Constraints on the central engine of merger-driven long gamma-ray bursts

Muskan Yadav, Roberto Ricci, Paz Beniamini +4

Recent observations have identified a new class of long-duration gamma-ray bursts (GRBs) likely produced by compact binary mergers. Using radio observations and lightcurve modellin…
