Arcminute Microkelvin Imager observations at 15.5 GHz of the tidal disruption event Swift J164449.3+573451 from 2011 Mar to 2014 Mar

Abstract

Radio monitoring of the tidal disruption event Swift J164449.3+573451 at 15.5 GHz with the Arcminute Microkelvin Imager is reported. The results from 308 observations made from 2011 Mar to 2014 Mar are presented. These show a steady rise in flux density from $\approx$3 mJy (three days after the initial $\gamma$-ray detection of Swift J164449.3+573451), to a peak of nearly 30 mJy $\approx$140 days later, followed by a steady decline.
