Carbon capture and storage is a transition technology from a past and present fuelled by coal, oil and gas and a planned future dominated by renewable energy sources. The technology involves the capture of carbon dioxide emissions from fossil fuel po... Read More about Passive, continuous monitoring of carbon dioxide geostorage using muon tomography.

Gamma-ray emission from high Galactic latitude globular clusters (2018)
Journal Article
Lloyd, S. J., Chadwick, P. M., & Brown, A. M. (2018). Gamma-ray emission from high Galactic latitude globular clusters. Monthly Notices of the Royal Astronomical Society, 480(4), 4782-4796. https://doi.org/10.1093/mnras/sty2150

We analyse 8 years of PASS 8 Fermi-LAT data, in the 60 MeV - 300 GeV energy range, from 30 high Galactic latitude globular clusters. Six of these globular clusters are detected with a TS > 25, with NGC 6254 being detected as gamma-ray bright for the...

Understanding the γ-ray emission from the globular cluster 47 Tuc: Evidence for dark matter? (2018)
Journal Article
Brown, A. M., Lacroix, T., Lloyd, S., Bœhm, C., & Chadwick, P. (2018). Understanding the γ-ray emission from the globular cluster 47 Tuc: Evidence for dark matter?. Physical Review D, 98(4), Article 041301(R). https://doi.org/10.1103/physrevd.98.041301

47 Tuc was the first globular cluster observed to be γ -ray bright, with the γ rays being attributed to a population of unresolved millisecond pulsars (MSPs). Recent kinematic data combined with detailed simulations appear to be consistent with the p...

Characterisation and testing of CHEC-M—A camera prototype for the small-sized telescopes of the Cherenkov telescope array (2018)
Journal Article
Zorn, J., White, R., Watson, J., Armstrong, T., Balzer, A., Barcelo, M., …Zink, A. (2018). Characterisation and testing of CHEC-M—A camera prototype for the small-sized telescopes of the Cherenkov telescope array. Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 904, 44-63. https://doi.org/10.1016/j.nima.2018.06.078

The Compact High Energy Camera (CHEC) is a camera design for the Small-Sized Telescopes (SSTs; 4 m diameter mirror) of the Cherenkov Telescope Array (CTA). The SSTs are focused on very-high-energy -ray detection via atmospheric Cherenkov light detect...

Artificial guide stars for adaptive optics using unmanned aerial vehicles (2018)
Journal Article
Basden, A., Brown, A. M., Chadwick, P., Clark, P., & Massey, R. (2018). Artificial guide stars for adaptive optics using unmanned aerial vehicles. Monthly Notices of the Royal Astronomical Society, 477(2), 2209-2219. https://doi.org/10.1093/mnras/sty790

Astronomical adaptive optics systems are used to increase effective telescope resolution. However, they cannot be used to observe the whole sky since one or more natural guide stars of sufficient brightness must be found within the telescope field of...
