Story summary

Seven new quasar candidates acting as strong gravitational lenses have been identified.
Researchers used machine learning and data from the Dark Energy Spectroscopic Instrument (DESI) to analyze over 812,000 quasars and achieve 99% accuracy.
These lenses advance the study of the co-evolution of supermassive black holes and their host galaxies.
The method enables measuring host-galaxy masses despite quasar brightness and thereby enhances understanding of the universe's history.
