... 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"). ...

... 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. ...

... December 21, 1997 . ... Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...

The target is a new candidate qLMXB found in the J1655 field of the ChaMPlane survey. ... Use SDSS u,g,r,i,z to take light curves continuously. 3-5min exposures. ... Skyflats: Take twilight skyflats starting shortly after sunset at around 6:00pm. ... Take the first Ha skyflats with adjusted exposure time (remember to turn the tracking on during exposure and off during readout). ... Take the first I filter skyflat with exposure time equal to 1/10 of the last Ha skyflat exposure. ...
