I analyzed the neutrinos emitted by a binary neutron star merger remnant and compared the neutrino distribution function of the MC scheme to a two-moment scheme. We used a Monte-Carlo (MC) algorithm to analytically solve Boltzmann's equations of radiation transport. Signal Private Messenger is a free messaging service that puts security and privacy first, delivering a polished and safe group, voice, and video chat. I will also be covering the work I have done in regarding neutrino transport schemes. This method is not limited to binary neutron star mergers and can be applied to any generic merger system. With data from the simulation, I used classical mechanics (accounting for relativistic corrections) to recreate the time evolution of particle trajectories in order to model the matter density distribution at any arbitrary time. The merger system consists of a 1.2M and 1.4M neutron star which are counter-rotating with respect to one another. In this study I have performed a simulation of a binary neutron star merger using the SpEC-Hydro code. Therefore, simulations that accurately model the time evolution of matter outflows are needed to study neutron star mergers. What we detect on Earth are kilonova emissions powered by the radioactive decays of these heavy, unstable elements. Matter is ejected in the merging process and forms the outflow which provides a neutron-rich environment for rapid neutron capture (r-process) to occur leading to the nucleosynthesis of heavy elements. Studies of neutron star mergers are significant because the multi-messenger signals in the form of gravitational waves and electromagnetic waves can inform us on the nuclear physics of neutron stars and the creation of heavy elements in the universe. The MESSENGER is devoted to all aspects of messenger- signaling, from the upstream activation of the receptors of the first messengers to the downstream. This presented for the first time, gravitational waves originating from a neutron star - neutron star merger. In 2017, LIGO detected gravitational waves from GW170817.
