The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...

RELATIVE SUNSPOT NUMBERS Description of Data from SGD Explanation of Data Reports: Relative Sunspot Numbers -- The relative sunspot number is an index of the activity of the entire visible disk of the Sun. ...

Waldmeier of the Swiss Federal Observatory. ... This indicates the uncertainty above and below the predicted number. ...

... Тhis new concept touches our simple lives, yet for those intrigued by the natural sciences, especially experts deeply engaged in the 'eternal' questions of general geology and astronomy, it is all the more fascinating. The problems to be faced by any theory for the formation of the Solar System . Any theory has to account for certain rather tricky facts about the Solar System. These are in addition to the obvious facts that the Sun is at the centre with the planets in orbit around it. ...

EVOLUTION OF GALACTIC DISCS: TWO MODES OF STAR FORMATION ABSTRACT We develop the model of the evolution of surface gas density, stellar density, star formation rates and chemical composition of galactic disc taking into account the gravitational instability of rotating gaseous layer in the scales of several kpc. ... In the model we took into account the gas return from evolved stars, a radial movement of the gas in a spiral arms and accretion of the gas into the galactic disc. ...

... Printed in U.S.A. ( YOUNG STELLAR NUCLEI IN THE LENTICULAR GALAXIES. ... We пnd a rather young stellar nucleus, with a mean population age of 1.5 ^ 0.5 Gyr, which is more metal­rich than the bulge at RB 1 kpc by an order of magnitude. ... But the center of a galaxy is a special place ; the stellar nucleus may have a particular evolution that di+ers from the evolution of the whole galaxy. ... We have detected intermediate­age stellar popu­ lations in the centers of these galaxies. ...
