GCN Circular 29053
K. D. Alexander, A. Hajela, R. Margutti, J. Bright (Northwestern U.), T. Eftekhari (Harvard U.), A. Kathirgamaraju (UC Berkeley), and E. Berger (Harvard U.) report on behalf of a larger collaboration: We observed GW170817 with the NSF���s Karl G. Jansky Very Large Array (the VLA) at t =1216 days (~3.3 years) after the binary neutron star merger (joint program SL0449, PI: Margutti). In our preliminary analysis, no radio emission is detected at the location of GW170817; we infer a 3-sigma upper limit of ~13 microJy at a central frequency of 3 GHz. Assuming the X-ray flux density recently reported by Hajela et al. (GCN 29041) and a simple power-law spectrum, this is fully consistent with the F_nu ~ nu^-0.575 spectrum observed throughout GW170817���s earlier evolution (e.g. Hajela et al. 2019). We thank the VLA staff for scheduling and executing these observations.
