Happy New Year! And welcome to Volume 5 of the FRB Community Newsletter. We are starting off the year with a large haul of papers, including one reporting the discovery of an interesting binary pulsar system with a companion mass in the apparent gap between neutron star and black hole masses. We hope you enjoy the issue, and as always, we welcome your tips, announcements, and other items of possible interest.

• A pulsar in a binary with a compact object in the mass gap between neutron stars and black holes; Barr et al., Science, DOI: 10.1126/science.adg3005; arXiv: 2401.09872

  "The companion to the pulsar is a compact object and its mass (between 2.09 and 2.71 solar masses, 95% confidence interval) is in the mass gap, so it either is a very massive NS or a low-mass BH. We propose the companion was formed by a merger between two earlier NSs."
