Description
In this talk, I will highlight some of the recent and most exciting theoretical and observational development in gamma-ray bursts (GRBs) that occured in the past decade, alongside some new open questions that I anticipate would be at the forefront of GRB reserch in the next decade. In particular, I will discuss our current state of knowledge on: (1) jet structure, which became evident following GRB/GW170817; (2) the on-going debate about the orign of TeV emission, as was seen in few GRBs; (3) The ~10 MeV emission line seen in the BOAT GRB 221009A, and its implication on the prompt emission physics; (4) polarization measurements that show discrepancy between theory and data; and finally (5) indication that in many GRBs, the Lorentz factor is only a few tans, rater than few hundreds.
