We present an analysis of the chemical abundance properties of ≈650 star-forming galaxies at z ≈ 0.6–1.8. Using integral-field observations from the K-band multi-object spectrograph (KMOS), we quantify the [N II]/H α emission-line ratio, a proxy for...

Doppler coherence imaging of scrape-off-layer impurity flows in the HL-2A tokamak (2020)
Journal Article
Long, T., Allcock, J., Nie, L., Sharples, R., Xu, M., Ke, R., …Duan, X. (2020). Doppler coherence imaging of scrape-off-layer impurity flows in the HL-2A tokamak. Review of Scientific Instruments, 91(8), Article 083504. https://doi.org/10.1063/5.0005609

A new Doppler coherence imaging spectroscopy interferometer has been developed on the HL-2A tokamak for the scrape-off-layer impurity flow measurement. Its spatial resolution is estimated to be up to ∼0.8 mm in the horizontal direction and ∼9 mm in t...

KASHz: No evidence for ionised outflows instantaneously suppressing star formation in moderate luminosity AGN at z∼1.4–2.6. Monthly Notices of the Royal Astronomical Society, 492(3), 3194-3216. https://doi.org/10.1093/mnras/staa030

As part of our KMOS AGN Survey at High-redshift (KASHz), we present spatially-resolved VLT/KMOS and VLT/SINFONI spectroscopic data and ALMA 870μm continuum imaging of eight z=1.4–2.6 moderate AGN (⁠L 2−10kev L2−10kev = 1042 − 1045 ergs s−1). We map [... Read More about KASHz: No evidence for ionised outflows instantaneously suppressing star formation in moderate luminosity AGN at z∼1.4–2.6.
