1. Observations and Reduction
... Blue compact galaxies HS 1013+3809 (KUG 1013+381) and HS 1442+4250 (UGC 9497) were selected as candidates to emission-line galaxies on Hamburg Quasar Survey objective prism photoplates (Hagen et al. ... The spectrograph SP-124 in the Nasmyth-1 focus of the 6-m telescope with Schmidt-Cassegren camera and Photometrix CCD PM1024 ( m pixel size) are used for these observations. ... Long-slit spectra in the ranges 3700-6100 (for HS 1013+3809 and HS 1442+4250) and 5000-7400 ? HS 1442+4250) are obtained. ...

2. Optimization of spectroscopic observations
... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

3. RCJ0311+0507
... 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"). ...

4. Informational system "Evolution of RG"
The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
