Long and short gamma-ray bursts (GRBs) are thought to arise from different and unrelated astrophysical progenitors.
The association of long GRBs with supernovae (SNe) and the difference in the distributions of galactocentric offsets of long and short GRBs within their host galaxies have often been considered strong evidence of their unrelated origins.
Long GRBs have been thought to result from the collapse of single massive stars, while short GRBs come from mergers of compact object binaries.
Our present study challenges this conventional view.
We demonstrate that the observational properties, such as the association with SNe and the different galactic offsets, are naturally explained within the framework of the binary-driven hypernova model, suggesting an evolutionary connection between long and short GRBs.
