    Notes: [Auszug] In 1947, Waldmeier2 discovered a companion line at X 5445, which he later3 attributed to the transition 2pi spa_,. t in Ca XV. Edlen had pointed out earlier4 that a companion line ought to appear in the visible spectrum, and its discovery supported his original identification. Shklovsky5 showed, ...

    Notes: [Auszug] A mechanism is proposed to explain how cosmic rays and fast electrons in non-thermal radio sources originate. The theory develops from Fermi's suggestion that charged particles gain energy through successive encounters with moving magnetic fields. Considerations of the geometry of cosmic ...

    Notes: [Auszug] THE observation by Penzias and Wilson1 of an isotropic microwave background, later confirmed by Roll and Wilkinson2, has received two conflicting interpretations. Dicke, Peebles, Roll and Wilkinson3 postulate a universe of the type considered by Gamow4, in which the energy density of radiation ...

    Notes: [Auszug] It can be shown that the density of radiation in a uniform and uniformly expanding universe of zero spatial curvature is given in the grey-body approximation (absorption coefficient independent of frequency) by the formula E0 =f - \^L]jL j T(^)J(1) where E0 represents the mean energy density of ...
