About

A. Zambra is a leading figure in the development of advanced X-ray optics, with a primary focus on the fabrication and integration of segmented, lightweight mirror systems for next-generation space telescopes. His most cited work, "Accurate integration of segmented x-ray optics using interfacing ribs" (2013, 21 citations), addresses a critical challenge in astrophysics: building telescopes that combine a large effective area with high angular resolution (e.g., 5 arc sec HEW) while remaining lightweight and cost-effective. Zambra’s key contribution lies in perfecting the slumping of borosilicate glass sheets and the precise integration of these segments using interfacing ribs, a technique that enables the production of low-cost, high-performance mirrors. This work is foundational for future missions requiring long focal lengths and unprecedented sensitivity. Beyond this, Zambra has contributed to the broader field of X-ray optics through studies on mirror alignment and thermal stability. His research is instrumental in advancing the technological readiness of segmented optics, directly supporting the design of flagship observatories like ATHENA. With a growing citation impact, Zambra is recognized as a key innovator in making high-resolution X-ray astronomy more accessible and affordable.
