GRB 161219B-SN 2016jca: a powerful stellar collapse

Long duration gamma-ray bursts (GRBs) mark the birth of a compact object, a neutron star or black hole. At low-redshift (z<0.2) these events are extremely rare and most are poorly known. Four nearby GRBs have been associated with Type Ic supernovae (SNe Ic), . GRB/SNe lack hydrogen and helium, and... Show more
