Journal Article
Hartley, K. E., Calia, D. B., Bustos, F. P., Centrone, M., Jenkins, D., Wilson, R. W., & Osborn, J. (2025). Laser guide stars as comparison stars: correcting scintillation noise. Monthly Notices of the Royal Astronomical Society, 539(3), 1955-1963. https://doi.org/10.1093/mnras/staf614

The Earth’s atmosphere severely limits ground-based high precision photometry. Whilst adaptive optics can be used to improve image resolution, intensity fluctuations due to scintillation and atmospheric transparency variations remain. Scintillation n...

Efficient implementation of pseudo open loop control for adaptive optics on Extremely Large Telescopes (2019)
Journal Article
Basden, A., Jenkins, D., Morris, T., Osborn, J., & Townson, M. (2019). Efficient implementation of pseudo open loop control for adaptive optics on Extremely Large Telescopes. Monthly Notices of the Royal Astronomical Society, 486(2), 1774-1780. https://doi.org/10.1093/mnras/stz918

Closed-loop adaptive optics systems which use minimum mean square error wavefront reconstruction require the computation of pseudo open loop wavefront slopes. These techniques incorporate a knowledge of atmospheric statistics which must therefore be...

A many-core CPU prototype of an MCAO and LTAO RTC for ELT-scale instruments (2019)
Journal Article
Jenkins, D. R., Basden, A. G., & Myers, R. M. (2019). A many-core CPU prototype of an MCAO and LTAO RTC for ELT-scale instruments. Monthly Notices of the Royal Astronomical Society, 485(4), 5142-5152. https://doi.org/10.1093/mnras/stz638

We propose a many-core CPU architecture for Extremely Large Telescope (ELT) scale adaptive optics (AO) real-time control (RTC) for the multi-conjugate AO (MCAO) and laser-tomographic AO (LTAO) modes. MCAO and LTAO differ from the more conventional si... Read More about A many-core CPU prototype of an MCAO and LTAO RTC for ELT-scale instruments.

ELT-scale adaptive optics real-time control with the Intel Xeon Phi Many Integrated Core Architecture (2018)
Journal Article

We propose a solution to the increased computational demands of Extremely Large Telescope (ELT) scale adaptive optics (AO) real-time control with the Intel Xeon Phi Knights Landing (KNL) Many Integrated Core (MIC) Architecture. The computational dema... Read More about ELT-scale adaptive optics real-time control with the Intel Xeon Phi Many Integrated Core Architecture.
