GRB 201216C: MAGIC Detects Farthest GRB at VHE energies

GRB 201216C, a long GRB, was observed by numerous instruments, including Swift-BAT, Fermi-GBM, and the MAGIC telescopes. MAGIC detected GRB 201216C at a redshift of z = 1.1, making it the farthest known source detected at VHE gamma rays. Modeling of GRB 201216C's multiwavelength data, including the MAGIC observations, favors a scenario where the GRB jet is expanding into a wind-like medium shaped by the progenitor star. This is consistent with the observed light curves and SEDs. Publication: H.
