BNL Cosmology and Astrophysics Group

We are a small group within the high-energy physics arm of the Physics Department at BNL working data analysis and theory in observational cosmology: how to measure and constrain properties of dark matter, dark energy and the standard cosmological model. We are members of DES, BOSS and LSST experiments. We collaborate closely with the BNL Instrumentation Division.

We also host a small project, Quantum Astrometry, to explore ideas on quantum-enhanced optical interferometry to improve the astrometrical precision.

The group has a Wiki located at
We organize the Joint Stony Brook - BNL Cosmology Seminar.
