... Second, the observatory can control the configuration, test data analysis procedures, and provide calibration solutions with the help of instrument models. This paper presents the VLT object-oriented framework for the development of ETCs (Exposure Time Calculators) and data simulators. ... Instrument simulations are being developed for the purpose of predictive calibration, instrument configuration control, and evaluation of data analysis procedures. ...

... Archives . ... The PCA and ICA is used for separating mixed components with some assumptions. ... The need of source separation methods in astronomy has led various adaptations of decomposition methods available. ... I rarely come up with a paper which gathered and summarized component separation methods applicable to astronomical data. In that regards, the following paper seems useful to overview methods of reducing dimensionality for astronomers. [arxiv:0805.0269] . ... Chandra Blog . ...

... PPTA timeline . ... List of projects . ... However, our time series are not equally sampled, so classical spectrum analysis cannot be applied immediately. ... Normally when analysing time series with very steep spectra one would use a "prewhitening" technique and perhaps a low sidelobe spectral window (e.g. the Hanning window). ... The idea is to separate the steep and flatter spectrum components so they can be analysed separately. ... The upper panel has raw data, interpolated data and red...

The spectrophotometrical complex of the 6-m telescope in Nasmyth-1 focus . ... A new sample of 360 blue compact galaxies with a strong star formation was build on the base of the Second Byurakan Survey. ... More that 20 galaxies with the extremely low-abundances of heavy elements in the range of 1/30-1/10 of the Sun's one, were found. ... During the 15-years observation term near 500 spectra of the unique source SS~433, from which the relativistic jets were found for the first time, were obtained. ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...

Проект существует с июля 2002 года. Цель проекта - дать краткий обзор наиболее интересных статей, появившихся в библиотеке электронных препринтов astro-ph . Также в обзоры будут включаться статьи, появившиеся в списке astro-ph из других разделов. ... Параллельно в 2002-2003 гг. создавался списки обзорных статей, в которых подробно освещаются те или иные часто обсуждаемые вопросы (например, статья А. Линде hep-th/0107176 является одной из лучших обзорных статей по инфляции). ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
