Search for Gravitational Lensing from a Survey of Highly Luminous Quasars
Abstract
The authors have shown that their search for gravitational lensing from a survey of optically selected highly luminous quasars (HLQ) appears very promising. Observational features (multiple images, image elongation, jet-like feature, fuzz, etc.) possibly associated with the HLQ phenomenon have been detected for more than 20% of the objects under study. While it is not yet known how many of the HLQs are gravitational mirages, at least 5 (out of 111) of the investigated quasars appear to be highly luminous because of amplification of their brightness by gravitational lensing.
