Abstract
In this work, the authors show how models of kilonovae, which arise from the mergers of neutron stars and black holes, can be used as standard candles, where their luminosity can be measured by measuring the evolution of their color. They show how detection of kilonovae can probe of the expansion rate of the Universe as the detection of gravitational waves.
