The 1974 discovery, by Russell A Hulse and Joseph H Taylor, of the first binary pulsar, PSR B1913+16, opened up new possibilities for the study of relativistic gravity. PSR B1913+16, as well as several other binary pulsars, provided direct observational proof that gravity propagates at the velocity of light and has a quadrupolar structure. Binary pulsars also provided accurate tests of the strong-field regime of relativistic gravity. General relativity has passed all of the binary pulsar tests… 
Testing general relativity through the computation of radiative terms and within the neutron star strong-field regime
The recent detection of coalescing black holes by theLaser InterferometerGravitationalwave Observatory has brought forth the era of gravitational wave astronomy. Physicists are only now beginning to

Cosmological observations over past couple of decades favor our universe with a tiny positive cosmological constant. Presence of cosmological constant not only imposes theoretical challenges in
More than the sum of its parts: Combining parametrized tests of extreme gravity
We connect two formalisms that describe deformations away from general relativity, one valid in the strong-field regime of neutrons stars and another valid in the radiative regime of gravitational

Saturation of the f -mode instability in neutron stars. II. Applications and results
We present the first results on the saturation of the f-mode instability in neutron stars, due to nonlinear mode coupling. Emission of gravitational waves drives the f-mode (fundamental mode)

A precise mass measurement of PSR J2045 + 3633
We present the results of a timing analysis undertaken with the goal of obtaining an improved mass measurement of the recycled pulsar J2045+3633. Using regular high-cadence observations with the
Exterior spacetime of relativistic stars in scalar-Gauss-Bonnet gravity
The spacetime around compact objects is an excellent place to study gravity in the strong, nonlinear, dynamical regime where solar system tests cannot account for the effects of large curvature.

At the turn of the 1980s and 1990s, on the eve of the great leap in scale from the resonant bars to the long-baseline interferometers LIGO and Virgo, the four European groups then engaged in the
Asymptotics with a positive cosmological constant. III. The quadrupole formula
Almost a century ago, Einstein used a weak field approximation around Minkowski spacetime to calculate the energy carried away by gravitational waves emitted by a time changing mass-quadrupole.

TOPICAL REVIEW: The double pulsar system: a unique laboratory for gravity
The PSR J0737–3039 is a double neutron star system in which both stars are detectable as active radio pulsars. The pair, consisting of an old, mildly recycled 23-ms pulsar and a young 2.8-s pulsar,
Tests of General Relativity from Timing the Double Pulsar
TLDR
By measuring relativistic corrections to the Keplerian description of the orbital motion, it is found that the “post-Keplerian” parameter s agrees with the value predicted by general relativity within an uncertainty of 0.05%, the most precise test yet obtained.

TLDR
A detailed account of the parametrized post-Keplerian'' (PPK) formalism, a general phenomenological framework designed to extract the maximum possible information from pulsar timing and pulse-structure data, and how it can be combined with the predictions of a rather generic class of tensor biscalar theories to bring together tests based on observations of several different pulsars.
A two-solar-mass neutron star measured using Shapiro delay
TLDR
Radio timing observations of the binary millisecond pulsar J1614-2230 that show a strong Shapiro delay signature are presented and the pulsar mass is calculated to be (1.97 ± 0.04)M⊙, which rules out almost all currently proposed hyperon or boson condensate equations of state.
