Direct power spectral density estimation from structure functions without Fourier transforms
Mark A. Bishop, Sean Oughton, Tulasi N. Parashar +1
Second-order structure functions and power spectral densities are popular tools in the study of statistical properties across scales, particularly for the analysis of turbulent flo…

Constraining solar wind transport model parameters using Bayesian analysis
Mark Bishop, Sean Ougthon, Tulasi Parashar +1
We apply nested-sampling (NS) Bayesian analysis [AshtonEA22] to a model for the transport of MHD-scale solar wind fluctuations. The dual objectives are to obtain improved constrain…

Power spectrum estimation methods on intracluster medium surface brightness fluctuations
Mark Bishop, Yvette Perrott, Tulasi Parashar +1
Accurate estimation of galaxy cluster masses is a central problem in cosmology. Turbulence is believed to introduce significant deviations from the hydrostatic mass estimates. Esti…
