Atmospheric turbulence forecasting with a general circulation model for Cerro Paranal (2018)
Journal Article

In addition to astro-meteorological parameters, such as seeing, coherence time, and isoplanatic angle, the vertical profile of the Earth’s atmospheric turbulence strength and velocity is important for instrument design, performance validation and mon...

The digital mirror Langmuir probe: Field programmable gate array implementation of real-time Langmuir probe biasing (2019)
Journal Article

High bandwidth, high spatial resolution measurements of electron temperature, density, and plasma potential are valuable for resolving turbulence in the boundary plasma of tokamaks. While conventional Langmuir probes can provide such measurements, ei...

Identifying optical turbulence profiles for realistic tomographic error in adaptive optics (2019)
Journal Article

For extremely large telescopes, adaptive optics will be required to correct the Earth’s turbulent atmosphere. The performance of tomographic adaptive optics is strongly dependent on the vertical distribution (profile) of this turbulence. An important...

Simulation and optimisation of an astrophotonic reformatter (2018)
Journal Article

Image slicing is a powerful technique in astronomy. It allows the instrument designer to reduce the slit width of the spectrograph, increasing spectral resolving power whilst retaining throughput. Conventionally this is done using bulk optics, such a... Read More about Simulation and optimisation of an astrophotonic reformatter.

Endothelial TRPV4 channels modulate vascular tone by Ca2+‐induced Ca2+ release at inositol 1,4,5‐trisphosphate receptors (2019)
Journal Article

Background and Purpose: The TRPV4 ion channels are Ca2+ permeable, non‐selective cation channels that mediate large, but highly localized, Ca2+ signals in the endothelium. The mechanisms that permit highly localized Ca2+ changes to evoke cell‐wide ac...

Generating artificial reference images for open loop correlation wavefront sensors (2018)
Journal Article

Shack–Hartmann wavefront sensors for both solar and laser guide star adaptive optics (with elongated spots) need to observe extended objects. Correlation techniques have been successfully employed to measure the wavefront gradient in solar adaptive o...

Optical turbulence profiling with Stereo-SCIDAR for VLT and ELT (2018)
Journal Article

Knowledge of the Earth’s atmospheric optical turbulence is critical for astronomical instrumentation. Not only does it enable performance verification and optimisation of existing systems but it is required for the design of future instruments. As a...

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.

A VLT/MUSE galaxy survey towards QSO Q1410: looking for a WHIM traced by BLAs in inter-cluster filaments† (2018)
Journal Article

Cosmological simulations predict that a significant fraction of the low-z baryon budget resides in large-scale filaments in the form of a diffuse plasma at temperatures T ∼ 105 − 107 K. However, direct observation of this so-called warm-hot intergala... Read More about A VLT/MUSE galaxy survey towards QSO Q1410: looking for a WHIM traced by BLAs in inter-cluster filaments†.

Characterization of the infrared/X-ray subsecond variability for the black hole transient GX 339-4 (2018)
Journal Article

We present a detailed analysis of the X-ray/IR fast variability of the Black-Hole Transient GX 339-4 during its low/hard state in 2008 August. Thanks to simultaneous high time resolution observations made with the VLT and RXTE, we performed the first...

Progress toward divertor detachment on TCV within H-mode operating parameters (2019)
Journal Article

Recent experiments on Tokamak à Configuration Variable have made significant progress toward partial detachment of the outer divertor in neutral beam heated H-mode plasmas in conventional and alternative divertor configurations. The heating power req... Read More about Progress toward divertor detachment on TCV within H-mode operating parameters.

MKID digital readout tuning with deep learning (2018)
Journal Article

Microwave Kinetic Inductance Detector (MKID) devices offer inherent spectral resolution, simultaneous read out of thousands of pixels, and photon-limited sensitivity at optical wavelengths. Before taking observations the readout power and frequency o... Read More about MKID digital readout tuning with deep learning.
