The paper reviews the evidence linking gamma-ray bursts (GRBs) to core-collapse supernovae (SNe), a connection that has emerged from observations and theoretical models. It discusses the growing body of evidence suggesting that most long-duration soft-spectrum GRBs are accompanied by massive stellar explosions (GRB-SNe). These GRB-SNe are found to have greater kinetic energy and luminosity than ordinary SNe, but there is also evidence for considerable diversity in their properties. The energy in the explosion is primarily contained in nonrelativistic ejecta rather than in the relativistic jets responsible for the burst and its afterglow. The paper explores the implications of this association, including the role of differential rotation in the collapsing iron core of massive stars as a potential distinguishing factor between SNe and GRBs. It also discusses the observational evidence for the SN-GRB connection, the characteristics of GRB-SNe, and the future directions in this field.The paper reviews the evidence linking gamma-ray bursts (GRBs) to core-collapse supernovae (SNe), a connection that has emerged from observations and theoretical models.
