The RAR model was obtained in a self-gravitating system of fermions "Inos", to account for the dark matter (DM) distribution in galaxies, providing thus degenerated quantum cores of mpc sizes with constant densities and expected core halos of the order of kpc, both in agreement with astrophysical data. Based on this configuration, we compute...

GRB 190114C is the first binary-driven hypernova (BdHN) fully observed from the initial supernova appearance to the final emergence of the optical SN signal. It offers an unprecedented testing ground for the BdHN theory and it is here determined and further extended to additional gamma-ray bursts (GRBs). BdHNe comprise two subclasses of long...

On 2018 July 28, GRB 180728A triggered Swift satellites and, soon after the determination of the redshift, we identified this source as a type II binary-driven hypernova (BdHN II) in our model. Consequently, we predicted the appearance time of its associated supernova (SN), which was later confirmed as SN 2018fip. A BdHN II originates in a...

Recently we proposed the existence of two families of short GRBs, both originating from neutron star mergers: family-1 short bursts with Eiso < 1052 erg and rest-frame spectral peak energy Epeak < 2 MeV, leading to a massive neutron star as the merged core; family-2 short bursts with Eiso > 1052 erg and Epeak > 2 MeV, leading to a black hole as...

For short gamma-ray bursts (GRBs), double neutron star (NS) mergers are traditionally adopted as progenitors. We propose a classification of short bursts into two sub-classes: short gamma-ray flashes (S-GRFs) with isotropic energy Eiso ≲ 1052 erg and rest-frame spectral peak energy Ep,i ≲ 2 MeV, when the merger leads to a very massive NS (MNS),...

We review our recent results on the classification of long and short gamma-ray bursts (GRBs) in different subclasses. We provide observational evidences for the binary nature of GRB progenitors. For long bursts the induced gravitational collapse (IGC) paradigm proposes as progenitor a tight binary system composed of a carbon-oxygen core...

Short and long-duration gamma-ray bursts (GRBs) have been recently sub-classified into seven families according to the binary nature of their progenitors. For short GRBs, mergers of neutron star binaries (NS–NS) or neutron star-black hole binaries (NS-BH) are proposed. For long GRBs, the induced gravitational collapse (IGC) paradigm proposes a...
