About

G. Tagliaferri is a leading figure in the development of advanced X-ray optics for next-generation space telescopes. His primary research focuses on the fabrication and integration of lightweight segmented mirrors, particularly using slumped borosilicate glass sheets—a technology critical for achieving the large effective areas and high angular resolution required by future X-ray observatories. His most cited work (21 citations) introduces an innovative method for precisely integrating these fragile glass segments using interfacing ribs, directly addressing the challenge of maintaining a 5 arc sec half-energy width (HEW) while minimizing mass and cost. This contribution is foundational to the design of long-focal-length telescopes like those proposed for the Athena mission. Tagliaferri’s expertise in optical metrology and assembly processes has made him a key collaborator on international projects, where his solutions for aligning and bonding thin mirror segments help push the boundaries of what is possible in high-energy astrophysics. His work enables the construction of telescopes that can capture faint cosmic sources with unprecedented clarity.
