What are the two known sources of gamma ray bursts?
The intense radiation of most observed GRBs is thought to be released during a supernova or superluminous supernova as a high-mass star implodes to form a neutron star or a black hole. A subclass of GRBs (the “short” bursts) appear to originate from the merger of binary neutron stars.
How are gamma rays produced Class 10?
Gamma rays are generated in the decomposition of radioactive atomic nuclei and in the decay of definite subatomic particles. Nuclear reactions such as fusion, fission, alpha decay and gamma decay. Nuclear fusion is a reaction that powers the sun and stars.
What are gamma rays BYJU’s?
Gamma rays or gamma radiation is a stream of the high-energy electromagnetic radiation given off by an atomic nucleus undergoing radioactive decay.
What are the types of gamma-ray bursts?
Two types of GRBs When astronomers looked at the number of bursts versus how long they lasted, they found two different classes of bursts: long-duration and short-duration. These two classes are likely created by different processes, but the end result in both cases is a brand new black hole.
Which of these is a possible source of gamma-ray bursts that astronomers have observed using space based telescopes?
The explanation astronomers have in mind for the extra energy is the collapse of the star’s core to form a spinning, magnetic black hole or neutron star. Collisions among the particles in the beam can produce intense bursts of energy that we see as a gamma-ray burst.
How are gamma ray produced?
Gamma rays originate from the settling process of an excited nucleus of a radionuclide after it undergoes radioactive decay whereas X-rays are produced when electrons strike a target or when electrons rearrange within an atom.
Who discovered gamma?
Paul Villard
Gamma radiation is one of the three types of natural radioactivity discovered by Becquerel in 1896. Gamma rays were first observed in 1900 by the French chemist Paul Villard when he was investigating radiation from radium [1]. They are emitted by a nucleus in an excited state.
