Model waveform accuracy standards for gravitational wave data analysis

Model waveforms are used in gravitational wave data analysis to detect and then to measure the properties of a source by matching the model waveforms to the signal from a detector. This paper derives accuracy standards for model waveforms which are sufficient to ensure that these data analysis applications are capable of extracting the full scientific content of the data, but without demanding excessive accuracy that would place undue burdens on the model waveform simulation community. These accuracy standards are intended primarily for broadband model waveforms produced by numerical simulations, but the standards are quite general and apply equally to such waveforms produced by analytical or hybrid analytical-numerical methods

“Modern prophets, produce a new bible”: Christianity, Africanness and the poetry of Nontsizi Mgqwetho

In this article I consider how one might approach the apparently singular figure of Nontsizi Mgqwetho, a Xhosa woman who produced an extraordinary series of Christian izibongo in newspapers in the 1920s: through what kind of language, from what critical perspective, might one think and write about her? There have been various attempts to write about Mgqwetho, and there are certain obvious possibilities in terms of approach and methodology, which I explore briefly, but I want to suggest a mode of reading which provides a richer, more engaged and more engaging understanding – one which reads with and through, rather than onto or against, her African Christian articulations.Department of HE and Training approved lis
