NICER observation list: Target ID 669602

Multimessenger astronomy is a powerful new method for understanding astrophysical processes. This was illustrated in 2017 when IceCube reported a high-energy neutrino found to be coincident with a very-high-energy flaring blazar (detected by Fermi and MAGIC). Since then, various multimessenger studies involving neutrinos and photon data have occurred, but the associations between neutrinos and active galactic nuclei (AGN) remain uncertain. We propose a monitoring program for two AGN, NGC1068 and PKS1502+106, using NICER and NuSTAR to study the X-ray-neutrino connection. This analysis will make use of both model-dependent and model-independent approaches using observed X-ray and IceCube non-public data and will also serve as a trigger for real-time follow-up using IceCube.
