. Top: A map of the hydrogen emission from DLA2222-0946. The mapped region, which covers only a portion of the galaxy, is about 5,000 parsecs (or 16,300 light-years) across. The position of the background quasar is marked by a "Q". Bottom: The corresponding map of the movement of the gas in the galaxy. Red means moving away from us; blue is moving towards us. R.

... OXIDIZED AND HYDRATED SILICATES ON M- AND S- ASTEROIDS: SPECTRAL INDICATIONS. ... In particular, it was shown that a considerable fraction (ab. 35%) of the mainbelt M-type asteroids have absorption bands at 3 µm [3, 6] diagnostic of water of hydration. At the same time it was found that the visible-range reflectance spectra of some M- and Sasteroids include absorption features characterizing presence of oxidized silicates [4, 5]. ... The reflectance spectra of 161 Athor (Fig. 1), 497 Iva (Fig. ...

... A non-standard approach to the interpretation of patrol green-line corona observations is presented The brightness distributions in the years 1964-1986 (cycles 20-21) combined into half-year interval: and three latitudinal zones, were analysed using the statistical method of principal components. has been determined that the variation of brightness distribution with cycle phase and latitude zom may be described by the so-called model of evolving distribution. ...

... During all period of our investigations Dr. N.Sumzina from the Institute of Applied Astronomy of RAS had prepared the Numbered Minor Planet positions from MPC Database for our processing with kind permission of the Director of Minor Planet Center Prof. Braian Marsden. ... Our extensive processing of the MPC data allows us to conclude that CCD observations of the Numbered and Unnumbered Minor Planets have the errors, sometimes very crude. ...

LIFR MI 2 P, Laboratoire International Franco-Russe de Math matiques et Interaction avec l'Informatique et la Physique Th orique is, as its name indicates, a French-Russian mathematics research lab that focuses on fundamental mathematics and its interaction with computer science and theoretical physics.

The aim of this section of the course is to enable you to use simple computer programs to solve a variety of common astronomical tasks. ... I have (somewhat arbitrarily) decided to use Python for this course, because it seems to be gaining popularity fast for astronomical data handling, and because some of you will have encountered it at the ATNF course. ... We've put Python (plus all relevant libraries) on the Stromlo Linux computers moron and maggot. ... Now log in to moron (or maggot). ...

Three day radio-astronomical forecast of the proton activity of the Sun: The figure shows multiwave radio emission scans - graphs of the distribution of intensity I and circular polarization V across the solar disk, obtained at RATAN-600. ... According to this criterion, for a proton flare to arise, the flux of radio emission must be sufficiently high at short wavelengths (blue color scans) and should increase with time compared to the general intensity. ...
