... Together, this small group works mostly in the field of Active Galactic Nuclei, exploring their distribution in parameter space (black hole mass, black hole spin, accretion rate) and their evolution in cosmic time. Since the growth and activity of the central black hole, on the one side, and the assembly of the host galaxy, on the other, go very tightly in parallel, the AGN evolution is a convenient window on the more general problem of the formation of cosmic structures. ...

Authors: Yu.G. Shevelev , V.A. Marsakov , . ... We have constructed and investigated properties of metallicity function of disk stars with different ages, proceeding from the statistically restored real altitude distributions of stars at the solar galactocentric distance. It is shown that the metallicity distribution of stars in each age range is not of Gaussian form, but it may be considered as a superposition of two normal distributions centered at -0.2 and 0.0 dex. ...

... One of the most widely used tools of Fourier analysis is the Parseval theorem. It enables the experimentalist to view how the `energy' in the signal is distributed among frequencies. The Fast Fourier Transform (FFT) algorithms have made power spectra one of the obvious diagnostics tools during data acquisition, and energy maps are a versatile alternative. ... The result is an energy map (Fig. 9), showing the distribution of energy corresponding to the wavelet map (Fig. ...
