Journal Article
Ferreras, I., Cropper, M., Sharples, R., Bland-Hawthorn, J., Bruzual, G., Charlot, S., …Windhorst, R. (2021). Chronos: A NIR spectroscopic galaxy survey to probe the most fundamental stages of galaxy evolution. Experimental Astronomy, 51(3), https://doi.org/10.1007/s10686-021-09702-2

We propose a dedicated, ultra-deep spectroscopic survey in the near infrared (NIR), that will target a mass-limited sample of galaxies during two of the most fundamental epochs of cosmic evolution: the formation of the first galaxies (at z ≳ 6; cosmi...

2D measurements of plasma electron density using coherence imaging with a pixelated phase mask (2021)
Journal Article
Allcock, J., Silburn, S., Sharples, R., Harrison, J., Conway, N., & Vernimmen, J. (2021). 2D measurements of plasma electron density using coherence imaging with a pixelated phase mask. Review of Scientific Instruments, 92(7), Article 073506. https://doi.org/10.1063/5.0050704

In this paper, the pixelated phase mask (PPM) method of interferometry is applied to coherence imaging (CI)—a passive, narrowband spectral imaging technique for diagnosing the edge and divertor regions of fusion plasma experiments. Compared to previo... Read More about 2D measurements of plasma electron density using coherence imaging with a pixelated phase mask.

The KMOS galaxy evolution survey (KGES): the angular momentum of star-forming galaxies over the last ≍10 Gyr (2021)
Journal Article

The KMOS galaxy evolution survey (KGES): the angular momentum of star-forming galaxies over the last ≍10 Gyr. Monthly Notices of the Royal Astronomical Society, 506(1), 323-342. https://doi.org/10.1093/mnras/stab1692

We present the KMOS Galaxy Evolution Survey (KGES), a K-band Multi-Object Spectrograph (KMOS) study of the H α and [N II] emission from 288 K-band-selected galaxies at 1.2 ≲ z ≲ 1.8, with stellar masses in the range log10(M∗/M⊙)≈9 – 11.5. In this pap... Read More about The KMOS galaxy evolution survey (KGES): the angular momentum of star-forming galaxies over the last ≍10 Gyr.

Development of an 11-channel multi wavelength imaging diagnostic for divertor plasmas in MAST Upgrade (2021)
Journal Article
Feng, X., Calcines, A., Sharples, R., Lipschultz, B., Perek, A., Vijvers, W., …Mumgaard, R. (2021). Development of an 11-channel multi wavelength imaging diagnostic for divertor plasmas in MAST Upgrade. Review of Scientific Instruments, 92(6), Article 063510. https://doi.org/10.1063/5.0043533

Divertor detachment and alternative divertor magnetic geometries are predicted to be promising approaches to handle the power exhaust of future fusion devices. In order to understand the detachment process caused by volumetric losses in alternative d...
