Microwave Hotspots: The Oldest Structures Known . ... Credit Copyright: DMR , COBE , NASA Explanation: These spots are the oldest, most distant structures known. They are seen on the above two images of the microwave sky, north and south of our galaxy's equator, based on four-year's worth of data from NASA's COsmic Background Explorer (COBE) satellite (1989-1993). The spots represent temperature variations in the early universe . ... U. Based on Astronomy Picture Of the Day ...

Magnetic field measurements onboard the INTERBALL AURORAL spacecraft. Magnetic field measurements onboard the INTERBALL-2 (Auroral Probe) is carried out by the IMAP-3 instrument. ... The IMAP-3 instrument is designed to measure three components of the DC magnetic field in two ranges: +/- 6800 nT with resolution 1 nT and +/- 68000 nT with resolution 10 nT. ... We cannot calculate now By and Bz components separately due to absence of the spacecraft attitude data. ...

... International Journal of Bifurcations and Chaos , 1998, vol. ... Impulsive synchronization of chaotic dynamic systems has some important applications to chaotic secure communication and chaotic spread-spectrum communication systems. In this paper we present some experimental results on impulsive synchronization between two Chua's circuits. ... The robustness of impulsive synchronization with respect to variations in the frequency and the width of impulses is studied. ...

... the radiative transfer equation (RTE) for the randomly-irregular magnetized plasma has been derived on the base of general grounds of the multiple scattering theory . ... Solutions of several absolute tasks of the scattering theory have been obtained (on the optical depth of the ionospheric plasma layer, on the value of radio wave anomalous attenuation, on anomalous refraction, on the backscattered signal intensity for the source being placed within a plasma layer). ...

Large-scale structure of cold gas . ... Under the data of the catalogue of profiles of HI line absorption, obtained on the radiotelescope RATAN-600 together with outcomes of other authors, large-scale structure of cold interstellar gas is found in the spiral arms of Galaxy. In general these structures are parallel to the axes of a spiral arms. Their diameter in a transversal direction is 100 pc, and there are 4-5 such structures on a line of sight inside the arm. ...

... Research . ... The aim of this project is to study the nearest spiral galaxies in the nearby Sculptor Group in neutral hydrogen with the ATCA to search for high-velocity clouds (HVCs) and extra-planar gas in their environment. ... The Sculptor Group is the nearest galaxy group. ... Therefore, we have mapped a large area of almost $2^{\circ} \times 2^{\circ}$ around the two nearest large Sculptor Group galaxies, NGC 55 and NGC 300, with the ATCA in mosaicking mode. ...

... Study of Mg-Fe-silicate glasses of variable composition. ... With the new data, the astrophysical discussion started in Paper I was continued and focussed on the comparison of the olivine glass data with IRAS LRS spectra of O-rich circumstellar envelopes around Mira stars. ... The new olivine glasses point to the interesting consequence that the temperature for silicate dust grains at the inner edge of circumstellar envelopes must be considerably higher than the values often given in the literature....
