James Jackman

I am a PhD student in the Astronomy and Astrophysics group at the University of Warwick. My supervisor is Peter Wheatley. I work as part of the Next Generation Transit Survey (NGTS), currently looking for stellar flares in our dataset. These are explosive magnetic reconnection events which occur on stars ranging from those similar to our Sun to much later spectral types. Once we find these events we can calculate various parameters such as their energy and duration - helping to determine what might happen to exoplanets in their path. Our work on this has been featured in national and international media.

I also work on elements of the NGTS reference catalogue pipeline, in particular the cross-matching of the NGTS source positions with external catalogues such as Gaia, 2MASS and APASS. This allows us to obtain photometry and astrometric information about our objects, which can then be fed into other things (e.g. SED fitting).
