Kinematic Anisotropies in PTA Observations: Analytical Toolkit

Maximilian Blümke, Kai Schmitz, Tobias Schröder +2

The reported evidence for an isotropic gravitational-wave background (GWB) from pulsar timing array (PTA) collaborations has motivated searches for extrinsic and intrinsic anisotro…

Gravitational waves from cosmic strings for pedestrians

Kai Schmitz, Tobias Schroeder

Cosmic strings represent an attractive source of gravitational waves (GWs) from the early Universe. However, numerical computation of the GW signal from cosmic strings requires the…

Gravitational waves from low-scale cosmic strings without scaling

Kai Schmitz, Tobias Schröder

Cosmic strings are predicted in many extensions of the Standard Model and constitute a plausible source of gravitational waves (GWs) from the early Universe. In a previous article…

On the overlap reduction function of pulsar timing array searches for gravitational waves in modified gravity

Nina Cordes, Andrea Mitridate, Kai Schmitz +2

Pulsar Timing Array (PTA) searches for gravitational waves (GWs) aim to detect a characteristic correlation pattern in the timing residuals of galactic millisecond pulsars. This pa…

The NANOGrav 15 yr Data Set: Running of the Spectral Index

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +102

The NANOGrav 15-year data provides compelling evidence for a stochastic gravitational-wave (GW) background at nanohertz frequencies. The simplest model-independent approach to char…

Gravitational waves from low-scale cosmic strings

Kai Schmitz, Tobias Schröder

Cosmic strings are a common prediction in many grand unified theories and a promising source of stochastic gravitational waves (GWs) from the early Universe. In this paper, we poin…
