I. Since the crew of astronomers in this Observational Techniques course already has some experience with "optical telescopes" and a working knowledge of optics and diffraction theory, it's useful to apply that experience to radio telescopes. ... The telescope is a favorite to Australian astronomers for observing the 21cm spectral line of atomic hydrogen. ... The idea is to use the Parkes All-Sky Survey in the 21cm line to estimate some parameters for your favourite galaxy. ...

... The dayside auroral precipitation consist of magnetosheath related boundary layer precipitation, and plasma sheet related BPS/CPS precipitation (extensions of the nightside precipitation regions). ... For example, the much lower fluxes from the LLBL region when compared to the cusp are compensated by the bidirectional electron beams found in the LLBL: the precipitating energy fluxes in the LLBL and the cusp are not that different. ... directly through the cusp and plasma mantle . ...

... We considered our current level of technology compared to that of an average alien civilization. Regardless of any modest value of L chosen?500 years, 5000 years, or longer?their level of technology is vastly advanced compared to ours. Thus, most science fiction gets it right by having advanced alien technology, but gets it wrong by not making them sufficiently advanced. ... What would alien civilizations at a distance of 100 or 1000 lightyears know of us (hypothetically)? ... Education . ...

... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars,   total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...

... Stotskii A. A. Path length fluctuations through the Earth troposphere: turbulent model and data of observations. The spatial and temporal structure functions of path length the Earth troposphere for the whole space and time ranges constructed on the base of turbulence theory are considered. These structure functions include three domains: a power law of 5/3 (three-dimensional turbulence), a power law of 2/3 (two-dimensional turbulence) and saturation. ...

... Line radiative transfer in C 18 O, HCO + , and CS lines is considered in a spherically symmetric chemo-dynamical model of a starless core, evolution of which is driven by the ambipolar diffusion. Theoretical line profiles are compared to observational data on the well-known L1544 core, which is one of possible candidates for collapsing protostellar clouds. ... Comparison between modelled and observed spectra suggests that L1544 has flattened structure and is observed at some inclination. ...

In total, over 7.000 workers and about 500 students from 15 regions of Russia take part in construction of the unique, the most modern and high-tech space-launch complex of the country. ...

Here we compare the optical properties of porous nonspherical particles of two kinds: . ... For each considered value of porosity P, we give first 8 figures on 1 page that show the dependence of the dimesionless extinction (Q ext ) and linear polarization (Q pol ) cross-sections particles on their difraction parameter x v = 2 pi r v / lambda, where r v is the radius of a sphere which volume is equal to that of a nonspherical particle, lambda is the wavelength of incident radiation. ...
