We present 230 GHz continuum fluxes of blazars on the Fermi LAT Monitored Source List and of several blazars added after the Fermi LAT team reported flaring activity. Our science goal is to determine how and where relativistic charged particles emit synchrotron radiation and also act as scatterers of low energy photons (from jets, dust, the Broad Line Region and the hot corona) up to gamma ray energies.
The data were obtained at approximately two-three week intervals at the Submillimeter Array, beginning in February 2009 and ending in November 2010. This program provides more evenly and frequently sampled data than the Submillimeter Array's ongoing flux density monitoring of quasars that are typically bright in the mm/submm bands, in order to optimally choose quasars for use as interferometric calibration sources (led by M. Gurwell (CfA); see http://sma1.sma.hawaii.edu/callist/callist.html/ ). The resulting light curves may be correlated with Fermi LAT photometry, Swift and RXTE observations, and related ground based monitoring programs. From the comparison, time delays between high and low levels at different bands can be derived. We can also compare the relative amplitudes at millimeter and gamma ray bands of flaring and quiescent levels.
