NICER observation list: Target ID 353604

We propose monitoring campaigns for five pulsars (PSR J0537-6910, J1101-6101, J1412+7922, J1849-0001, and J2229+6114), four of which can only be done via X-ray observations using NICER. These data will allow us to compute accurate phase-connected timing models for each pulsar, which will enable LIGO/Virgo to perform sensitive searches for gravitational waves from these young and potentially strong gravitational-wave sources. In order for our proposed observations to occur contemporaneously with LIGO/Virgo's observing runs, which take place from 2019 to mid-2020 and restarts in 2021, we request multi-year observations. Our high cadence observations of J0537-6910 will also provide an opportunity to further pin-down this pulsar's unique glitch predictability and to measure glitch signatures.
