The Robotic Multiobject Focal Plane System of the Dark Energy Spectroscopic Instrument (DESI). Astronomical Journal, 165(1), Article 9. https://doi.org/10.3847/1538-3881/ac9ab1

A system of 5,020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically re-target their optical fibers every 10 - 20 minutes, each to a precision of several microns, with...

Doppler coherence imaging spectroscopy (CIS) has been installed on J-TEXT tokamak to provide a wealth of information for carbon impurity ions (CIII). To obtain the local emissivity and flow from the line-integrated information measured by the camera,...

The HR image slicer for GNIRS at Gemini North: optical design and performance (2022)
Presentation / Conference Contribution
Calcines Rosario, A., Dubbeldam, C. M., Sharples, R., Bourgenot, C., Diaz, R., & Stephens, A. W. (2022, December). The HR image slicer for GNIRS at Gemini North: optical design and performance. Presented at Ground-based and Airborne Instrumentation for Astronomy IX

GNIRS (Gemini Near-InfraRed Spectrograph) is a multi-function spectrograph at Gemini North telescope offering four observational modes in the spectral range of 0.8 to 5.4 µm. It provides 2-pixel spectral resolutions from 1,200 up to 18,0000 and has s... Read More about The HR image slicer for GNIRS at Gemini North: optical design and performance.

The resolved chemical abundance properties within the interstellar medium of star-forming galaxies at z≈ 1.5 (2022)
Journal Article
Gillman, S., Puglisi, A., Dudzevičiūtė, U., Swinbank, A., Tiley, A., Harrison, C., Molina, J., Sharples, R., Bower, R., Cirasuolo, M., Ibar, E., & Obreschkow, D. (2022). The resolved chemical abundance properties within the interstellar medium of star-forming galaxies at z≈ 1.5. Monthly Notices of the Royal Astronomical Society, 512(3), 3480-3499. https://doi.org/10.1093/mnras/stac580

We exploit the unprecedented depth of integral field data from the KMOS Ultra-deep Rotational Velocity Survey (KURVS) to analyse the strong (Hα) and forbidden ([NII], [SII]) emission line ratios in 22 main-sequence galaxies at z ≈ 1.5. Using the [NII... Read More about The resolved chemical abundance properties within the interstellar medium of star-forming galaxies at z≈ 1.5.
