Filling in the quasar redshift gap at z∼5.5. II. A complete survey of luminous quasars in the post-reionization universe (2019)
Journal Article
Yang, J., Wang, F., Fan, X., Wu, X., Bian, F., Bañados, E., …Dye, S. (2019). Filling in the quasar redshift gap at z∼5.5. II. A complete survey of luminous quasars in the post-reionization universe. Astrophysical Journal, 871, doi:10.3847/1538-4357/aaf858

We present the final results from our survey of luminous z ~ 5.5 quasars. This is the first systematic quasar survey focusing on quasars at z ~ 5.5, during the post-reionization epoch. It has been challenging to select quasars at 5.3 < z < 5.7 using... Read More

A magnified view of circumnuclear star formation and feedback around an active galactic nucleus at z = 2.6 (2018)
Journal Article
Geach, J. E., Ivison, R. J., Dye, S., & Oteo, I. (2018). A magnified view of circumnuclear star formation and feedback around an active galactic nucleus at z = 2.6. Astrophysical Journal Letters, 866(1), 1-7. doi:10.3847/2041-8213/aae375

We present Atacama Large Millimeter/submillimeter Array observations of an intrinsically radio-bright (L 1.4 GHz = (1.7 ± 0.1) × 1025 W Hz−1) and infrared luminous (L IR ≈ 1013 L ⊙) galaxy at z = 2.6. The infrared-to-radio luminosity ratio, q = 1.8,... Read More

The causes of the red sequence, the blue cloud, the green valley, and the green mountain (2018)
Journal Article
Eales, S. A., Baes, M., Bourne, N., Bremer, M., Brown, M. J., Clark, C., …Wright, A. (2018). The causes of the red sequence, the blue cloud, the green valley, and the green mountain. Monthly Notices of the Royal Astronomical Society, 481(1), 1183-1194. doi:10.1093/mnras/sty2220

The galaxies found in optical surveys fall in two distinct regions of a diagram of optical colour versus absolute magnitude: the red sequence and the blue cloud, with the green valley in between. We show that the galaxies found in a submillimetre sur... Read More

The new galaxy evolution paradigm revealed by the Herschel surveys (2017)
Journal Article
Eales, S., Smith, D., Bourne, N., Loveday, J., Rowlands, K., van der Werf, P., …Vlahakis, C. (2018). The new galaxy evolution paradigm revealed by the Herschel surveys. Monthly Notices of the Royal Astronomical Society, 473(3), doi:10.1093/mnras/stx2548. ISSN 0035-8711

The Herschel Space Observatory has revealed a very different galaxyscape from that shown by optical surveys which presents a challenge for galaxy-evolution models. The Herschel surveys reveal (1) that there was rapid galaxy evolution in the very rece... Read More

The UKIRT Hemisphere Survey: definition and J-band data release (2017)
Journal Article
Dye, S., Lawrence, A., Read, M., Fan, X., Kerr, T., Varricatt, W., …Tedds, J. (2018). The UKIRT Hemisphere Survey: definition and J-band data release. Monthly Notices of the Royal Astronomical Society, 473(4), doi:10.1093/mnras/stx2622

This paper defines the UK Infra-Red Telescope (UKIRT) Hemisphere Survey (UHS) and release of the remaining ∼12 700 deg2 of J-band survey data products. The UHS will provide continuous J- and K-band coverage in the Northern hemisphere from a declinati... Read More

A multiwavelength exploration of the [C II]/IR ratio in H-ATLAS/GAMA galaxies out to z = 0.2 (2015)
Journal Article
Ibar, E., Lara-Lopez, M., Herrera-Camus, R., Hopwood, R., Bauer, A., Ivison, R., …Valiante, E. (2015). A multiwavelength exploration of the [C II]/IR ratio in H-ATLAS/GAMA galaxies out to z = 0.2. Monthly Notices of the Royal Astronomical Society, 449(3), 2498-2513. doi:10.1093/mnras/stv439

We explore the behaviour of [C ii] λ157.74 μm forbidden fine-structure line observed in a sample of 28 galaxies selected from ∼ 50 deg2 of the Herschel-Astrophysical Terahertz Large Area Survey survey. The sample is restricted to galaxies with flux d... Read More
