... Magnetic fields, subatomic particles, etc., traveling in different directions fill the universe. Do they deflect or otherwise affect one another? If so, isnт??t the information we get from them distorted? ... Neutrino astronomy, which is still in its infancy, is attractive because neutrinos interact so weakly with matter that few of these distorting effects occur.

... 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"). ...

... We have generated high resolution maps by using standard spherical harmonics expansion for the CMB fluctuations and by extrapolating available full sky maps to predict the Galaxy emission at frequencies and angular scales appropriate to the PLANCK space mission. ... Beam responses are typically not symmetric when they are coupled to a telescope to reach high resolutions, whereas theoretical predictions and standard deconvolution methods generally assume pure symmetric beams. ...

... Observations of precipitating (Jp) and trapped (Jt) energetic (> 30 keV) particle fluxes at the ionospheric altitudes within the auroral oval region has revealed the existence of a sharp boundary separating the poleward zone of isotropic precipitation (Jp = Jt) from the equatorward zone of weak loss cone filling (Jp << Jt) at all local times (Sergeev and Malkov, 1988). ... boundaries for higher energy particles are located at lower latitudes than boundaries for lower energy particles . ...
