FRB 20210601A: Extreme Temporal Clustering in a Repeating Fast Radio Burst Source as Evidence for a Hidden Class of Episodic Repeaters

Ryan Mckinven, Amanda M. Cook, Alice P. Curtin +29

Population studies of fast radio burst (FRB) repetition typically model sources using a single distribution of steady, time-averaged burst rates, yet individual sources show signif…

A spatially resolved view of Fast Radio Burst host metallicities with Integral-field Spectroscopy

Sunil Simha, Hsiao-Wen Chen, Wen-fai Fong +15

Magnetar sources are the leading theory for Fast Radio Burst (FRB) progenitors. If magnetars are indeed the dominant sources, we may thus expect any metallicity preference for magn…

Fast radio burst dispersion is an unbiased tracer of matter on large scales

Shion Andrew, Haochen Wang, Kiyoshi Masui +6

The dispersion of fast radio bursts (FRBs) measures the column density of free electrons, tracing the diffuse ionized gas that contains more than of all baryons. On linear s…

FRB scattering statistics through the CGM are sensitive to morphology and intermittency

Dylan L. Jow, Calvin Leung

The small-scale properties of circumgalactic gas in ordinary galaxies drive its bulk properties: the mass loading of cold neutral gas in galactic outflows affects their bulk moment…

Nulling baryonic feedback in weak lensing surveys using cross-correlations with fast radio bursts

Calvin Leung, Josh Borrow, Kiyoshi W. Masui +4

Baryonic feedback is a leading contaminant in studying dark matter and cosmology using cosmic shear. This has meant omitting much of the data during cosmological inference, or forw…

Accretion from a Shock-Inflated Companion: Spinning Down Neutron Stars to Hour-Long Periods

Savannah Cary, Wenbin Lu, Calvin Leung +1

Recent observations have unveiled a population of pulsars with spin periods of a few minutes to hours that lie beyond the traditional ``death line.'' If they originate from neutron…
