The collection of individually resolvable gravitational wave (GW) events makes up a tiny
fraction of all GW signals that reach our detectors, while most lie below the confusion limit …

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 searched for an isotropic stochastic gravitational wave background in the second data
release of the International Pulsar Timing Array, a global collaboration synthesizing decadal …

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 …

A nanohertz-frequency stochastic gravitational-wave background can potentially be
detected through the precise timing of an array of millisecond pulsars. This background …

Fast radio bursts (FRBs) are millisecond-time-scale bursts of coherent radio emission that
are luminous enough to be detectable at cosmological distances. In this Review, I describe …

Abstract The North American Nanohertz Observatory for Gravitational Waves (NANOGrav)
has reported evidence for the presence of an isotropic nanohertz gravitational-wave …

We present the first 2.5 yr of data from the MeerKAT Pulsar Timing Array (MPTA), part of
MeerTime, a MeerKAT Large Survey Project. The MPTA aims to precisely measure pulse …

Gravitational waves offer a new window to probe the nature of gravity, including answering if
the mediating particle, graviton, has a nonzero mass or not. Pulsar timing arrays measure …

Some compact objects observed in gravitational wave events have masses in the gap
between known neutron stars (NSs) and black holes (BHs). The nature of these mass gap …
