This material relates to a paper that appeared in the Oct. 16, 2017, online issue of Science, published by AAAS. The paper, by M.M. Kasliwal at California Institute of Technology in Pasadena, CA, and colleagues was titled, 'Illuminating gravitational waves: A concordant picture of photons from a neutron star merger.' view more
