Search for lensed QSOs in the OGLE-IV survey

We present the results of our search for gravitationally lensed quasars in the OGLE survey. We show one best candidate from a 670 square degrees area behind the Magellanic Clouds System. The study of strong lensing time delays serves as a powerful probe in cosmology. The OGLE database provides long time light curves, allowing for a cost-effective way to accurately derive time delays and therefore study the Hubble constant.
