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 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…

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…
