Stakeholder Relations
We take great pride in being part of the Long Island community. We value the relationships that
we build together with our neighbors—relationships built by listening and speaking openly about the issues we all
care about. We know that the Laboratory's future as a world leader in science research depends on the trust and participation
of our neighbors.
Listening to You
The Community Advisory Council advises the Laboratory Director on issues that are important to the community. All meetings are open to the public. Learn more about the Council. Do you have an issue you'd like to raise, a question that you'd like to ask? Let us know!
About Us
Brookhaven scientists conduct research in the physical, biomedical, and environmental sciences, and in energy technology and national security. The Laboratory is among the five largest high-technology employers on Long Island. More...
Economic Impact
At a time when New York's state economy depends on its capacity for
innovation, Brookhaven Lab represents a uniquely valuable resource —
both as a major science-based enterprise in its own right, and as a
source of the scientific discovery and technological innovation on which
growth depends.

Physics Department Summer Lecture Series
"Using Gravitational Lensing to measure Dark Matter and Dark Energy in the Universe"
Presented by Erin Sheldon, BNL
12:30 pm, Small Seminar Room, Bldg. 510
Friday, June 28, 2019, 12:30 pm
Hosted by: Mary Bishai
Gravitational lensing is the bending of the path of light near massive bodies. Mass produces a curvature of space time, and light follows a curved path that is calculable using the General Theory of Relativity. I will discuss how the lensing effect is used to measure the amount of Dark Matter in galaxies and in the universe as a whole. I will also discuss how we use lensing to measure the properties of the mysterious Dark Energy that is driving the accelerated expansion of our universe.
