DOI: 10.1103/physrevd.104.084012
Abstract: We present the first application of a hierarchical Markov Chain Monte Carlo (MCMC) followup on continuous gravitational-wave candidates from real-data searches. The follow-up uses an MCMC sampler to draw parameter-space points from the posterior distribution,… read more here.
