Halo ratio from ground based all-sky imaging
The halo ratio (HR) is a quantitative measure characterizing the occurrence of the 22 halo peak associated with cirrus. We propose to obtain it from an approximation to the scattering phase function (SPF) derived from ...
Molecular and atomic gas in dust lane early-type galaxies - I : Low star-formation efficiencies in minor merger remnants
In this work we present IRAM-30m telescope observations of a sample of bulge-dominated galaxies with large dust lanes, which have had a recent minor merger. We find these galaxies are very gas rich, with H2 masses between ...
The Effect of Retro-reflectivity and Reflectance of UK Number Plates on ANPR Performance
The UK police service is one of the biggest users of ANPR technology in the world and over a number of years Police Forces have reported variances in ANPR performance based upon the retro-reflectivity properties of UK ...
The ATLAS(3D) project - I. : A volume-limited sample of 260 nearby early-type galaxies: science goals and selection criteria
The ATLAS3D project is a multiwavelength survey combined with a theoretical modelling effort. The observations span from the radio to the millimetre and optical, and provide multicolour imaging, two-dimensional kinematics ...
