Formation rate (FR) history of extragalactic sources provide crucial information on how the universe emerged from the dark ages to its current stage. Best observed FR is that of stars (SFR) that rises from high redshifts to redshift of ~3 and declines to today. Active galactic nuclei (AGNs) show a similar trend but with different parameters. Transient sources like gamma-ray bursts (GRBs), and...

60. The case of GRB 220101A: the first example of a GRB triggered by two Supernovae 14.7 s apart

We investigate GRB 220101A provides , the first of a new family of long GRBs exceeding a total energy of 10^54 erg, within a newly modified BdHN model. Its exceptional luminosity is explained by a pair-supernova triggering the event, followed after ∼ 7 minutes by an induced core-collapse supernova. What makes GRB 220101A so exceptional is: (1) its redshift z = 4.61, and (2) the high-quality...

36. Physics of GRB afterglows: new insights from TeV observations

Recent observations of several Gamma-Ray Burst (GRB) afterglows in the TeV domain have profoundly impacted the theory of particle acceleration and radiation in relativistic shocks. We can now confidently state that the Synchrotron-Self-Compton (SSC) model for afterglow emission has successfully passed experimental verification. Furthermore, simultaneous multi-wavelength observations --...
