Lightning activity on a tidally locked terrestrial exoplanet in storm-resolving simulations for a range of surface pressures
Denis E. Sergeev, James W. McDermott, Lottie Woods +3
Cloudy atmospheres produce electric discharges, including lightning. Lightning, in turn, provides sufficient energy to break down air molecules into reactive species and thereby af…

Impacts of UV Radiation from an AGN on Planetary Atmospheres and Consequences for Galactic Habitability
Kendall I. Sippy, Jake K. Eager-Nash, Ryan C. Hickox +2
We present a study of the effects of ultraviolet (UV) emission from active galactic nuclei (AGN) on the atmospheric composition of planets and potential impact on life. It is expec…

Biosignatures from pre-oxygen photosynthesising life on TRAPPIST-1e
Jake K. Eager-Nash, Stuart J. Daines, James W. McDermott +13
In order to assess observational evidence for potential atmospheric biosignatures on exoplanets, it will be essential to test whether spectral fingerprints from multiple gases can…
