We explore the potential of Pulsar Timing Arrays (PTAs) such as NANOGrav, EPTA, and PPTA to detect the Stochastic Gravitational Wave Background (SGWB) in theories of massive gravity. In General Relativity, the function describing the dependence of the correlation between the arrival times of signals from two pulsars on the angle between them is known as the Hellings-Downs curve. We compute the analogous overlap reduction function for massive gravity, including the additional polarization states… Expand

Including millisecond pulsars inside the core of globular clusters in pulsar timing arrays
We suggest the possibility of including millisecond pulsars inside the core of globular clusters in pulsar timing array experiments. Since they are very close to each other, their gravitational waveExpand


Pulsar Timing Arrays and Gravity Tests in the Radiative Regime
In this paper, we focus on testing gravity theories in the radiative regime using pulsar timing array observations. After reviewing current techniques to measure the dispersion and alternativeExpand
Pulsar-timing arrays, astrometry, and gravitational waves
We discuss the theory of pulsar-timing and astrometry probes of a stochastic gravitational-wave background with a recently developed "total-angular-momentum" (TAM) formalism for cosmologicalExpand
At the limit of weak static fields, general relativity becomes Newtonian gravity with a potential field that falls off as inverse distance rather than a theory of Yukawa-type fields with a finiteExpand
The astrophysics of nanohertz gravitational waves
Pulsar timing array (PTA) collaborations in North America, Australia, and Europe, have been exploiting the exquisite timing precision of millisecond pulsars over decades of observations to search forExpand
Mapping gravitational-wave backgrounds of arbitrary polarisation using pulsar timing arrays
We extend our previous work on applying CMB techniques to the mapping of gravitational-wave backgrounds to backgrounds which have non-GR polarisations. Our analysis and results are presented in theExpand
Pulsar Timing as a Probe of Non-Einsteinian Polarizations of Gravitational Waves
Einstein's theory of gravity predicts waves of the distortion of spacetime with two degrees of polarization; alternative theories predict more polarizations, up to a maximum of six. Although laserExpand
Relic gravitational waves and cosmology
The paper begins with a brief recollection of interactions of the author with Ya B Zeldovich in the context of the study of relic gravitational waves. The principles and early results on theExpand
Measuring stochastic gravitational-wave energy beyond general relativity
Gravity theories beyond general relativity (GR) can change the properties of gravitational waves: their polarizations, dispersion, speed, and, importantly, energy content are all heavily theory-Expand
Graviton Mass Bounds
Recently, aLIGO announced the first direct detections of gravitational waves, a direct manifestation of the propagating degrees of freedom of gravity. The detected signals GW150914 and GW151226 haveExpand
Polarization distortions of lensed gravitational waves
In general relativity (GR), gravitational waves (GWs) propagate the well-known plus and cross tensorial polarization modes which are the signature of a massless spin-2 field. However, diffraction ofExpand
