The Department of Physics & Astronomy Colloquium Speaker Series / Comprehensive Exam presents “Spatial-Spectral Interferometry and Detector Technology in the Far-infrared” with PhD student, Chris Benson, University of Lethbridge.
Thursday, Feb. 11, 2021 9 to 10:15 a.m.
ONLINE ZOOM: https://uleth.zoom.us/j/99069795964
The Unique capabilities of FIR-astronomy to study the formation of planetary systems and galaxy spectra at the peak of cosmological star formation are limited by the performance of single-aperture space telescopes and direct detector sensitivity. In this colloquium, I will discuss the work being done within the Astronomical Instrumentation Group at the University of Lethbridge to study the application of spatial interferometry techniques for a space-based far-infrared observatory. Spatial interferometry has the capability to provide a dramatic increase in the spatial resolution of space-based far-infrared telescopes. My discussion will include a description of far-infrared direct detection technology as it pertains to transition edge sensing (TES) superconducting bolometers. I will also overview the experiments underway to characterize the novel bank of TES detectors employed by the far-infrared double-Fourier interferometer testbed that is being constructed to study interferometry techniques.
This is a FREE event and everyone is welcome.
