... 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"). ...

Next: Setting Up Your Account Up: ATCA Bin Mode Observations Previous: Pulsar bin-mode observations . We now mention a few bin-mode specific tasks. Pulse profiles - PSRPLT: Task psrplt produces a pulse profile (amplitude against bin number). It can also produce a greyscale with axes of bin number and frequency and the greyscale intensity being pulsar amplitude. De-dispersion, rebinning and timing correction - PSRFIX: Task psrfix performs three related functions. ...

... 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. ...

... 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). ...

... 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 about 9 arcsec (corresponding to a physical scale of about 500 pc) and analyse these observations in combination with archival lower frequency radio and mid-infrared measurements. ...

Pulkovo NEO Page . ... NEA Accuracy Estimation . ... The estimation of accuracy of the current CCD observations of asteroids and comets is constantly performed at Pulkovo Observatory. ... The (O-C) values, so called "Observed" minus "Calculated" positions, characterize numerically the observations of any observatory, both professional and amateur, during a short period (one or several close nights). ... So the (O-C) values for these objects nearly entirely define the errors of observations. ...
