Astronomers have tested the Perseus galaxy cluster in search of an undetected particle that would assist in supporting string theory.
String theory is the idea that of all known forces, particles and interactions could be connected via a single framework to understand the physical universe. A group of astronomers using NASA’s Chandra X-ray Observatory studied galaxy clusters — the largest structures in the universe held together by gravity — for indicators of an ultra-low-mass particle referred to as an axion, which many models of string principle predict ought to exist.
Axion particles are believed to have incredibly low lots, potentially starting from a millionth of the mass of an electron down to zero mass. The crew further regarded for indicators of “axion-like particles” that are a broader class of extremely-low-mass particles with similar properties to axions, based on the statement.
Moreover, these extremely-low-mass particles might sometimes turn into photons — the particles that make up light — after they pass by magnetic fields. In turn, photons may also turn into axions under specific conditions. Each scenario depends upon the mass of the particles and the way easily they can make the conversion, also known as convertibility, based on the assertion.
As a part of this new study, astronomers utilizing the Chandra space telescope studied the spectrum of X-ray emissions produced by material falling in direction of the supermassive black gap at the center of the Perseus galaxy cluster.
One attainable explanation for these recent observations is that the particles have both a lower or higher convertibility than the Chandra space telescope is able to detect, the researchers stated.
