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…

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

TLDR
The MESSENGER data collected over 7 years are used to estimate parameters related to general relativity and the evolution of the Sun to confirm the validity of the strong equivalence principle and confirm the Nordtvedt parameter.

Testing the Universality of Free Fall towards Dark Matter with Radio Pulsars.
TLDR
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.
Studying the Solar system with the International Pulsar Timing Array
Pulsar-timing analyses are sensitive to errors in the Solar-system ephemerides (SSEs) that timing models utilize to estimate the location of the Solar-system barycentre, the quasi-inertial reference
