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 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 …

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 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 …

Evidence for a low-frequency stochastic gravitational-wave background has recently been
reported based on analyses of pulsar timing array data. The most likely source of such a …

ABSTRACT The International Pulsar Timing Array 2nd data release is the combination of
data sets from worldwide collaborations. In this study, we search for continuous waves …

We present high-precision timing data over time spans of up to 11 years for 45 millisecond
pulsars observed as part of the North American Nanohertz Observatory for Gravitational …

In this paper, we describe the International Pulsar Timing Array second data release, which
includes recent pulsar timing data obtained by three regional consortia: the European Pulsar …

A bstract Gravitational waves (GWs) from strong first-order phase transitions (SFOPTs) in the
early Universe are a prime target for upcoming GW experiments. In this paper, I construct …
