Physics and Astronomy Colloquium

Michael Zemcov, Rochester Institute of Technology. Measuring the Largest Structures in the Universe with the Smallest Telescopes in Space

Abstract: Observational astrophysics has frequently been driven by the need for ever increasing angular resolution, which has resulted in larger and more expensive telescopes. However, telescopes with very small apertures can sometimes perform cosmological measurements as important as their larger siblings. In this talk, I will present several examples of small aperture, space-based experiments providing unique views of the large scale structure of the Universe. In this talk, I will present recent results from the Cosmic Infrared Background Experiment (CIBER) that has successfully measured the amplitude of the near-IR background fluctuations on arcminute scales, and our recent work using the Long Range Reconnaissance Imager (LORRI) on New Horizons to measure the cosmic optical background.  I will also discuss the future of this field with a discussion of SPHEREx, a mid-class NASA Explorer mission designed to probe the inflationary history of the Universe and the evolution of galaxies, and SPECLE, a proposed CubeSat-class mission designed to measure the integrated emission from nucleosynthesis in the Universe.
