The 2dF QSO Redshift Survey — I. The optical luminosity function of quasi-stellar objects
We present a determination of the optical luminosity function of quasi-stellar objects (QSOs) and its cosmological evolution with redshift for a sample of over 6000 QSOs identified primarily from theExpand

  • 3 July 1975
For the Korteweg-de Vries equation ut+ux+uux+uxxx=0, existence, uniqueness, regularity and continuous dependence results are established for both the pure initial-value problem (posed on -∞<x<∞) andExpand
The dwarf LSB galaxy population of the Virgo cluster - I. The faint-end slope of the luminosity function
The widely varying dwarf galaxy counts in different environments provide a strong challenge to standard hierarchical clustering models. The luminosity function is not universal, but seems to beExpand
Combining multileaf fields to modulate fluence distributions.
Optimize distributions that conform the dose to irregularly shaped target volumes that wrap around critical structures are possible using superimposed multileaf fields. Expand
Fourier transform Raman spectroscopic studies of human bone
We have concluded preliminary investigations concerning the composition of human cortical bone tissue, and of a number of samples of synthetic hydroxyapatite, using Fourier transform Raman (FT-Raman)Expand
We have used deep GALEX observations at the infall region of the Coma cluster to measure the faintest UV luminosity functions (LFs) presented for a rich galaxy cluster thus far. The Coma UV LFs areExpand
Supercritical fluids in separation science--the dreams, the reality and the future.

  • 24 September 1999
The rise and fall of supercritical fluids represents a lesson in the way analysts approach new techniques and how the authors might view other new separation developments at the end of this millennium. Expand
Determination of sulphur compounds in beer using headspace solid-phase microextraction and gas chromatographic analysis with pulsed flame photometric detection.

  • 3 March 2000
Increased sensitivity was obtained over previous methods, such as dynamic headspace followed by conventional flame photometric detection or sulphur chemiluminescent detection, with high sulphur selectivity. Expand
Nonlinear effects upon waves near caustics
According to linear theory the wave intensity of a slowly varying wave train becomes particularly large near caustics. In this paper it is shown how the waves are modified when the wave intensity isExpand
On the local dark matter density
Context. In 2012, we applied a three-dimensional formulation to kinematic measurements of the Galactic thick disk and derived a surprisingly low dark matter density at the solar position. This resultExpand
