From peculiar morphologies to Hubble-type spirals: the relation between galaxy dynamics and morphology in star-forming galaxies at z ∼ 1.5. Monthly Notices of the Royal Astronomical Society, 492(1), 1492-1512. https://doi.org/10.1093/mnras/stz3576

We present an analysis of the gas dynamics of star–forming galaxies at z ∼ 1.5 using data from the KMOS Galaxy Evolution Survey (KGES). We quantify the morphology of the galaxies using HSTCANDELS imaging parametrically and non-parametrically. We comb...

The digital mirror Langmuir probe: Field programmable gate array implementation of real-time Langmuir probe biasing (2019)
Journal Article
Vincent, C., McCarthy, W., Golfinopoulos, T., LaBombard, B., Sharples, R., Lovell, J., …Kuang, A. (2019). The digital mirror Langmuir probe: Field programmable gate array implementation of real-time Langmuir probe biasing. Review of Scientific Instruments, 90(8), Article 083504. https://doi.org/10.1063/1.5109834

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...

Overview of new MAST physics in anticipation of first results from MAST Upgrade (2019)
Journal Article

The mega amp spherical tokamak (MAST) was a low aspect ratio device (R/a  =  0.85/0.65 ~ 1.3) with similar poloidal cross-section to other medium-size tokamaks. The physics programme concentrates on addressing key physics issues for the operation of... Read More about Overview of new MAST physics in anticipation of first results from MAST Upgrade.

The energetics of starburst-driven outflows at z ∼ 1 from KMOS (2019)
Journal Article

We present an analysis of the gas outflow energetics from KMOS observations of 529 main-sequence star-forming galaxies at z 1 using broad, underlying Hα and forbid- den lines of [Nii] and [Sii]. Based on the stacked spectra for a sample with median s... Read More about The energetics of starburst-driven outflows at z ∼ 1 from KMOS.

The Dynamics and Distribution of Angular Momentum in HiZELS Star – Forming Galaxies at z = 0.8 – 3.3 (2019)
Journal Article

The Dynamics and Distribution of Angular Momentum in HiZELS Star – Forming Galaxies at z = 0.8 – 3.3. Monthly Notices of the Royal Astronomical Society, 486(1), 175-194. https://doi.org/10.1093/mnras/stz765

We present adaptive optics assisted integral field spectroscopy of 34 star–forming galaxies at z = 0.8–3.3 selected from the HiZELS narrow-band survey. We measure the kinematics of the ionised interstellar medium on ∼1 kpc scales, and show that the g...

Monthly Notices of the Royal Astronomical Society, 485(4), 5700-5714. https://doi.org/10.1093/mnras/stz750

We present stellar specific angular momentum j* measurements of two z ∼ 1.5 galaxies in the KGES sample and 12 DYNAMO z ∼ 0.1 analogues of high-redshift galaxies. We combine natural seeing integral field spectroscopic data to trace line emission out... Read More about Angular momentum of z ∼ 1.5 galaxies and their local analogues with adaptive optics.

The Shapes of the Rotation Curves of Star-forming Galaxies Over the Last ≈ 10 Gyr (2019)
Journal Article

We analyse maps of the spatially-resolved nebular emission of ≈1500 star-forming galaxies at z ≈ 0.6–2.2 from deep KMOS and MUSE observations to measure the average shape of their rotation curves. We use these to test claims for declining rotation cu... Read More about The Shapes of the Rotation Curves of Star-forming Galaxies Over the Last ≈ 10 Gyr.
