Massive post-starburst galaxies at z > 1 are compact proto-spheroids (2017)
Journal Article
Almaini, O., Wild, V., Maltby, D. T., Hartley, W. G., Simpson, C., Hatch, N. A., McLure, R. J., Dunlop, J. S., & Rowlands, K. (2017). Massive post-starburst galaxies at z > 1 are compact proto-spheroids. Monthly Notices of the Royal Astronomical Society, 472(2), 1401-1412. https://doi.org/10.1093/mnras/stx1957

We investigate the relationship between the quenching of star formation and the structural transformation of massive galaxies, using a large sample of photometrically-selected poststarburst galaxies in the UKIDSS UDS field. We find that post-starburs... Read More about Massive post-starburst galaxies at z > 1 are compact proto-spheroids.

Enhancement of AGN in a protocluster at z=1.6 (2017)
Journal Article
Krishnan, C., Hatch, N. A., Almaini, O., Kocevski, D., Cooke, E. A., Hartley, W. G., Hasinger, G., Maltby, D. T., Muldrew, S. I., & Simpson, C. (2017). Enhancement of AGN in a protocluster at z=1.6. Monthly Notices of the Royal Astronomical Society, 470(2), 2170-2178. https://doi.org/10.1093/mnras/stx1315

We investigate the prevalence of AGN in the high-redshift protocluster Cl 0218.3–0510 at z = 1.62. Using imaging from the Chandra X-ray Telescope, we find a large overdensity of AGN in the protocluster; a factor of 23±9 times the field density of AGN...

OMEGA – OSIRIS Mapping of Emission-line Galaxies in A901/2: II. Environmental influence on integrated star formation properties and AGN activity (2017)
Journal Article
Rodríguez del Pino, B., Aragón-Salamanca, A., Chies-Santos, A. L., Weinzirl, T., Bamford, S. P., Gray, M. E., Böhm, A., Wolf, C., & Maltby, D. T. (2017). OMEGA – OSIRIS Mapping of Emission-line Galaxies in A901/2: II. Environmental influence on integrated star formation properties and AGN activity. Monthly Notices of the Royal Astronomical Society, 467(4), 4200-4217. https://doi.org/10.1093/mnras/stx228

We present a study of the star formation and AGN activity for galaxies in CP 15051 the Abell 901/2 multicluster system at z ∼ 0.167 as part of the OSIRIS Mapping of Emission-line Galaxies in A901/2 (OMEGA) survey. Using Tuneable Filter data obtained... Read More about OMEGA – OSIRIS Mapping of Emission-line Galaxies in A901/2: II. Environmental influence on integrated star formation properties and AGN activity.
