The repository is no longer available. <<<!!!<<< 2018-08-29: no more access to GAPHYOR >>>!!!>>> Important note: The database was no longer feeded with data or updated in the years 2005-2007. The financial support of the project had been stopped a few yers ahead that time. The maintainance of the IT system couldn't be ensured anymore and system was shutdown in 2015. Please see the other databases in the field.
The Square Kilometre Array (SKA) is a radio telescope with around one million square metres of collecting area, designed to study the Universe with unprecedented speed and sensitivity. The SKA is not a single telescope, but a collection of various types of antennas, called an array, to be spread over long distances. The SKA will be used to answer fundamental questions of science and about the laws of nature, such as: how did the Universe, and the stars and galaxies contained in it, form and evolve? Was Einstein’s theory of relativity correct? What is the nature of ‘dark matter’ and ‘dark energy’? What is the origin of cosmic magnetism? Is there life somewhere else in the Universe?
>>>!!!<<< 2019-12-03: The repository is no longer available >>>!!!<<< Please use https://www.cfa.harvard.edu/amp/ampdata/kurucz23/sekur.html The atomic line data used in this database are taken from Bob Kurucz' CD-ROM 23 of spectroscopic line calculations. The database contains all lines of the file "gfall.dat" with the following items for each line: Wavelength; loggf; element code; lower level: energy, J, configuration; upper level: energy, J, configuration; gamma r; gamma s; gamma w; reference code. CD-ROM 23 has all the atomic line data with good wavelengths in one large file and in one file for each species. The big file is also divided into 10 nm and 100 nm sections for convenience. Also given are hyperfine line lists for neutral Sc, V, Mn, and Co that were produced by splitting all the energy levels for which laboratory data are available (only a small fraction).
This database gives values of the basic constants and conversion factors of physics and chemistry resulting from the 2002 least-squares adjustment of the fundamental physical constants as published by the CODATA Task Group on Fundamental Constants and recommended for international use by CODATA.
Nuclear Data Services contains atomic, molecular and nuclear data sets for the development and maintenance of nuclear technologies. It includes energy-dependent reaction probabilities (cross sections), the energy and angular distributions of reaction products for many combinations of target and projectile, and the atomic and nuclear properties of excited states, and their radioactive decay data. Their main concern is providing data required to design a modern nuclear reactor for electricity production. Approximately 11.5 million nuclear data points have been measured and compiled into computerized form.
AtomDB is an atomic database useful for X-ray plasma spectral modeling. The current version of AtomDB is primarly used for modeing collisional plasmas, those where hot electrons colliding with astrophysically abundant elements and ions create X-ray emission. However, AtomDB is also useful when modeling absorption by elements and ions or even photoionized plasmas, where X-ray photons (often from a simple power-law source) interacting with elements and ions create complex spectra.
The ADAS Project is a self-funding (i.e. funded by participants) project consisting of most major fusion laboratories along with other astrophysical and university groups. As an implementation, it is an interconnected set of computer codes and data collections for modelling the radiating properties of ions and atoms in plasmas. It can address plasmas ranging from the interstellar medium through the solar atmosphere and laboratory thermonuclear fusion devices to technological plasmas. ADAS assists in the analysis and interpretation of spectral emission and supports detailed plasma models.
