... 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"). ...

... Observation codes for VSOP General Observing Time observations have the form . ... The first letter indicates which AO period the observation was proposed in: the letter `v' indicates the first AO period, and the letter `w' indicates the second and third AO periods. The three digits indicate the proposal number. ... For proposals with more than 26 experiments (see next item), 300 is added to the proposal code for the 27th and subsequent experiments. ...

Next: Data reduction Up: Spectral observations and data Previous: Spectral observations and data . All results presented below have been obtained by observations with the Russian 6m telescope, mainly in the snap-shot mode during 4 runs between December 1998 and February 2000. ... We used a grating with 300 grooves/mm (see log of observations in Table 2 ) and a long slit of 2 40. ... Additional data were obtained with a grating of 650 grooves/mm giving a dispersion of 2.4 ?/pixel. ...

... Down), have conducted astrometric observations of main-belt and near-Earth asteroids using the Observatory's ST-7 CCD camera attached to the Armagh Planetarium's 10-inch Meade Schmidt-Cassegrain telescope. Three main-belt asteroids were observed, namely (304)Olga, (849)Ara and (1146)Biarmia. ... It is believed that these observations were also the first Earth-approaching near-Earth asteroid to be observed with the Faulkes Telescope (see http://star.arm.ac.uk/press/2000PH5.html). ...

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

... Radio emission at around 90 GHz from star-forming galaxies is expected to be strongly dominated by the free-free component due to ionising radiation from massive, short-lived, stars. We present high surface-brightness sensitivity observations at 90 GHz of the nearby star-forming galaxy Messier 66 with resolution of abo
