The Department of Physics & Astronomy hosts guest speaker Dr. Phillip M. Korngut ’05, Scientific Researcher in Observational Cosmology in the Division of Physics, Mathematics and Astronomy at California Institute of Technology. The title of his presentation is “SPHEREx: An All-Sky Near Infrared Spectroscopic Survey.”
This lecture is free and open to the public, and will be presented as a Zoom webinar; please register in advance to receive login information.
The Spectro Photometer for the History of the universe, Epoch of Reionization and Ices Explorer (SPHEREx) is a Midex-class NASA mission currently in the implementation phase. By utilizing a wide field, low temperature telescope in concert with a series of linear variable filters (LVFs), SPHEREx will produce a near infrared spectrum for every pointing on the celestial sphere. This unique dataset will yield a three dimensional map of the large scale structure of the universe which can harbour an imprint from cosmic inflation, 10^-32 seconds after the big bang. Additionally, the SPHEREx design is optimized to quantify the fluctuations in the cosmic infrared background, and to survey the plane of our Galaxy for water and other biogenic ices. In this talk, I will give an overview of these science goals as well as the instrument and mission designs necessary to achieve them.
