The integration and verification phase of the GREGOR telescope reached an important milestone with the installation of the interim 1 m SolarLite primary mirror...
Gregor@night: The future high-resolution stellar spectrograph for the GREGOR solar telescope
We describe the future night-time spectrograph for the GREGOR solar telescope and present its science core projects. The spectrograph provides a 3-pixel...
This paper describes the main characteristics of GRIS (GREGOR Infrared Spectrograph), the grating spectrograph installed in the recently inaugurated (May 2012)...
High-resolution maps of the spiral galaxies NGC 3992 and NGC 4321, obtained with the Taurus camera at the 4.2-m William Herschel Telescope are analyzed. The...
High resolution Michelson interferometer for airborne infrared astronomical observations. I - Concept and performance
A Michelson interferometer has been built for use with the 91-cm telescope on NASA's Gerard P. Kuiper Airborne Observatory primarily to measure IR line emission...
We present here the outline of the process that any potential GTC observer will need to follow in order to perform their observations. Depending on which of the...
Image reconstruction with analytical point spread functions
Context. The image degradation produced by atmospheric turbulence and optical aberrations is usually alleviated using post-facto image reconstruction techniques...
