We report 21-yr timing of one of the most precise pulsars: PSR J1713+0747. Its pulse times of arrival are well modeled by a comprehensive pulsar binary model including its three-dimensional orbit and a noise model that incorporates correlated noise such as jitter and red noise. Its timing residuals have weighted root mean square $\sim 92$ ns. The new dataset allows us to update and improve previous measurements of the system properties, including the masses of the neutron star ($1.31\pm0.11…

We analyze 24 binary radio pulsars in the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) nine-year data set. We make fourteen significant measurements of Shapiro delay,
An independent test on the local position invariance of gravity with the triple pulsar PSR J0337+1715
We design a direct test of the local position invariance (LPI) in the post-Newtonian gravity, using the timing observation of the triple pulsar, PSR J0337+1715. The test takes advantage of the large
Very Long Baseline Astrometry of PSR J1012+5307 and its Implications on Alternative Theories of Gravity
PSR J1012+5307, a millisecond pulsar in orbit with a helium white dwarf (WD), has been timed with high precision for about 25 years. One of the main objectives of this long-term timing is to use the

Testing the Universality of Free Fall towards Dark Matter with Radio Pulsars.
A novel celestial experiment using the orbital dynamics from radio timing of binary pulsars, and a competing limit on η_{DM} from a neutron-star-white-dwarf (NS-WD) system is obtained, which probes the hypothesis that gravity is the only long-range interaction between DM and ordinary matter.
