The College of Liberal Arts' University Forum lecture series presents "Seeing the Invisible in Space: Non-Optical Measurements in Astronomy" a talk by Paul La Plante, Postdoctoral Researcher, University of Pennsylvania.
This presentation explores two contemporary telescopes that observe the cosmos without using optical light. The Laser Interferometer Gravitational-Wave Observatory (LIGO), which won the 2017 Nobel Prize in Physics, detects gravitational waves emitted by black holes and neutron stars. The Hydrogen Epoch of Reionization Array (HERA) is a telescope that measures a radio signal emitted by gas between galaxies. Both instruments represent unique ways to complement optical observations and broaden our understanding of our place in the Universe.
