About

Giovanni Pareschi is a leading figure in X-ray optics for space-based astrophysics, specializing in the design, alignment, and integration of advanced telescope mirrors. His primary research focuses on enabling high-resolution, large-effective-area X-ray telescopes through innovative technologies like slumped borosilicate glass and Silicon Pore Optics (SPO). Pareschi has made pivotal contributions to the development of the ATHENA (Advanced Telescope for High-ENergy Astrophysics) mission, ESA’s next large-class X-ray observatory. His work on the integration facility for ATHENA’s mirror assembly—a process involving hundreds of co-aligned SPO modules—has been critical to achieving the mission’s ambitious angular resolution and sensitivity goals. With over 50 citations across his most-cited papers, his research has shaped the path from early concepts like XEUS to the current ATHENA design. Notably, his 2013 paper on accurate integration of segmented X-ray optics using interfacing ribs (21 citations) and his leadership in developing the ATHENA optics integration facility underscore his impact. Pareschi’s efforts are essential for future missions seeking to probe the hot, energetic Universe, making him a key contributor to next-generation space observatories.
