Unveiling the Mysteries of Cosmic Gamma Rays
The Fermi Gamma-Ray Space Telescope has changed how we see gamma-ray bursts. These are the most powerful explosions in space. They happen when black holes form or neutron stars merge. The Fermi GBM has found and pinpointed hundreds of these events, helping us learn about their nature and beginnings4.
The Fermi LAT also looks at high-energy particles like cosmic rays. These particles get super charged in places like supernovae, active galaxies, and our own galaxy4.
Understanding Gamma-Ray Bursts and High-Energy Particles
Recently, scientists found the brightest gamma-ray burst ever, called GRB 221009A4. This burst happened on October 9, 2022, and showed a new feature never seen before. The Fermi Gamma-ray Space Telescope found a high-confidence emission line in it, the first in 50 years4. Scientists also found a new high-energy feature linked to light-speed jets in this burst4.
This burst’s peak emission was about 12 MeV. It showed a pattern around 5 minutes after the event, lasting 40 seconds. The energy of visible light was between 2 and 3 MeV4. A collision between an electron and a positron can also create gamma rays with an energy of 0.511 MeV4.
The Fermi Gamma-ray Space Telescope was made by NASA’s Goddard Space Flight Center in Maryland. It’s a joint project with the U.S. Department of Energy and countries like France, Germany, Italy, Japan, Sweden, and the U.S4..
Recently, a study found the highest-energy gamma-ray line from space, at 37 million electron volts5. This discovery helps us understand gamma-ray bursts better. They are the most explosive events in the universe after the Big Bang5.
“The discovery of the brightest GRB, GRB 221009A, which occurred on October 9, 2022, was attributed to the collapse of a massive star.”5
A team led by Xiong Shaolin analyzed the burst GRB 221009A. They found power-law decay patterns and a constant, narrow line width during the burst5. China has launched satellites to study gamma-ray bursts, helping us understand the extreme universe5.
