WebGamma-Ray Bursts October 15, 2009 Astronomy Astrophysics A star exploded just 625 million years after the Big Bang, but the radiation of this event didn’t reach Earth until last spring. This gamma-ray burst was named GRB 090423. It is the most distant astronomical object yet discovered. WebMar 23, 2024 · Gamma rays are energy that has no mass or charge. Gamma rays have tremendous penetration power and require several inches of dense material (like lead) to shield them. Gamma rays may pass all the way through a human body without striking anything.

WebApr 11, 2024 · We study the radio galaxies with known redshifts detected by the Fermi satellite after 10 yr of data (4FGL-DR2). We use a one-zone leptonic model to fit the quasi-simultaneous multiwavelength data of these radio galaxies and study the distributions of the derived physical parameters as a function of black hole mass and accretion disk luminosity.

Someone probably has them compiled somewhere, too. If your source is purely Eu-152, then use the relative instensities and the areas of the matching energy peaks to develop an efficiency vs energy graph. game of familia raw
