Judd Bowman's 'The Dawn of a New Era in Cosmology' Lecture

Join Arizona State University's School of Earth and Space Exploration for Judd Bowman's upcoming New Discoveries lecture: "The Dawn of a New Era in Cosmology."

About the Speaker: 

Judd Bowman is an experimental cosmologist interested in the formation of structure in the early universe including the first stars, galaxies and black holes. His current research focuses on the development and deployment of technologies and techniques to enable observational probes of the redshifted 21 centimeter line of neutral hydrogen gas during the epoch of reionization. Much of Professor Bowman's data collection takes place in the outback of Western Australia and in other remote sites around the world where interference from human-generated radio sources like FM radio and TV stations is greatly reduced.

About the Lecture:

When was the first star born?  What happened when it died?  These are two questions on the cutting edge of astrophysics, where astronomers try to understand how the universe developed from the Big Bang, about 13.8 billion years ago, to today. 
 
But studying the earliest stars is extraordinary difficult. We normally see our universe through starlight: even the most distant galaxies observed by the Hubble Space Telescope are collections of stars. To study the earliest stars in the universe, which probably began shining before the universe was 100 million years old, astronomers must look very far away — so far away that the light from the stars themselves is likely too faint for optical telescopes ever to capture.
 
I will talk about efforts led by ASU astronomers to get around this limitation and open an entirely new window on the early universe. With collaborators around the world, we have designed and are now operating new radio telescopes that look for the collective fingerprints of the first stars in the primordial gas left over after the Big Bang.
 
Like a cosmic crime scene, the first clues are just emerging and the mystery may be stranger than we expected!

FAQs

What are my parking options?

The Marston Exploration Theater is located on the first floor of ASU's Interdisciplinary Science and Technology Building IV (ISTB 4), the home of the School of Earth and Space Exploration. ISTB 4 (map) is located near the intersection of Rural and Terrace Road in Tempe on the east side of campus. This seven-story structure is ASU’s largest research facility, and is accessible on foot via Orange Street and McAllister Avenue If arriving by Light Rail, exit at the "University and Rural Road" stop.

Parking is available inside the Rural Road parking structure just east of ISTB 4. From the parking structure, walk west and enter ISTB4 through the glass doors on the north side of the building. Please note that a parking fee is $3 per hour and is charged upon exiting the parking structure. There is additional pay parking directly south of ISTB4 available for $2 per hour. There is an automated payment registration kiosk on the parking lot's west side (the corner near the building).

Do I need to arrive early?

Guests are recommended to show up by 7:15 p.m. to gain entry into the theater. At 7:30 p.m. any seats will be released to first come/first served at the door.

Where can I contact the organizer with any questions?
