Professor Shaul Hanany of the School of Physics and Astronomy is part of a collaboration that has created a new optical device that will improve the performance of telescopes studying the Cosmic Microwave Background (CMB), a relic remnant radiation from the Big Bang. Physicists study the CMB to understand the physics of the Big Bang and the evolution and properties of the Universe. The optical device makes telescopes operating at the wavelengths of the CMB more efficient. Hanany was joined by his former Ph.D. student,  Tomotake Matsumura (Ph.D. Physics '06) now a faculty member at the Kavli Institute for the Physics and Mathematics of the Universe, which is part of the University of Tokyo.
