Exploring the epoch of hydrogen reionization using FRBs

Paz Beniamini, Pawan Kumar, Xiangcheng Ma +1

We describe three different methods for exploring the hydrogen reionization epoch using fast radio bursts (FRBs) and provide arguments for the existence of FRBs at high redshift (z…

Fast Radio Burst Dispersion Measure Distribution as a Probe of Helium Reionization

Mukul Bhattacharya, Pawan Kumar, Eric V. Linder

Fast radio burst (FRB) discoveries are occurring rapidly, with thousands expected from upcoming surveys. The dispersion measures (DM) observed for FRB include important information…

What does FRB light-curve variability tell us about the emission mechanism?

Paz Beniamini, Pawan Kumar

A few fast radio bursts' (FRBs) light-curves have exhibited large intrinsic modulations of their flux on extremely short (s) time scales, compared to pulse durat…

A unified picture of Galactic and cosmological fast radio bursts

Wenbin Lu, Pawan Kumar, Bing Zhang

The discovery of a fast radio burst (FRB) in our galaxy associated with a magnetar (neutron star with strong magnetic field) has provided a critical piece of information to help us…

Radiation Forces Constrain the FRB Mechanism

Pawan Kumar, Wenbin Lu

We provide constraints on Fast Radio Burst (FRB) models by careful considerations of radiation forces associated with these powerful transients. We find that the induced-Compton sc…

FRB Coherent Emission from Decay of Alfven Waves

Pawan Kumar, Z. Bosnjak

We present a model for FRBs where a large amplitude Alfven wave packet is launched by a disturbance near the surface of a magnetar, and a substantial fraction of the wave energy is…
