How has the universe changed and evolved in the billions of years since the Big Bang? How do scientists learn about the early universe with telescopes? Join us for a 30-minute lecture about the history of the universe followed by a panel Q&A consisting of several astrophysicists to answer your questions about astronomy and space science.
This public astronomy event will be hosted both in-person as well as live-streamed over YouTube Live. The lecture will be 30 minutes, followed by a 90-minute session of telescope-aided stargazing and a Q&A Panel consisting of experts in the department on a variety of astronomy and astrophysical topics. You can attend in person or interact with us through the YouTube interface. Event is free and open to all, no reservations necessary.

Title: Uncovering the History of the Universe with Radio Astronomy
Lecturer: Ruby Byrne
Abstract:
Cosmology aims to explain the origins of our universe. Much like an archaeologist discovering artifacts from the distant past, observational cosmologists search for signals from space that are relics from our universe’s ancient history. In particular, we look for light from distant objects that was emitted millions or billions of years ago. In this talk, Dr. Ruby Byrne will describe how these observations inform our current understanding of the universe’s origins. She will describe how modern radio telescopes like the OVRO-LWA are continuing this legacy and helping fill in gaps in our cosmic history.
