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 …

We report multiple lines of evidence for a stochastic signal that is correlated among 67
pulsars from the 15 yr pulsar timing data set collected by the North American Nanohertz …

The 15 yr pulsar timing data set collected by the North American Nanohertz Observatory for
Gravitational Waves (NANOGrav) shows positive evidence for the presence of a low …

We present the results of the search for an isotropic stochastic gravitational wave
background (GWB) at nanohertz frequencies using the second data release of the European …

The NANOGrav 15 yr data set shows evidence for the presence of a low-frequency
gravitational-wave background (GWB). While many physical processes can source such low …

Pulsar timing arrays offer a probe of the low-frequency gravitational wave spectrum (1–100
nHz), which is intimately connected to a number of markers that can uniquely trace the …

Various pulsar timing array (PTA) experiments (NANOGrav, EPTA, PPTA, CPTA, including
data from InPTA) very recently reported evidence for excess red common-spectrum signals …

We present results from the search for a stochastic gravitational-wave background (GWB) as
predicted by the theory of General Relativity using six radio millisecond pulsars from the …

Pulsar timing arrays (PTAs) are galactic-scale gravitational wave (GW) detectors. Each
individual arm, composed of a millisecond pulsar, a radio telescope, and a kiloparsecs-long …
