I was a PhD student in the Astronomy and Astrophysics group at the University of Warwick, but am now a postdoc at Arizona State University. An all purpose webpage for my work, that should have updated information, can be found here: https://jackmanjames26.github.io/ . Failing that, my ORCID ID and ASU email is provided on this page.

My supervisor during my time at Warwick was Peter Wheatley. I worked 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 worked 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).

Press Releases

• Explosion on Jupiter-sized star ten times more powerful than ever seen on our Sun - on our detection of the first white-light flare seen from an L2.5 dwarf, a star around the size of Jupiter.

• A baby star's fiery tantrum - on our detection of a giant stellar flare exhibiting QPPs from a pre-main sequence star. This release was picked up by Forbes, the Daily Mail and New Scientist (among others).
