The Quest for Microwave Foreground X
Angelica de Oliveira-Costa, Max Tegmark, R. D. Davies +4
The WMAP team has produced a foreground map that can account for most of the low-frequency Galactic microwave emission in the WMAP maps, tentatively interpreting it as synchrotron…
Inferring the coronal flaring patterns in AGN from reverberation maps
R. Goyder, A. N. Lasenby
The relativistically broadened iron K-alpha line at 6.4 keV observed in the Seyfert 1 galaxy MCG-6-30-15 has provided a probe of the strong-gravity environment near a black hole, i…
Searching for non-Gaussianity in the VSA data
Richard Savage, Richard A. Battye, Pedro Carreira +28
We have tested Very Small Array (VSA) observations of three regions of sky for the presence of non-Gaussianity, using high-order cumulants, Minkowski functionals, a wavelet-based t…
The lack of variability of the iron line in MCG-6-30-15: general relativistic effects
G. Miniutti, A. C. Fabian, R. Goyder +1
The spectrum and variability of the Seyfert galaxy MCG-6-30-15 can be decomposed into two apparently disconnected components: a highly variable power law and an almost constant com…
Closed Universes, de Sitter Space and Inflation
Anthony Lasenby, Chris Doran
We present a new approach to constructing inflationary models in closed universes. Conformal embedding of closed-universe models in a de Sitter background suggests a quantisation c…
Maximum-entropy image reconstruction using wavelets
Klaus Maisinger, M. P. Hobson, A. N. Lasenby
Wavelet functions allow the sparse and efficient representation of a signal at different scales. Recently the application of wavelets to the denoising of maps of cosmic microwave b…
