Ningfeng Zhu, Ph.D. candidate in the Department of Physics and Astronomy and member of the lab of Mark Devlin, Reese W. Flower Professor of Astronomy and Astrophysics, was lead author on a recent study published in The Astrophysical Journal Supplement Series detailing his and the Devlin Lab's work on the Large Aperture Telescope Receiver (LATR) "that will be the 'heart' of the Simons Observatory Large Aperture Telescope." The paper details "design considerations and how they struck a balance to achieve the technical specifications required" while the LATR is on Penn's campus. "The testing is still ongoing," Zhu told Penn Today. "We will receive more detectors to test, more components to integrate, and we will be gearing towards getting ready for shipment." The LATR is scheduled to be shipped to the Simons Observatory by early 2022.
