Assessment of the Cherenkov camera alignment through Variance images for the ASTRI telescope
Experimental Astronomy - Tập 53 - Trang 117-132 - 2021
A peculiar aspect of Cherenkov telescopes is that they are designed to detect atmospheric light flashes on the time scale of nanoseconds, being almost blind to stellar sources. As a consequence, the pointing calibration of these instruments cannot be done in general exploiting the standard astrometry of the focal plane. In this paper we validate a procedure to overcome this problem for the case of......
Perspectives and challenges for future telescopes
Experimental Astronomy - Tập 26 - Trang 201-210 - 2009
At the celebration of 400 years of telescopic observations, it is appropriate to consider future ground-based facilities enabled by continuing technological developments, and driven by astronomical questions which are amongst the most fundamental in science and are of enormous interest to the general public.
EChO spectra and stellar activity – I
Experimental Astronomy - - 2014
Stellar activity is the major astrophysical limiting factor for the study of planetary atmospheres. Its variability and spectral characteristics may affect the extraction of the planetary signal even for moderately active stars. A technique based on spectral change in the visible band was developed to estimate the effects in the infrared due to star activity. This method has been purposely develop......
Backprojection mechanisms in phase-closure imaging. Bispectral analysis of the phase-restoration process
Experimental Astronomy - Tập 1 - Trang 47-76 - 1989
The minimum-norm least-squares solution of the phase-closure equations of an interferometric array is very stable. Furthermore, this canonical solution can be obtained by simple backprojection, each closure phase leaving its “algebraic” imprint on the corresponding baselines. More precisely, the generalized inverse of the phase-closure operator C of an n-point array is equal to its adjoint (its He......
Analytical fitting of $$\gamma $$ –ray photopeaks in germanium cross strip detectors
Experimental Astronomy - - Trang 1-18 - 2023
In an ideal germanium detector, fully-absorbed monoenergetic
$$\gamma $$
–rays will appear in the measured spectrum as a narrow peak, broadened into a Gaussian of width determined only by the statistical properties of charge cloud generation and the electronic noise of the readout electronics. Multielectrode d......
Orbit determination methods for interplanetary missions: development and use of the Orbit14 software

A revision of soft proton scattering at grazing incidence and its implementation in the geant4 toolkit
Experimental Astronomy - Tập 44 - Trang 401-411 - 2017
The scattering of soft protons inside the Wolter-type optics of X-ray observatories has been proven to concentrate these particles onto the focal plane instruments. The funneling of these protons increases the instrumental background and can also contribute to the degrading of the detectors. The instrumental background and degradation of the detector’s performance experienced by Chandra and XMM-Ne......
