Characterising Complexity in Solar Magnetogram Data using a Wavelet-based Segmentation Method
GALLAGHER, PETER; CONLON, PAUL ANTHONY; MCATEER, ROBERT (2010)The multifractal nature of solar photospheric magnetic structures are studied using the 2D wavelet transform modulus maxima (WTMM) method. This relies on computing partition functions from the wavelet transform skeleton ... -
Coronal Mass Ejection Detection using Wavelets, Curvelets and Ridgelets: Applications for Space Weather Monitoring
GALLAGHER, PETER; MCATEER, ROBERT; BYRNE, JASON (2011)Coronal mass ejections (CMEs) are large-scale eruptions of plasma and magnetic field that can produce adverse space weather at Earth and other locations in the Heliosphere. Due to the intrinsic multiscale nature of features ... -
The kinematics of coronal mass ejections using multiscale methods
GALLAGHER, PETER; BYRNE, JASON; MCATEER, ROBERT (2009)Aims. The diffuse morphology and transient nature of coronal mass ejections (CMEs) make them difficult to identify and track using traditional image processing techniques. We apply multiscale methods to enhance the visibility ... -
QUANTIFYING THE EVOLVING MAGNETIC STRUCTURE OF ACTIVE REGIONS
GALLAGHER, PETER; MCATEER, ROBERT; CONLON, PAUL ANTHONY (2010)The topical and controversial issue of parameterizing the magnetic structure of solar active regions has vital implications in the understanding of how these structures form, evolve, produce solar flares, and decay. This ...
