SUMMARY:Dr. Yue Yu – The International Axion Observatory (IAXO)
DESCRIPTION:\nTHE CLASSROOM WILL BE OPEN FOR THIS EVENT\nJoin us in the WAS Classroom for this lecture with Columbia’s Dr. Yue Yu who will join us in person. This event will be live-streamed on YouTube and as a webinar on Zoom, but we’d love to see you in the classroom at the Westport Observatory. As always, the talk will be posted to the Westport Astronomical Society’s YouTube channel afterwards.\nX-ray telescopes for the International Axion Observatory (IAXO) and the next generation of solar axion searches\n\nAxions and axion-like particles (ALPs) are among the most compelling candidates for dark matter. Our sun serves as a natural axion factory, where a reservoir of the photons in the solar core is converted into abundant axions, offering a promising approach to search for axions. When the solar axions escape the Sun and stream towards Earth, ground-based axion helioscopes reconvert the axions into X-ray photons. Focusing X-ray telescopes concentrate the X-ray photons onto a small, low- noise detector area, constituting a key component for enhancing detection sensitivity.\n\n\n\n\n\n\nThis talk will introduce an overview of the next-generation helioscope experiment, the International Axion Observatory (IAXO), and its pathfinder, BabyIAXO. It will also cover the design and development of one of the BabyIAXO inner core X-ray telescopes, including its optical performance requirements, fabrication challenges and implementation strategies.\n\n\nDr. Yue Yu completed her Ph.D. in physics at Tongji University, after receiving her bachelor’s degree from Ocean University of China. She is currently a postdoctoral research scientist in the Columbia Astrophysics Laboratory, working with Prof. Kerstin Perez.\nHer research focuses on the development of X-ray and extreme ultraviolet (EUV) optical systems for astronomical and astrophysical observations. She works across the full development cycle of optical instrumentation—including optical design, characterization, and commissioning—at both component and system levels. At present, she is leading the development of the X ray inner core optics for the International Axion Observatory (IAXO) project.\n \n\n\n****\nThe February Cal’s Corner will feature an “attractive” object.\n
