AzTEC/ASTE Millimeter-wave Monitoring and Target-of-opportunity Observations of Selected Radio-bright Fermi-detected Gamma-ray Blazars and GRBs
Abstract
We report on correlative millimeter-wave radio observations at 1.1 mm of high-priority Fermi-detected gamma-ray blazars using the AzTEC bolometer-array camera mounted on the 10-m ASTE radio telescope in northern Chile. These observations were carried out during the latter part of the 2008 observing season, overlapping with the first months of operation of the Fermi Observatory. High-priority blazars were monitored and we responded as well to Fermi alerts of elevated gamma-ray emission or flaring activity. We also report on the upper limits obtained to millimeter-wave emission in the early afterglow from GRB 081121. These correlative measurements constituted a pilot observing program that will be extended and expanded to include numerous additional gamma-ray targets for the Large Millimeter Telescope as part of its commissioning operations over the coming year. This work is supported in part by the National Science Foundation.
