A team of astronomers found twelve quasars coated with natural “lenses” and divided into four identical images.
Quasars are the brightest particles of distant galaxies provided by large black holes.
This rare discovery increases the number of quasars or quads known by about 25% and can help determine the growth rate of the universe and help to deal with other mysteries.
Four-dimensional quasars are rare, and the first quadruple image was discovered in 1985.
Forty years ago, astronomers discovered about “four-dimensional quasars” or short quads, which happened when the gravitational force of a giant galaxy that sat in front of a quasar split its image into four, the Department of Science and Technology (DST) said.
A study by the Gaia Gravitational Lenses Working Group (GraL) for astronomers, which included scientists from the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, the DST institute, which lasts only a year and a half, demonstrates machine-learning abilities to assist astronomers in their search. these are cosmic values.
The study was approved for publication in ‘The Astrophysical Journal’, says DST.
“Quads are a gold mine for all kinds of questions. They can help determine the growth rate of the universe and help solve other mysteries, such as blacks and quasar ‘main engines’,” said Daniel Stern, lead author of a new study and research scientist at Jet Propulsion Laboratory USA.
