For example, the much lower fluxes from the LLBL region when compared to the cusp are compensated by the bidirectional electron beams found in the LLBL: the precipitating energy fluxes in the LLBL and the cusp are not that different. ... directly through the cusp and plasma mantle . ...

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. ...

... 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"). ...
