We examine the evolution of the black hole mass-stellar velocity dispersion (M BH-σ)
relation over cosmic time, using simulations of galaxy mergers that include feedback from …

By" atmospheric tomography" we mean the estimation of a layered atmospheric turbulence
profile from measurements of the pupil-plane phase (or phase gradients) corresponding to …

Unsteady wind loads due to turbulence within the telescope enclosure are one of the largest
dynamic disturbances for ground-based optical telescopes. The desire to minimize the …

Large, high-bandwidth deformable mirrors (DMs) with thousands of actuators for adaptive
optics are of high interest for existing large telescopes and indispensable for construction of …

SCHOTT produces the zero expansion glass ceramics material ZERODUR since 35 years.
More than 250 ZERODUR mirror blanks were already delivered for the large segmented …

SCHOTT has a history of more than 35 years with the production of the zero expansion glass
ceramic material ZERODUR. More than 250 ZERODUR mirror blanks were already …

The Thirty Meter Telescope project is designing a 30m diameter ground-based optical
telescope. Unsteady wind loads on the telescope structure due to turbulence inside the …

Thirty Meter Telescope (TMT) will see its first light in 2018. We propose Second-Earth
Imager for TMT (SEIT) as a possible next generation instrument of TMT. The main purpose of …

ELTs will need large optical lenses for imaging optics and atmospheric dispersion
correctors. The extreme dimensions of lenses considered in designs at present (up to 1.7 m …
