Interests:

Nagy’s research group focuses on experimental cosmology, probing the evolution and composition of the Universe by building microwave telescopes and analyzing the resulting data.

Precision measurements of the Cosmic Microwave Background (CMB) radiation are continuing to transform our understanding of the Universe.  Emitted just a few hundred thousand years after the Big Bang, the CMB photons are influenced by the structure and contents of the Universe and even carry a record of events that occurred before they were formed.    Measuring the characteristics of the CMB thus allows us to use the Universe as a laboratory, exploiting the cumulative interactions of the photons over vast distances and cosmic timescales to amplify small effects.

Nagy’s lab designs and builds instruments to enable more precise measurements of the CMB. Her group works on a combination of balloon-borne and ground-based telescopes, including SPIDER, Taurus, and CMB-S4.Together these experiments probe topics including the physics of inflation, the optical depth to reionization, and the properties of fundamental particles.  In the lab, her group works on many different aspects of instrumentation including low temperature detectors, optics, and calibration as well as data analysis.
