Has NANOGrav found first evidence for cosmic strings? / Blasi, Simone (Heidelberg, Max Planck Inst.) ; Brdar, Vedran (Heidelberg, Max Planck Inst.) ; Schmitz, Kai (CERN)
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) has recently reported strong evidence for a stochastic common-spectrum process affecting the pulsar timing residuals in its 12.5-year data set. We demonstrate that this process admits an interpretation in terms of a stochastic gravitational-wave background emitted by a cosmic-string network in the early Universe. [...]

Stochastic gravitational-wave background from metastable cosmic strings / Buchmuller, Wilfried (DESY) ; Domcke, Valerie (CERN ; Ecole Polytechnique, Lausanne) ; Schmitz, Kai (CERN)
A metastable cosmic-string network is a generic consequence of many grand unified theories (GUTs) when combined with cosmic inflation. Metastable cosmic strings are not topologically stable, but decay on cosmic time scales due to pair production of GUT monopoles. [...]

Gravitational Waves from Current-Carrying Cosmic Strings / Auclair, Pierre (Louvain U.) ; Blasi, Simone (Brussels U., IIHE) ; Brdar, Vedran (Fermilab ; Northwestern U.) ; Schmitz, Kai (Munster U. ; CERN)
Cosmic strings are predicted by many Standard Model extensions involving the cosmological breaking of a symmetry with nontrivial first homotopy group and represent a potential source of primordial gravitational waves (GWs). Present efforts to model the GW signal from cosmic strings are often based on minimal models, such as, eg, the Nambu--Goto action that describes cosmic strings as exactly one-dimensional objects without any internal structure.
