		BOHDAN PACZYNSKI: If gamma ray bursts were in our Galaxy they should be distributed the way everything is distributed now our Galaxy which means they should be near the galactic plane and possibly also concentrated towards the galactic centre.
		BOHDAN PACZYNSKI: Gamma ray bursts were coming to us from all over the sky with no particular relation to our galactic plane or the galactic centre and in fact that is what I saw in the data.
		BOHDAN PACZYNSKI: I think that was professionally the most joyous moment in my life because all of a sudden I realised that something which was very risky, which could work either way, turned out my way, so of course I was very, very happy.

	Princeton - Weekly Bulletin 4/15/02 - Paczynski 'OGLEs' the sky for answers to cosmic questions
		Astrophysics professor Bohdan Paczynski, pictured here near the observatory on the roof of Peyton Hall, is part of a group that has pioneered a method of surveying large patches of sky.
		Paczynski realized that scanning for flickers among stars might reveal an effect called gravitational lensing in which the gravity of a massive body bends light that passes by.
		Paczynski argued that they emanated from the very edge of the visible universe, an idea that was ultimately vindicated by recent observations.

		In 1991, Bohdan Paczynski of Princeton University, an OGLE team member, proposed using gravitational microlensing to detect planets.
		Paczynski says the microlensing technique will likely yield more planet discoveries within the year, and he predicts that over the next few years they may even find Earth-sized planets around distant stars.
		Paczynski says multiple planetary systems can in principle be detected with this method, but since finding even one planet is such a difficult task, he doesn't think finding multiple planets around one star is likely.

	ASP: 2002 Award Winners Press Release
		San Francisco, Calif. – The Astronomical Society of Pacific (ASP), one of the world’s oldest and largest astronomy organizations, is proud to announce that astrophysicist Bohdan Paczynski of the Princeton University Observatory is the 2002 winner of its prestigious Bruce Gold Medal.
		Paczynski (pronounced pah-CHIN-skee) is recognized by the ASP for his revolutionary work in many fields of astronomy.
		Paczynski also helped develop the leading model to explain most gamma-ray bursts: that these extraordinarily powerful explosions result when massive stars collapse to form fl holes.

		But Paczynski calculated that a much smaller mass could focus light from a single background star and make it look brighter on Earth, just as a flashlight lens makes the light from a small bulb appear brighter.
		Paczynski thinks there are so many in that direction because the bulge is shaped like a bar that points toward us--something astronomers have suspected for 30 years.
		Thus in the end, Paczynski's technique may help answer two of the greatest questions in astronomy--the nature of the dark matter and the existence of Earth-like planets outside the solar system.

	Extrasolar planet - Wikipedia, the free encyclopedia
		This method is most fruitful for planets between earth and the center of the galaxy, as the galactic center provides a large number of background stars.
		In 1986, Bohdan PaczyÅski of Princeton University first proposed using it to look for mysterious dark matter, the unseen material that is thought to dominate the universe.
		Successes with the gravity lensing method date back to 2002, when a group of Polish astronomers ( Andrzej Udalski, Marcin Kubiak and MichaÅ SzymaÅski from Warsaw, and Bohdan PaczyÅski) during project OGLE (the Optical Gravitational Lensing Experiment) perfected a workable method.

		In a 1986 paper, Paczynski proposed a clever technique that has already given astronomers their first probe of dark matter.
		Paczynski is affiliated with a second group, based primarily in Poland, called OGLE, short for Optical Gravitational Lensing Experiment.
		To further complicate things, there is the chance—which Paczynski thinks quite possible, Alcock very much less so—that most of the microlensing events have not been caused by objects in the Galaxy's dark halo.

	Discover: It turns out they're truly titanic - research and theories on gamma-ray bursts
		In the mid-1980s, though, a Princeton astronomer named Bohdan Paczynski pointed out that they seemed to be coming from all directions in the sky, in which case their sources must be evenly distributed, too.
		Comets being way too cold to emit gamma rays, Paczynski advocated the latter hypothesis -- that the bursts came from far away, which meant their energy must be preposterously large.
		"At first," recalls Fishman, "Bohdan was the only one who took that position." So few bursts had been observed at the time that their distribution was still debatable.
