PublicationGalactic wind X-ray heating of the intergalactic medium during the Epoch of Reionization
The diffuse soft X-ray emissivity from galactic winds is computed during the Epoch of Reionization (EoR). We consider two analytic models, a pressure-driven...

PublicationGauss-Seidel and Successive Overrelaxation Methods for Radiative Transfer with Partial Frequency Redistribution
The linearly polarized solar limb spectrum that is produced by scattering processes contains a wealth of information on the physical conditions and magnetic...

PublicationHeight Variation of the Vector Magnetic Field in Solar Spicules
Proving the magnetic configuration of solar spicules has hitherto been difficult due to the lack of spatial resolution and image stability during off-limb...

PublicationHerschel-ATLAS: The dust energy balance in the edge-on spiral galaxy UGC 4754
We use Herschel PACS and SPIRE observations of the edge-on spiral galaxy UGC 4754, taken as part of the H-ATLAS SDP observations, to investigate the dust energy...

PublicationHubble constant and nuclear equation of state from kilonova spectro-photometric light curves
The merger of two compact objects of which at least one is a neutron star is signalled by transient electromagnetic emission in a kilonova (KN). This event is...

TalkIAU G5 Talk: Winds of Magnetic Massive Stars
Massive stars (at least eight times as massive as the Sun) possess strong stellar winds driven by radiation. With the advent of the so called MiMeS...

PublicationImpact of surface dynamo magnetic fields on the solar abundance of the CNO elements
Most studies of the solar metallicity, based on abundance determinations of the CNO elements, ignore the fact that the quiet solar photosphere is significantly...
