CHIME/FRB Discovery of the Extremely Active Fast Radio Burst Source FRB 20240114A

The Astrophysical Journal
Among the thousands of observed fast radio bursts (FRBs), a few sources exhibit exceptionally high burst activity observable by many telescopes across a broad range of radio frequencies. Almost all of these highly active repeaters have been discovered by

Searching for Gamma-Ray Bursts Associated with the Second CHIME/FRB Catalog

The Astrophysical Journal
Fast radio bursts (FRBs) and gamma-ray bursts (GRBs) are both linked to compact-object activity, yet their possible connection remains unclear. Here we perform a systematic search for spatial and temporal associations between FRBs in the second CHIME/FRB

Simultaneous Multiwavelength Observations of the Repeating Fast Radio Burst FRB 20190520B with Swift and FAST

The Astrophysical Journal
Among several dozen known repeating fast radio bursts, those precisely localized offer the best opportunities to explore their multiwavelength counterparts, which are key to uncovering their origins.

Morphology of 137 Fast Radio Bursts Down to Microsecond Timescales from the First CHIME/FRB Baseband Catalog

The Astrophysical Journal
We present a spectro-temporal analysis of 137 fast radio bursts (FRBs) from the first CHIME/FRB baseband catalog, including 125 one-off bursts and 12 repeat bursts, down to microsecond resolution using the least-squares optimization fitting routine ...

Challenges for Fast Radio Bursts as Multimessenger Sources from Binary Neutron Star Mergers

The Astrophysical Journal
Fast radio bursts (FRBs) are millisecond-duration transients from extragalactic sources, with their origins remaining a topic of active debate. Among the proposed progenitors, binary neutron star (BNS) mergers are compelling candidates for some ...

Polarization Angle Geodesics in PSRs B1133+16 and B2016+28

The Astrophysical Journal
Recent models of pulsar polarization predict that the position and ellipticity angles of the polarization vector can trace portions of a small or great circle on the Poincaré sphere.

Proposed Host Galaxies of Repeating Fast Radio Burst Sources Detected by CHIME/FRB

The Astrophysical Journal
We present a search for host galaxy associations for the third set of repeating fast radio burst (FRB) sources discovered by the CHIME/FRB Collaboration. Using the ∼1′ CHIME/FRB baseband localizations and probabilistic methods, we identify potential host
