Extension of the Bayesian searches for anisotropic stochastic gravitational-wave background with nontensorial polarizations

Extension of the Bayesian searches for anisotropic stochastic gravitational-wave background with nontensorial polarizations

The recent announcement of strong evidence for a stochastic gravitational-wave background (SGWB) by various pulsar timing array collaborations has highlighted this signal as a promising candidate for future observations. Despite its nondetection by ground-based detectors such as Advanced LIGO and Advanced Virgo, Callister et al. [Phys. Rev. X 7, 041058 …
