The Riemann xi-function is an entire function of order one and its zeroes coincide with non-trivial zeroes of the Riemann zeta-function which lie in the critical strip. The Riemann hypothesis asserts that all zeroes of the Riemann xi-function lie on the critical line. ... Moreover, if the Riemann hypothesis is fulfilled, then all zeroes of derivatives of the Riemann xi-function lie on the critical line. ...

... On the base of laboratory simulations (on rotating shallow water) of the formation of spiral arms in galactic gaseous disks, the existence of giant anticyclones in them was predicted. Numerical simulations shown that the vortex structures arise on a linear stage of spiral arms formation simultaneously with the latter. ... Thus second giants structures, after spiral arms, in spiral galactic disks are discovered. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
