Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...

... We have generated high resolution maps by using standard spherical harmonics expansion for the CMB fluctuations and by extrapolating available full sky maps to predict the Galaxy emission at frequencies and angular scales appropriate to the PLANCK space mission. ... Beam responses are typically not symmetric when they are coupled to a telescope to reach high resolutions, whereas theoretical predictions and standard deconvolution methods generally assume pure symmetric beams. ...

Close binary systems of the RS CVn and Algol type are characterized by a highly variable radio emission, from typical flux densities of a few mJy during low-activity (quiescent) periods, up to 1 Jy during strong flares. The origin of this radio emission is attributed to the gyrosynchrotron mechanism. Several observations of these stars have shown an evolution of the radio spectrum during both the rising and decay phases of flares. ...
