... 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 . ...

I was born on April 12, 1958, in Moscow, USSR, and I have a Russian nationality. I graduated the Lomonosov Moscow State University in 1981, obtained there my Ph.D.degree in 1984 (the topic of the dissertation: "Stellar populations and evolution of galaxies") and a degree of Doctor of Physical-Mathematical Sciences in 1994 (the dissertation "Stellar population of galactic nuclei"). Since 1984 I hold a permanent position at the Sternberg Astronomical Institute (Moscow). ...
