What are tightly focused beams of high-energy radiation linked to asymmetrical supernovae called?

Answer

Gamma-Ray Bursts (GRBs).

Core-collapse supernovae are spectacular explosions, but sometimes, under specific conditions such as asymmetrical collapse or rapid core rotation, the explosion channels its immense energy output into highly collimated jets. These jets consist of tightly focused beams of extremely energetic radiation, predominantly in the gamma-ray spectrum. These transient cosmic phenomena are known as Gamma-Ray Bursts (GRBs). When a GRB is directly linked to a core-collapse supernova event, the entire mechanism is often referred to as a collapsar event. These bursts rank among the most luminous electromagnetic events observed in the entire universe, briefly capable of outshining the total light output of the galaxy in which they occur.
