Welcome to another issue of the FRB Newsletter, where one of your editors is reporting live from the Multiwavelength Follow-Up of FRBs workshop in Toronto, Canada. As usual, we welcome your pointers to publications, conference announcements, job listings, and other items that might be relevant to our 700+ readers! Meanwhile, we hope you enjoy this round-up.

• The Northern Cross Fast Radio Burst project -- III. The FRB-magnetar connection in a sample of nearby galaxies; Pelliciari et al., arXiv: 2304.11179

Theory and Modeling

• Deja-vu et Deja-entendu: Associating fast radio bursts with compact binary mergers via gravitational lensing; Singh et al., arXiv: 2304.02879

• Neutron star phase transition as the origin for the fast radio bursts and soft gamma-ray repeaters of SGR J1935+2154; Shen et al., arXiv: 2304.10871

Algorithms and Instrumentation

• Processing System for Coherent Dedispersion of Pulsar Radio Emission; Girin et al., arXiv: 2303.17280
• TONE: A CHIME/FRB Outrigger Pathfinder for localizations of Fast Radio Bursts using Very Long Baseline Interferometry; Sanghavi et al., arXiv: 2304.10534
• The Large Array Survey Telescope -- System Overview and Performances; Ofek et al., arXiv: 2304.04796

Magnetars and other relevant results

• Coherent radio bursts from known M-dwarf planet host YZ Ceti; Pineda & Villadsen, arXiv: 2304.00031
• Disentangling the Faraday rotation sky; Hutschenreuter et al., arXiv: 2304.12350

• Ongoing FAST monitoring of FRB 20121102A shows that the rotation measure continues its steady decline. The authors report an observed RM of 3.1E4 rad m^-2, implying an average annual decline of 1E4 rad m^-2 per year since 2019 (ATel 15980, 15981).
