We report the milliarcsecond localization of a high (1379 pc/cc) dispersion measure (DM) repeating fast radio burst, FRB 20190417A. Combining European VLBI Network detections of fi…
Constraining the Faint-End Slope of the FRB Energy Function Using CHIME/FRB Catalog-1 and Local Volume Galaxies
Mohit Bhardwaj, Victoria M. Kaspi, K. W. Masui +3
Despite hundreds of detected fast radio bursts (FRBs), the faint-end slope () of their energy distribution remains poorly constrained, hindering understanding of whether bright,…
Final Moments III: Explosion Properties and Progenitor Constraints of CSM-Interacting Type II Supernovae
W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52
We present analysis of the plateau and late-time phase properties of a sample of 39 Type II supernovae (SNe II) that show narrow, transient, high-ionization emission lines (i.e., "…
A Catalog of Local Universe Fast Radio Bursts from CHIME/FRB and the KKO Outrigger
FRB Collaboration, Mandana Amiri, Daniel Amouyal +62
We present the first catalog of fast radio burst (FRB) host galaxies from CHIME/FRB Outriggers, selected uniformly in the radio and the optical by localizing 81 new bursts to 2'' x…
An Updated Detection Pipeline for Precursor Emission in Type II Supernova 2020tlf
Wynn Jacobson-Galán, Sebastian Gonzalez, Shreyas Patel +34
We present a new photometric pipeline for the detection of pre-supernova (pre-SN) emission in the Young Supernova Experiment (YSE) sky survey. The method described is applied to SN…
Morphology of 35 Repeating Fast Radio Burst Sources at Microsecond Time Scales with CHIME/FRB
Alice P. Curtin, Ketan R. Sand, Ziggy Pleunis +27
The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) project has discovered the most repeating fast radio burst (FRB) sources of any telescope. However,…
The Massive and Quiescent Elliptical Host Galaxy of the Repeating Fast Radio Burst FRB20240209A
T. Eftekhari, Y. Dong, W. Fong +39
The discovery and localization of FRB20240209A by the Canadian Hydrogen Intensity Mapping Fast Radio Burst (CHIME/FRB) experiment marks the first repeating FRB localized with the C…
PS1-11aop: Probing the Mass Loss History of a Luminous Interacting Supernova Prior to its Final Eruption with Multi-wavelength Observations
Adaeze L. Ibik, Maria R. Drout, Raffaela Margutti +14
Luminous interacting supernovae are a class of stellar explosions whose progenitors underwent vigorous mass loss in the years prior to core-collapse. While the mechanism by which t…
A search for persistent radio sources toward repeating fast radio bursts discovered by CHIME/FRB
Adaeze L. Ibik, Maria R. Drout, Bryan M. Gaensler +25
The identification of persistent radio sources (PRSs) coincident with two repeating fast radio bursts (FRBs) supports FRB theories requiring a compact central engine. However, deep…
Contemporaneous X-ray Observations of 30 Bright Radio Bursts from the Prolific Fast Radio Burst Source FRB 20220912A
Amanda M. Cook, Paul Scholz, Aaron B. Pearlman +22
We present an extensive contemporaneous X-ray and radio campaign performed on the repeating fast radio burst (FRB) source FRB 20220912A for eight weeks immediately following the so…
Final Moments II: Observational Properties and Physical Modeling of CSM-Interacting Type II Supernovae

We present ultraviolet/optical/near-infrared observations and modeling of Type II supernovae (SNe II) whose early-time ( days) spectra show transient, narrow emission lines…
A pulsar-like swing in the polarisation position angle of a nearby fast radio burst
Ryan Mckinven, Mohit Bhardwaj, Tarraneh Eftekhari +41
Fast radio bursts (FRBs) last for milliseconds and arrive at Earth from cosmological distances. While their origin(s) and emission mechanism(s) are presently unknown, their signals…
