Birth and Evolution of Fast Radio Bursts: Strong Population-Based Evidence for a Neutron-Star Origin

Understand

While the appeal of their extraordinary radio luminosity to our curiosity is undiminished, the nature of fast radio bursts (FRBs) has remained unclear.

• The challenge has been due in part to small sample sizes and limited understanding of telescope selection effects.
• We here present the first inclusion of the entire set of one-off FRBs from CHIME/FRB Catalog 1 in frbpoppy.
• Where previous work had to curate this data set, and fit for few model parameters, we have developed full multi-dimensional Markov chain Monte Carlo (MCMC) capabilities for frbpoppy -- the comprehensive, open-science FRB population synthesis code -- that allow us to include all one-off CHIME bursts.
