Selected topics on: (1) proposal of interpreting the Crab supernova with a GRB (2) progress in identifying the seven GRBs episodes (3) the role of Sagittarius a in identifying the dark matter component (the X-fermion)

As the 50th anniversary of our common effort in the field of relativistic astrophysics is approaching, we offer a new look to some of our acquired knowledge in a more complete view, which evidence previous unnoticed connections. They are gaining due prominence in reaching a more complete picture evidencing the main results. We outline the history of GRB observations along with a summary of the contributions made by our group to develop the BdHN interpreting model. We show the seven episodes characterizing the most powerful BdHNe I occurred to date: GRB 190114C and GRB 220101A. New inferences for the explanation of the highest energy radiation in the TeV are presented.
