Linear polarization in gamma-ray burst prompt emission
Ramandeep Gill, Jonathan Granot, Pawan Kumar
Despite being hard to measure, GRB prompt -ray emission polarization is a valuable probe of the dominant emission mechanism and the outflow's composition and angular structure.…
The maximum luminosity of fast radio bursts
Wenbin Lu, Pawan Kumar
Under the assumption that fast radio bursts (FRBs) are from coherent curvature emission powered by the dissipation of magnetic energy in the magnetosphere of neutron stars, we pred…
Fast radio burst source properties from polarization measurements
Wenbin Lu, Pawan Kumar, Ramesh Narayan
Recent polarization measurements of fast radio bursts (FRBs) provide new insights on these enigmatic sources. We show that the nearly 100% linear polarization and small variation o…
Observational evidence for the formation of trapping horizons in astrophysical black holes
Raúl Carballo-Rubio, Pawan Kumar, Wenbin Lu
Black holes in general relativity are characterized by their trapping horizon, a one-way membrane that can be crossed only inwards. The existence of trapping horizons in astrophysi…
Radio emission from the cocoon of a GRB jet: implications for relativistic supernovae and off-axis GRB emission
Fabio De Colle, Pawan Kumar, David R. Aguilera-Dena
Relativistic supernovae constitute a sub-class of type Ic supernovae (SNe). Their non-thermal, radio emission differs notably from that of regular type Ic supernovae as they have a…
On the Missing Energy Puzzle of Tidal Disruption Events
Wenbin Lu, Pawan Kumar
For the majority of the tidal disruption event (TDE) candidates, the observed energy in the optical/near-UV bands is of order 10^{51} erg. We show that this observed energy is smal…
