Probing AU-Scale Magnetic-Field Reversals in the Interstellar Medium with Pulsar Scintillation
Jacob Yen, Daniel Baker, Dongzi Li +1
AU-scale structures in the interstellar medium have become relevant across several areas of astrophysics, from ISM microphysics to pulsar timing arrays and cosmic-ray (CR) propagat…
Detection of Partial Coherence due to Multipath Propagation for FRB 20220413B with CHIME/FRB
Zarif Kader, Evan Davies-Velie, Matt Dobbs +7
Fast radio bursts (FRBs) are a millisecond-long transient phenomenon that propagate across extragalactic distances and are effectively a point source. Radio wave propagation…
Single Epoch Measurements of Dispersion Measure Gradients Towards PSR B0834+06
Daniel Baker, Ue-Li Pen
Understanding the evolution of pulsar dispersion measures is vital to high precision timing experiments, as well as astrometric experiments to determine pulsar positions and proper…
Echoes in Different Tempo: Long-Term Monitoring of Crab Echoes with CHIME
Thierry Serafin Nadeau, Marten H. van Kerkwijk, Jing Luo +4
The Crab Pulsar is known to feature plasma lensing events known as echoes. These events are characterized by additional components in the pulse profile which are produced by additi…
FRB 20250316A: A Brilliant and Nearby One-Off Fast Radio Burst Localized to 13 parsec Precision
FRB Collaboration, Thomas C. Abbott, Daniel Amouyal +83
Precise localizations of a small number of repeating fast radio bursts (FRBs) using very long baseline interferometry (VLBI) have enabled multiwavelength follow-up observations rev…
Scintillation Properties of PSR B1133+16 Measured with Very Long Baseline Interferometry
Ashley M. Stock, Fardin Syed, Marten H. van Kerkwijk +3
The scintillation of pulsars reveals small-scale structure of the interstellar medium. A powerful technique for characterizing the scintillating structures (screens) combines analy…
