Title: Multi-messenger signatures from magnetar remnants of binary neutron star mergers

Abstract: Binary neutron-star (BNS) mergers can be accompanied by multi-messenger emissions, including gravitational wave (GW), neutrino, and electromagnetic (EM) signals. Some fraction of BNS mergers may result in a rapidly spinning long-lived magnetar as a remnant, which can enhance both the EM and neutrino emissions. I will discuss the possible neutrino and EM signatures from such systems and prospects for their detectability.
