	Warsaw Voice - Copernicus Would Be Proud
		Andrzej Udalski of the Warsaw University Astronomical Observatory has been carrying out the Optical Gravitational Lensing Experiment (OGLE) for several years now.
		Udalski's team has firmly placed Poles in the leading position of astronomy since the historic achievements of Nicholas Copernicus.
		Udalski's solution was supplemented by computer software created especially for this project.

	Size of universe tops astronomy agenda (Site not responding. Last check: 2007-10-10)
		Hubble astronomer Edward Guinan, from Villanova University in Philadelphia, and Warsaw, Poland-based researcher Andrzej Udalski presented results from their study of a pair of stars orbiting one another in the Large Magellanic Cloud (LMC), a satellite galaxy of our own Milky Way.
		The distance from Earth to the LMC is a cosmic meter stick that establishes the zero point of the Hubble constant, H, which appears in all calculations used to determine the size and age of the universe.
		Udalski and Guinan produced data that show both the sizes and temperatures of the two stars.

		Andrzej Udalski from Astronomical Observatory of the Warsaw University was awarded by the Foundation for revising the scale of distances in the Universe and discovering numerous dark objects accompanying stars.
		In mid-2001 Andrzej Udalski constructed a technologically advanced camera, which substantially increased the effectiveness of Polish telescope located in Chile.
		He was also the instigator of using the Polish telescope for the search of low weight elements in the Universe, which is one of the most important pressing hypothesis of contemporary astrophysics.

		The key person is Andrzej Udalski, who made the currently used 2k x 2k CCD camera with a thin SITe device with 24 micron pixels, corresponding to 0.4" in the sky.
		Udalski will build a mosaic 8k x 8k CCD camera using thin SITe CCDs, with 15 micron pixels (0.25" in the sky).

	Princeton - Weekly Bulletin 4/15/02 - Paczynski 'OGLEs' the sky for answers to cosmic questions
		Earlier this year, the group, including Princeton graduate student Przemyslaw Wozniak and the lead member of the team in Poland, Andrzej Udalski of Warsaw University, published a free Internet database of 250,000 variable stars from a survey conducted from 1997 to 1999.
		Astronomers have found that they can use lensing and other flickering events to calculate very accurately the distances and sizes of faraway objects, which can then be used as a yardstick for calibrating other cosmic features such as the shape and distribution of mass in our galaxy, said Tremaine.
		Udalski, who founded OGLE with Paczynski, has even used the data to propose a recalibration of the basic measure by which astronomers gauge the size of the universe.

	Amateur and professional astronomers team to find new planet
		The new planet and its star compose one of the most distant worlds ever found by man. Gravitational microlensing offers unique advantages for astronomers hunting planets: not only can it find more distant worlds than previously used techniques, but microlensing also is more sensitive to smaller worlds.
		The microlensing event was detected and observed by the Optical Gravitational Lensing Experiment, or OGLE, led by Andrzej Udalski of Warsaw University.
		Two other collaborations - the Probing Lensing Anomalies NETwork (PLANET) and Microlensing Observations in Astrophysics (MOA) - also followed the event and contributed to the journal paper.

		Here on Earth, we see the star get brighter as the lens crosses in front of it, and then fade as the lens gets farther away.
		On March 17, 2005, Andrzej Udalski, professor of astronomy at Warsaw University and leader of the Optical Gravitational Lensing Experiment, or OGLE, noticed that a star located thousands of light years from Earth was starting to move in front of another star that was even farther away, near the center of our galaxy.
		A month later, when the more distant star had brightened a hundred-fold, astronomers from OGLE and from Gould's collaboration (the Microlensing Follow Up Network, or MicroFUN) detected a new pattern in the signal -- a rapid distortion of the brightening -- that could only mean one thing.
