Constraining the FRB mechanism from scintillation in the host galaxy
Pawan Kumar, Paz Beniamini, Om Gupta +1
Most FRB models can be divided into two groups based on the distance of the radio emission region from the central engine. The first group of models, the so-called `nearby' or magn…
Hybrid Pulsar-Magnetar Model for FRB 20191221A
Paz Beniamini, Pawan Kumar
We show that the 216.80.1 ms periodicity reported for the fast radio burst (FRB) 20191221A is very constraining for burst models. The high accuracy of burst periodicity (bette…
Gravitational lensing in the presence of plasma scattering with application to Fast Radio Bursts
Pawan Kumar, Paz Beniamini
We describe how gravitational lensing of fast radio bursts (FRBs) is affected by a plasma screen in the vicinity of the lens or somewhere between the source and the observer. Wave…
Transparency of Fast Radio Burst Waves in Magnetar Magnetospheres
Yuanhong Qu, Pawan Kumar, Bing Zhang
At least some fast radio bursts (FRBs) are produced by magnetars. Even though mounting observational evidence points towards a magnetospheric origin of FRB emission, the question o…
The plasma suppression effect can be ignored in realistic FRB models invoking bunched coherent radio emission
Yuanhong Qu, Bing Zhang, Pawan Kumar
One widely discussed mechanism to produce highly coherent radio emission of fast radio bursts (FRBs) is coherent emission by bunches, either via curvature radiation or inverse Comp…
On explaining prompt emission from GRB central engines with photospheric emission model
Mukul Bhattacharya, Pawan Kumar
Although the observed spectra for gamma-ray burst (GRB) prompt emission is well constrained, the underlying radiation mechanism is still not very well understood. We explore photos…
