The GRB Prompt Emission: An Unsolved Puzzle

Round 1

Reviewer 1 Report

Please state clearly the aims and timeliness of this review.  Why is such a review needed now?  

Author Response

We attempted to provide an overview on prompt emission of gamma-ray bursts in view of the forthcoming multiwavelength data and the currently planned future missions.  The aim was to discuss the models for prompt emission and associated physical processes together with the observational constraints. The expectation is that the new GeV/TeV data, the improved spectral and temporal coverage at lower frequencies, and inputs from other multi-messenger facilities such as Einstein Telescope and IceCube-Gen2, will provide new constraints for theoretical models.  We described a status of the theoretical modelling (within the limitations given by the length of the review), and the key problems in the production of gamma-rays, like the energy dissipation process, dynamics of the relativistic outflow, dominant radiation mechanism or particle acceleration. We outlined the long-standing problems in GRB physics, and the perspective given  with the upcoming observations.  We have added a few more references: in polarisation section, at the end of magnetically dominated jet section, and one reference on the backscattering photospheric model. All changes are marked in bold.

Reviewer 2 Report

The work is very well written and offers a review on the prompt emission interpretation and on the difficulty to fit with a simple Band function.

I spotted just one typo in the figure caption related to puctuation.

For me the paper can be accepted the way it is.

Thank you very much for your positive reply. 

Could you please let us know about the typo in the figure caption,  as we did not spot it?
