What is Compact Dark Matter from Quasar Lensing about?

The document discusses the investigation of compact dark matter (DM) using time-varying quasar equivalent widths, focusing on the potential existence of compact baryonic objects like black holes. A sample of 777 quasars was analyzed, identifying 19 that exhibit evidence of lensing by compact objects with masses between 5 × 10−5 and 2 × 10−2 solar masses. This research aims to refine our understanding of dark matter by leveraging quasar spectra and their time variability to constrain theories regarding compa
