No Strong Evidence for Plasma Lensing in FRB 20240114A
Jiarui Niu, Xiaohui Liu, Nan Xu +33
FRB~20240114A is an extremely active repeating fast radio burst for which plasma lensing has been proposed to explain its burst-rate variations, spectral evolution, and apparently…
Constraining the near-source relativistic wind medium using Fast Radio Burst circular polarization data
Om Gupta, Pawan Kumar, Paz Beniamini
Fast Radio Bursts (FRBs) exhibit diverse spectro-temporal characteristics, which can probe vital propagation and source physics via Stokes polarimetry. We investigate whether the c…
The kinetic-energy bottleneck in Fast Radio Burst models
Paz Beniamini, Pawan Kumar
Most Fast Radio Burst (FRB) models invoke a two-step process in which energy released by the central engine is converted into particle kinetic energy and only subsequently radiated…
Asking Fast Radio Bursts for More than Reionization History
Abinash Kumar Shaw, Raghunath Ghara, Paz Beniamini +2
We propose different estimators to probe the intergalactic medium (IGM) during epoch of reionization (EoR) using the dispersion measure () of the fast radio bursts. We co…
Can repeating and non-repeating FRBs be drawn from the same population?
Paz Beniamini, Pawan Kumar
Do all Fast Radio Burst (FRB) sources repeat? We present evidence that FRB sources follow a Zipf-like distribution, in which the number density of sources is approximately inversel…
The Cosmic Evolution of Fast Radio Bursts Inferred from the CHIME/FRB Baseband Catalog 1
Om Gupta, Paz Beniamini, Pawan Kumar +1
Redshift and luminosity distributions are essential for understanding the cosmic evolution of extragalactic objects and phenomena, such as galaxies, gamma-ray bursts, and fast radi…
