nIFTy galaxy cluster simulations – V. Investigation of the cluster infall region
(Oxford University Press, 2016)
We examine the properties of the galaxies and dark matter haloes residing in the cluster
infall region surrounding the simulated cold dark matter galaxy cluster studied by Elahi
et al. at z = 0. The 1.1 × 1015 h−1M ...
A framework for assessing the performance of pulsar search pipelines
(Oxford Unviersity Press, 2016)
In this paper, we present a framework for assessing the effect of non-stationary Gaussian noise and radio frequency interference (RFI) on the signal to noise ratio, the
number of false positives detected per true positive ...
Bringing together knowledge and capabilities: a case study of engineering graduates
(Springer Verlag, 2016)
In contemporary times there is a renewed focus on the purposes of university
education in science or engineering, especially inemerging economycontexts like South Africa
where the massification of higher education is in ...
Identifying multiple periodicities in sparse photon event time series
(Oxford University Press, 2016)
The data considered are event times (e.g. photon arrival times, or the occurrence of sharp
pulses). The source is multiperiodic, or the data could be multiperiodic because several unresolved sources contribute to the time ...
Dark energy homogeneity in general relativity: Are we applying it correctly?
(Springer, 2016)
Thus far, there does not appear to be an agreed (or adequate) definition of
homogeneous dark energy (DE). This paper seeks to define a valid, adequate homogeneity
condition for DE. Firstly, it is shown that as long as ...
On the time delay between ultra-relativistic particles
(Elsevier, 2016)
The time delay between the receptions of ultra-relativistic particles emitted simultaneously is a useful observable for both fundamental physics and cosmology. The expression of the delay when the particles travel through ...
