This map describes the locations of millions of quasars spread across the vast universe.
Quasars’ dazzling brightness allows them to easily overshadow their host galaxy.Among them, the light from the furthest quasar is from when the universe was just 1.5 billion years old. For reference, the present age of the universe is 13.7 billion years.How ESA’s Gaia and stellar music help astronomers measure the universe
“It isn’t the catalog with the most quasars, and it isn’t the catalog with the best-quality measurements of quasars, but it is the catalog with the largest total volume of the universe mapped,” added Hogg who is a senior research scientist at the Flatiron Institute’s Center for Computational Astrophysics in New York City and a professor of physics and data science at New York University.Additional data was received from NASA’s Wide-Field Infrared Survey Explorer and the Sloan Digital Sky Survey.
“It has been very exciting to see this catalog spurring so much new science. Researchers around the world are using the quasar map to measure everything from the initial density fluctuations that seeded the cosmic web to the distribution of cosmic voids to the motion of our solar system through the universe,” said Storey-Fisher in theFor example, they compared the newly generated quasar map to the cosmic microwave background, which is the universe’s earliest detectable light.
