New Research Suggests Long Gamma-Ray Bursts Originate from Collapsing Stars, Not Neutron-Star Mergers
Long-duration gamma-ray bursts are some of the most energetic events in the universe, releasing more energy in just a few seconds than the sun emits in 10 billion years. Los Alamos National Laboratory scientists, having discovered gamma-ray bursts more than 50 years ago, continue to add to the understanding of these mysterious events.
Scientists at Los Alamos National Laboratory are proposing a new theory regarding the origin of long-duration gamma-ray bursts (GRBs). These powerful cosmic events, which release immense energy in seconds, may actually stem from collapsing stars rather than the previously favored explanation of neutron-star mergers. The research builds upon decades of study since GRBs were first discovered over 50 years ago. This revised understanding could significantly alter astrophysical models of the universe's most energetic phenomena. The findings challenge existing theories and open new avenues for research into cosmic explosions.
This new hypothesis about the origin of long gamma-ray bursts could fundamentally change our understanding of the universe's most energetic events and stellar evolution.
