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

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. In the second part (if time permits), I will discuss the possibility and prospects of performing GW-triggered stacking searches for high-energy and ultra-high energy neutrinos from BNS mergers in general, at IceCube-Gen2, GRAND, and RNO-G, using the next generation of GW detectors.
