This paper is concerned with the extrapolation of the dynamic response of the primary mirror of current 10-meter class telescopes to the next generation of 30 to 40 m extremely large telescopes and future, even larger, ones. A numerical study is cond

Telescope structures are traditionally built out of steel. To improve the possibility of realizing the ambitious extremely large telescopes, materials with a higher specific stiffness and a lower coefficient of thermal expansion are needed. An import

The European Southern Observatory (ESO) together with external research institutes have built a Multi-Conjugate Adaptive Optics (MCAO) Demonstrator (MAD) to perform wide field-of-view adaptive optics correction (2′ in K band). The aim of MAD is to

A programme has been started to investigate photon properties that are not currently exploited in astronomical instruments, namely second- and higher-order coherence functions encoded in their arrival time, and the orbital angular momentum. This pape

Current astronomical instrumentation essentially exploits only spatial or temporal coherence properties of the incoming photon stream. However, beyond this first-order coherence, and encoded in the arrival times of the individual photons, information

In the great majority of the cases, present astronomical observations are realized analyzing only first order spatial or temporal coherence properties of the collected photon stream. However, a lot of information is "hidden" in the second and higher
