Physics Represents UNT at the 241st American Astronomical Society Meeting

The University of North Texas had an impressive presence at this year's 241st meeting of the American Astronomical Society (AAS) in Seattle, WA, which took place January 8-12, 2023. UNT Physics' students and faculty presented several talks and electronic posters, as well as advertised the department's new TEXAS Bridge Program, which is supported by the National Science Foundation.

"Our participation at the meeting this year is a testament to the growth and prominence of astrophysics in the UNT Physics Department," said Dr. Ohad Shemmer, Associate Professor of UNT Physics. Until about ten years ago, Dr. Shemmer had been the only UNT participant in the AAS.

"Our previous record of eight people in attendance was at the 235th meeting of the AAS in Honolulu in 2020," he said. "This year, after a three-year hiatus due to COVID, we broke the previous record and hosted nine people from UNT, with many more presentations."

Those in attendance included UNT faculty members Drs. Ohad Shemmer, Yuan Li, and Rebekah Purvis. They were joined by postdoctoral scholar Shalini Ganguly; graduate students Cooper Dix, Trung Ha, Andrea Marlar, and Brandon Matthews; and undergraduate Mirielle Caradonna.
