Keck Observatory on Maunakea are part of a team that came across a very rare find nestled billions of light years away that could help to quantify the universe. Researchers discovered a dozen “quadruply imaged quasars,” and only 50 “quads” have been found within the past 40 years. Quasars...

Caltech: Seeing Quadruple

Share Machine-learning methods lead to discovery of rare “quadruply imaged quasars” that can help solve cosmological puzzles With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic “lens” and split into four similar images. Quasars are extremely luminous cores of distant galaxies that are powered by supermassive black holes. Over the past four decades, astronomers had found about 50 of these...

Seeing Quadruple

Date Time Seeing Quadruple With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic “lens” and split into four similar images. Quasars are extremely luminous cores of distant galaxies that are powered by supermassive black holes. Over the past four decades, astronomers had found about 50 of these “quadruply imaged quasars,” or quads for short, which occur when the gravity of a massive galaxy ...
