The 2dF QSO Redshift Survey (2QZ) . ... Before jumping into all the finer details of teh survey, a brief non-astronomer's guide to redshift surveys is available. ... The primary scientific aims of the QSO survey are: (1) to obtain the primordial fluctuation power spectrum out to COBE scales, (2) to determine the rate of QSO clustering evolution in the non-linear and linear regimes and hence obtain new limits on the value of and the bias parameter, (3) to apply a powerful geometric method to measure . ...

The aim of this assignment is to teach you how to carry out a very common programming task: reading in a bunch of data from a text file, doing something with it then writing the results out again. ... The goal of the assignment is to write a computer program which will select this sample for you. You will pick the micro-quasars to observe from a rather large catalogue, which can be found here: The catalogue is an ASCII (text) file - you can inspect it with a normal text editor. ...

... For us to see them from such great distances, quasars must be producing enormous energy -- they are about 1000 times brighter than an average galaxy! ... One of their choices for the energy source of quasars was a black hole. ... On the one hand, it may seem difficult to think that mere friction between bits of matter could account for the energy of a quasar, but, on the other hand, gravity is unimaginably strong near a black hole. ...

... We present composite spectra of red and blue sub-samples of the PHFS quasars, and tabulate their emission line properties. The median H and [O III ] emission line equivalent widths of the red quasar sub-sample are a factor of ten weaker than those of the blue quasar sub-sample. ... Both the colours and the emission line equivalent widths of the red quasars can be explained by the addition of a featureless red synchrotron continuum component to an otherwise normal blue quasar spectrum. ...
