Constraints on Short Lived Signals at 150 GHz
Fast radio bursts (FRBs) are bright, millisecond flashes of radio radiation detected at frequencies between 800 MHz and 8 GHz. We present the first rate constraints on millisecond duration celestial transients like FRBs at 150 GHz. Using a year of data from the South Pole Telescope we searched for s...
