We have carried out the first spatially resolved investigation of the multiphase interstellar medium (ISM) at high redshift, using the z = 4.24 strongly lensed submillimetre galaxy H-ATLASJ142413.9+022303 (ID141). We present high-resolution (down to... Read More about A high-resolution investigation of the multiphase ISM in a galaxy during the first two billion years.

Halo concentration strengthens dark matter constraints in galaxy-galaxy strong lensing analyses (2021)
Journal Article
Amorisco, N. C., Nightingale, J., He, Q., Amvrosiadis, A., Cao, X., Cole, S., Etherington, A., Frenk, C. S., Li, R., Massey, R., & Robertson, A. (2022). Halo concentration strengthens dark matter constraints in galaxy-galaxy strong lensing analyses. Monthly Notices of the Royal Astronomical Society, 510, 2464-2479. https://doi.org/10.1093/mnras/stab3527

A defining prediction of the cold dark matter cosmological model is the existence of a very large population of low-mass haloes. This population is absent in models in which the dark matter particle is warm (WDM). These alternatives can, in principle...

An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field: halo masses for submillimetre galaxies (2021)
Journal Article
Stach, S., Smail, I., Amvrosiadis, A., Swinbank, A., Dudzevičiūtė, U., Geach, J., Almaini, O., Birkin, J., Chen, C.-C., Conselice, C., Cooke, E., Coppin, K., Dunlop, J., Farrah, D., Ikarashi, S., Ivison, R., & Wardlow, J.

Monthly Notices of the Royal Astronomical Society, 504(1), https://doi.org/10.1093/mnras/stab714

We present an analysis of the spatial clustering of a large sample of high-resolution, interferometically identified, submillimetre galaxies (SMGs). We measure the projected cross-correlation function of ∼350 SMGs in the UKIDSS Ultra Deep-Survey Fiel...

PyAutoLens: Open-Source Strong Gravitational Lensing (2021)
Journal Article
Nightingale, J., Hayes, R., Kelly, A., Amvrosiadis, A., Etherington, A., He, Q., Li, N., Cao, X., Frawley, J., Cole, S., Enia, A., Frenk, C., Harvey, D., Li, R., Massey, R., Negrello, M., & Robertson, A. (2021). PyAutoLens: Open-Source Strong Gravitational Lensing. The Journal of Open Source Software, 6(58), Article 2825. https://doi.org/10.21105/joss.02825

Strong gravitational lensing, which can make a background source galaxy appears multiple times due to its light rays being deflected by the mass of one or more foreground lens galaxies, provides astronomers with a powerful tool to study dark matter,...
