Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they ...

Gamma ray emission causes no change in the number of particles in the nucleus meaning both the atomic number and mass number remain the same. All types of radioactive decay can be detected by a ...

In strong magnetic fields, axions should occasionally decay into photons, so detecting extra light ... the first 10 seconds ...

In 2019, the world was mesmerized by the first-ever image of a black hole, courtesy of the Event Horizon Telescope (EHT). The ...

M87 was the first black hole to be imaged, and now it's revealing details of how some elementary particles are accelerated by the universe's most extreme environments.

The 25 ground-based and orbiting telescopes that comprise the EHT saw the outburst as high-energy light called gamma rays. Not only was this the first time M87* had flared since 2010, but the ...

This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two ... on behalf of the U.S. Nuclear Data Program and Nuclear Structure and Decay Data network.

This database offers a variety of tables for all natural elements and includes the following data: isotopic composition, thermal radiative cross section (total and partial), Westcott g-factors, energy ...
