Long GRB 250916A: an Off-axis Powerlaw Jet with Thermal Cocoon
Dit artikel analyseert GRB 250916A en concludeert dat het een off-axis powerlaw-jet is met een thermische cocoon, waarbij de voorloperemissie voortkomt uit een shockbreakout en een lange rustperiode wijst op een tijdelijke uitschakeling van de centrale motor.
