The Optical Gravitational Lensing Experiment. The Optical Depth to Gravitational Microlensing in the Direction of the Galactic Bulge
Andrzej Udalski,Michał K. Szymański,Krzysztof Z. Stanek,Krzysztof Z. Stanek,Janusz Kaluzny,M. Kubiak,Mario Mateo,Wojtek Krzeminski,Bohdan Paczynski,R. Venkat +9 more
TL;DR: In this paper, the first two years of the OGLE search for gravitational lenses towards the Galactic bulge were analyzed. And they found that the optical depth to microlensing is larger than 3.3 ± 1.2 × 10−6.

Cluster AgeS Experiment: The Age and Distance of the Globular Cluster ω Centauri Determined from Observations of the Eclipsing Binary OGLEGC 17
I. B. Thompson,I. B. Thompson,Janusz Kaluzny,Wojtek Pych,G. S. Burley,Wojtek Krzeminski,Bohdan Paczynski,S. E. Persson,George W. Preston +8 more
TL;DR: In this paper, the authors used photometric and spectroscopic observations of the detached eclipsing binary OGLEGC 17 to derive the masses, radii, and luminosities of the component stars, and then used these estimates to calculate the age and distance of the globular cluster ω Cen.

Cluster AgeS Experiment: The Age and Distance of the Globular Cluster omega Centauri Determined from Observations of the Eclipsing Binary OGLEGC17
Ian B. Thompson,Janusz Kaluzny,Wojtek Pych,G. S. Burley,Wojtek Krzeminski,Bohdan Paczynski,S. E. Persson,George W. Preston +7 more
TL;DR: In this article, the age and distance of OGLEGC17 were estimated by using the infrared surface brightness versus color relation and the Teff versus B-V color relation of Sekiguchi & Fukugita (2000).

The Optical gravitational lensing experiment. OGLE 7: Binary microlens or a new unusual variable?
Andrzej Udalski,Michał K. Szymański,Shude Mao,R. Di Stefano,Janusz Kaluzny,M. Kubiak,Mario Mateo,Wojtek Krzeminski +7 more
TL;DR: In this paper, the authors presented the light curve of OGLE #7, an unusual variable object, detected during the OGLE search for microlensing events, and showed that the star brightened by more than 2~mag with a characteristic double-maximum shape and returned to normal brightness after 60 days.
