21. Molecular gas
The completion of the 12-mm and 3-mm receiver systems on the Compact Array has secured two new astronomical windows into the southern skies. ... These include investigating the molecular gas reservoirs in and around galaxies in the very distant (high redshift) universe. ... Northern hemisphere millimetre interferometers have already observed molecular gas and dust in a handful of high-redshift radio galaxies, confirming that these objects are still forming the bulk of their stars. ...

23. Introduction
Next: Observational Zoo of Binaries Up: No Title Previous: Contents . In the early 1980s, our understanding of binary star evolution љ based on the pioneer work by Paczynski (1971)[ 150 ], Tutukov and Yungelson (1973)[ 195 ], van den Heuvel and Heise (1972)[ 201 ], allowed us to construct a general evolutionary scenario љ which successfully explained the genesis of well-studied normal stars and offered potential explanation for new X-ray sources discovered in space experiments. ...

29. What is Redshift? (2dF QSO Redshift Survey - 2QZ)
... 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 . ...
