The Galaxy Evolution Probe: A Concept for a Mid- to Far-Infrared Survey Machine to Precisely Measure the Star Formation History, Growth of AGN, and Evolution of Galactic Interstellar Medium over Cosmic Time
Presented by Jason Glenn
NASA Goddard Space Flight Center

Thursday, October 1, 2020
Virtual Event starts at 11:00 A.M.

Abstract
Assembling a cosmic history of star formation, supermassive black hole growth, and the build-up of metals in galactic disks will require large infrared surveys that can see into the hearts of galaxies. The NASA Astrophysics Probe class under consideration by the Decadal Survey provides an opportunity to meet this challenge on a scope between MIDEXs and Flagship observatories. I will discuss the Galaxy Evolution Probe (GEP), a concept for an infrared observatory dedicated to large, uniform galaxy surveys. I will provide context on the complementarity of infrared observations to other wavelengths and surveys, describe the design of GEP with a brief focus on the enabling detector technology -- kinetic inductance detectors invented at JPL, and present predictions for science yields based on simulations. The GEP design study was funded by NASA and JPL was the design center.

About the Speaker
Dr. Glenn joined NASA Goddard as a research astrophysicist this year. Prior to that, he was a professor of astrophysics at the University of Colorado Boulder for 20 years, where he served as the director of the Center for Astrophysics and Space Astronomy for six years. Dr. Glenn's research interests include galaxy evolution and the interstellar medium in galaxies, and mid-infrared to millimeter-wave astronomical instrumentation and detector development.
