 1200 blazars about twice per week. - MOJAVE/2cm Survey Data Archive
An imaging survey of compact radio sources at 15 GHz. Many sources are from the Fermi-LAT First Point Source Catalog - University of Michigan Radio Astronomy Observatory
Tabulated daily averages for flaring gamma-ray blazars. - TANAMI (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry)
Tracking the jets of flaring Fermi blazars south of -30 degrees declination at 8.4GHz and 22GHz - Boston University Blazar Group
Provides monthly Images of gamma-ray blazars with the VLBA at 43 GHz - SMARTS Optical/IR Observationsof LAT Monitored Blazars
Uses three telescopes at CTIO to monitor all blazars on the LAT Monitored Sources List that are viewable from Chile - Optical Linear Polarization Monitoring of Bright Fermi Blazars
Regular monitoring of gamma-ray bright blazars from University of Arizona's Steward Observatory - Swift-XRT Monitoring of Fermi-LAT Sources of Interest
Near-real time monitoring of sources on the LAT Monitored Sources List from the Swift XRT instrument - VIPS (The VLBA Imaging and Polarimetry Survey)
A combined 5 GHz and 15 GHz survey with the Very Long Baseline Array of ~1100 active galactic nuclei (AGN) with full polarization and high dynamic range
Pulsar Timing Observations
The Fermi LAT Pulsar Timing Consortium (PTC) was formed before launch to organize regular radio and X-ray timing of over 200 pulsars to ensure that accurate and contemporaneous ephemerides are available for folding the LAT gamma-ray data to search for gamma-ray pulsations. This work is described by Smith, et al. (2008), and Weltevrede, et al. (2010). For energetic young pulsars, frequent monitoring is required to maintain phase connection in the presence of strong timing noise and glitches, so this work is of critical importance to the LAT science mission. Ephemerides and radio profiles used in published Fermi results have been made available through the FSSC.
