Low-frequency View of GW170817/GRB 170817A with the Giant Metrewave Radio Telescope

We thank the staff of the GMRT that made these observations possible. GMRT is run by the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research. We thank Avishay Gal-Yam and Doron Kushnir for using the high-performance computing (HPC) facility WEXAC at the Weizmann Institute of Science. The Weizmann HPC facility is partly supported by the Israel Atomic Energy Commission—The Council for Higher Education—Pazi Foundation and partly by a research grant from The Abramson Family Center for Young Scientists. Development of the BOXFIT code was supported in part by NASA through grant NNX10AF62G issued through the Astrophysics Theory Program and by the NSF through grant AST-1009863. Simulations for BOXFIT version 2 have been carried out in part on the computing facilities of the Computational Center for Particle and Astrophysics (C2PAP) of the research cooperation "Excellence Cluster universe" in Garching, Germany. This work made use of the IAA-CSIC high-performance (HPC) and throughput (HTC) computing infrastructure.
