NICER observation list: Target ID 750805

Abstract

We propose monitoring observations of four radio-quiet X-ray-only pulsars (and PSR B0540-69), each of which can only be done using NICER, with total Cycle 6 exposure times of 208 ks for PSR J0058-7218, 26 ks for PSR B0540-69, 84 ks for PSR J1412+7922, 90 ks for PSR J1811-1925, and 50 ks for PSR J1849-0001. These data allow computation of an accurate rotation phase-connected timing model for each pulsar, which enable the most sensitive gravitational wave searches of LIGO/Virgo/KAGRA data from these young, fast-spinning, and potentially strong gravitational-wave emitting pulsars. We request multi-cycle observations to ensure NICER data overlaps contemporaneously with the current gravitational wave observing run that goes through early 2025.
