. The gravitational instability - is the increasing of the perturbation of the density and the velocity under the gravitational force influences. The results of the gravitational instability are the cluster of substances. The gravitational instability is a cause of generation of many astronomical objects (stars, galaxies, etc). Back .

Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...
RUSSIAN . The Centre for Astronomical Data (CAD) of the Institute of Astronomy (INASAN) of the Russian Academy of Sciences was established in 1980 as a branch regional center of the Centre de Donnes Stellaire (CDS) with the purpose of astronomical data dissemination among Soviet and Eastern Europe astronomers and for providing the CDS with Soviet machine readable astronomical catalogues. The CAD archive is based on astronomical catalogues received from Strasbourg since 1980. ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
