The RANICON for Ground Based Optical Astronomy
1988We have developed a versatile 2D photon counting imaging system that determines the location and arrival time of a detected photon with high precision and reliability. It makes use of a standard proximity focused semi-transparent photocathode to convert photons to electrons, coupled to a cascaded stack of microchannel plates acting as the position ...

Ground Based Astronomy with Adaptive Optics
2000Adaptive optics for astronomy has been under intensive development for a decade now. Numerous facilities are in or near operation. The performance of ground based natural guide star systems is fairly well understood, and laser beacon development has made enormous progress also.

Neural nets for ground-based γ-ray astronomy
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2003Abstract The application of the artificial neural networks to data processing in the domain of the atmospheric Cherenkov γ-ray telescopes is considered. The main problems arising from the specifics of these experiments, such as low signal, pairs of ON–OFF observations, instability of the background events, and their influence on the analysis are ...

Ground-based gamma-ray astronomy: General remarks
Il Nuovo Cimento C, 1996The ground-based gamma-ray astronomy has its coming of age currently with 4 sources detected at high significance levels, after experiencing about 30 years history. The energetic gamma rays provide direct means for uncovering higher-energy non-thermal phenomena at various celestial objects.

The future of ground-based gamma-ray astronomy
Rendiconti Lincei. Scienze Fisiche e Naturali, 2019Ground-based gamma-ray astronomy is a young branch of high-energy astrophysics, addressing the highest energies in the electromagnetic spectrum. TeV photons cannot be produced by “ordinary” stars since they require quite extreme conditions, thus they allow the study of extreme astrophysical objects such as supernova remnants, neutron stars, black holes,

Background Modeling in Ground Based Cherenkov Astronomy
2005Ground based Cherenkov telescope systems measure astrophysical γ-rayemission against a background of cosmic ray induced air-showers. The subtraction of this background is a major challenge for the extraction of the spectra and morphology of gamma-ray sources.
