Statistics of the Optical Turbulence from the Micrometeorological Measurements at the Baykal Astrophysical Observatory Site

Atmosphere, 2019
The paper focuses on the investigations of the optical turbulence structure. The distributions of the repeatability of the structure characteristic of the air refractive index are obtained. A scenario of decreasing the intensity of the optical turbulence

Active Optics in Astronomy: Freeform Mirror for the MESSIER Telescope Proposal

Mathematical and Computational Applications, 2018
Active optics techniques in astronomy provide high imaging quality. This paper is dedicated to highly deformable active optics that can generate non-axisymmetric aspheric surfaces—or freeform surfaces—by use of a minimum number of actuators ...

STAGES:the Space Telescope A901/2 Galaxy Evolution Survey [PDF]

, 2008
We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution across a wide range of environments and luminosity.

Implementation of a spherical double-plasma-mirror telescope for a multi-petawatt laser

High Power Laser Science and Engineering
High-power laser beamlines typically operate with fixed focusing conditions, limiting the focal spot size and peak intensity. To mitigate these restrictions, prior studies used curved plasma mirrors to adjust the F-number to a specific value.

The prototype Schwarzschild Couder Telescope: A Medium-Sized Telescope for the Cherenkov Telescope Array

EPJ Web of Conferences, 2023
The Schwarzschild-Couder Telescope (SCT) is a dual-mirror telescope designed for the Cherenkov Telescope Array Observatory (CTAO) to observe very-high-energy gamma rays (20 GeV to 300 TeV). It features a dualmirror system and a high-resolution camera with an 8° field of view (FoV) for enhanced angular resolution and background rejection.
