It marks the second major Chandra program led by Antoniou, who is also a research associate with the Smithsonian Astrophysical Observatory.Each year, astronomers from around the world follow a rigorously competitive process to receive Chandra time. The telescope was launched aboard the space shuttle Columbia in 1999 and orbits Earth, offering previously unavailable views of deep space at wavelengths that are not accessible from ground telescopes.
Antoniou, also the director of the Preston Gott Skyview Observatory about 15 miles north of Lubbock, was awarded one mega-second of Chandra telescope time, which equates to roughly 11.5 days . “Chandra’s proposal selection process is highly competitive, and Vallia’s research program was the only VLP approved out of nine submitted in Cycle 24,” said Sung-Won Lee, chair of the physics and astronomy department. “This project is an international collaboration of scientists, and I am very pleased that our very own faculty is recognized internationally and will lead this important scientific mission.
