Dr Iain Hannah

I am a Senior Lecturer, and former Royal Society University Research Fellow, and my research is focused on the physical processes behind the emission we observe in solar flares (or explosive bursts) in the Sun’s atmosphere. I study this primarily through multi-wavelength observations combined with theory and numerical simulations.

I am particularly interested in small active region flares (microflares and smaller) and also quiet sun emission. I have studied these with the solar X-ray telescope RHESSI, STIX on Solar Orbiter, and with the astrophysics X-ray telescope NuSTAR probing the emission from these weak events. My overview of these solar NuSTAR observations is available on GitHub Pages.

My DEM code demreg is available on GitHub, and works with any optically thin temperature sensitive data in EUV or X-ray, though the code examples show specific examples with solar EUV data from SDO/AIA. The original papers for this approach are Hannah & Kontar (2012) and Hannah & Kontar (2013).
