The dynamics of Galactic centre pulsars: constraining pulsar distances and intrinsic spin-down

Through high-precision radio timing observations, we show that five recycled pulsars in the direction of the Galactic Centre (GC) have anomalous spin period time derivative (\dot P) measurements -- PSRs J1748-3009, J1753-2819, J1757-2745, and J1804-2858 show negative values of \dot P and PSR J1801-3210 is found to have an exceptionally...
