Very long baseline interferometry detection of an Infrared-Faint Radio Source
Abstract
Infrared-Faint Radio Sources represent a new and unexpected class of object which is bright at radio wavelengths but unusually faint at infrared wavelengths. If, like most mJy radio sources, they were either conventional active or star-forming galaxies in the local Universe, we would expect them to be detectable at infrared wavelengths, and so their non-detection by the Spitzer Space Telescope is surprising. Here, we report the detection of one of these sources using very long baseline interferometry, from which we conclude that the sources are driven by active galactic nuclei. We suggest that these sources are either normal radio-loud quasars at high redshift or abnormally obscured radio galaxies.

We thank the Australian LBA team whose continuing efforts make observations like this possible, and especially the University of Tasmania for making the Hobart antenna available. Like countless other papers, this one has made extensive use of Ned Wright's Cosmology Calculator (http://www.astro.ucla.edu/wright/CosmoCalc.html) and we thank and applaud Ned Wright for making such a valuable tool available to the community. The Australia Telescope is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO. This research has made use of the NASA/IPAC Extragalactic Data base (NED) which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.
