Harmonic analysis of cosmic microwave background data II: from ring-sets to the sky
Anthony D. Challinor, Daniel J. Mortlock, Floor van Leeuwen +4
Despite the fact that the physics of the cosmic microwave background anisotropies is most naturally expressed in Fourier space, pixelised maps are almost always used in the analysi…
Harmonic analysis of cosmic microwave background data I: ring reductions and point-source catalogue
Floor van Leeuwen, Anthony D. Challinor, Daniel J. Mortlock +7
We present a harmonic model for the data analysis of an all-sky cosmic microwave background survey, such as Planck, where the survey is obtained through ring-scans of the sky. In t…
Gravitational lensing in modified Newtonian dynamics
Daniel J. Mortlock, Edwin L. Turner
Modified Newtonian dynamics (MOND) is an alternative theory of gravity that aims to explain large-scale dynamics without recourse to any form of dark matter. However the theory is…
Empirical constraints on alternative gravity theories from gravitational lensing
Daniel J. Mortlock, Edwin L. Turner
If it is hypothesised that there is no dark matter then some alternative gravitational theory must take the place of general relativity (GR) on the largest scales. Dynamical measur…
Using the 6dF galaxy redshift survey to detect gravitationally-lensed quasars
Daniel J. Mortlock, Michael J. Drinkwater
It is possible to detect gravitationally-lensed quasars spectroscopically if the spectra obtained during galaxy surveys are searched for the presence of quasar emission lines. The…
