A local Fock-exchange potential in Kohn–Sham equations (2016)
Journal Article
Hollins, T., Clark, S., Refson, K., & Gidopoulos, N. (2017). A local Fock-exchange potential in Kohn–Sham equations. Journal of Physics: Condensed Matter, 29(4), Article 04LT01. https://doi.org/10.1088/1361-648x/29/4/04lt01

We derive and employ a local potential to represent the Fock exchange operator in electronic single-particle equations. This local Fock-exchange (LFX) potential is very similar to the exact exchange (EXX) potential in density functional theory (DFT)....

Journal Article
Vantyghem, A., McNamara, B., Russell, H., Hogan, M., Edge, A., Nulsen, P., …Voit, G. (2016). Molecular gas along a bright Hα filament in 2A 0335+096 revealed by Alma. Astrophysical Journal, 832(2), Article 148. https://doi.org/10.3847/0004-637x/832/2/148

We present ALMA CO(1–0) and CO(3–2) observations of the brightest cluster galaxy (BCG) in the 2A 0335+096 galaxy cluster (z = 0.0346). The total molecular gas mass of 1.13 ± 0.15 × 109 M ⊙ is divided into two components: a nuclear region and a 7 kpc...

Ruling out the light weakly interacting massive particle explanation of the Galactic 511 keV line (2016)
Journal Article
Wilkinson, R., Vincent, A., Boehm, C., & McCabe, C. (2016). Ruling out the light weakly interacting massive particle explanation of the Galactic 511 keV line. Physical Review D, 94(10), Article 103525. https://doi.org/10.1103/physrevd.94.103525

Over the past few decades, an anomalous 511 keV gamma-ray line has been observed from the center of the Milky Way. Dark matter (DM) in the form of light (≲10  MeV) weakly interacting massive particles (WIMPs) annihilating into electron-positron pairs...

Hiding in plain sight – recovering clusters of galaxies with the strongest AGN in their cores (2016)
Journal Article
Green, T., Edge, A., Ebeling, H., Burgett, W., Draper, P., Kaiser, N., …Waters, C. (2017). Hiding in plain sight – recovering clusters of galaxies with the strongest AGN in their cores. Monthly Notices of the Royal Astronomical Society, 465(4), 4872-4885. https://doi.org/10.1093/mnras/stw3059

A key challenge in understanding the feedback mechanism of active galactic nucleus (AGN) in Brightest Cluster Galaxies (BCGs) is the inherent rarity of catching an AGN during its strong outburst phase. This is exacerbated by the ambiguity of differen... Read More about Hiding in plain sight – recovering clusters of galaxies with the strongest AGN in their cores.

Hunting for eclipses: high-speed observations of cataclysmic variables (2016)
Journal Article
Hardy, L., McAllister, M., Dhillon, V., Littlefair, S., Bours, M., Breedt, E., …Woudt, P. (2017). Hunting for eclipses: high-speed observations of cataclysmic variables. Monthly Notices of the Royal Astronomical Society, 465(4), 4968-4984. https://doi.org/10.1093/mnras/stw3051

We present new time-resolved photometry of 74 cataclysmic variables (CVs), 47 of which are eclipsing. Thirteen of these eclipsing systems are newly discovered. For all 47 eclipsing systems, we show high cadence (1–20 s) light curves obtained with the... Read More about Hunting for eclipses: high-speed observations of cataclysmic variables.

Study of hard double-parton scattering in four-jet events in pp collisions at sqrt{s}=7 TeV with the ATLAS experiment (2016)
Journal Article
collaboration, A. (2016). Study of hard double-parton scattering in four-jet events in pp collisions at sqrt{s}=7 TeV with the ATLAS experiment. Journal of High Energy Physics, 2016(11), Article 110. https://doi.org/10.1007/jhep11%282016%29110

Inclusive four-jet events produced in proton-proton collisions at a centre-of-mass energy of s√=7s=7 TeV are analysed for the presence of hard double-parton scattering using data corresponding to an integrated luminosity of 37.3 pb−1, collected with...

The exclusive J/ψ process at the LHC tamed to probe the low x gluon (2016)
Journal Article
Jones, S., Martin, A., Ryskin, M., & Teubner, T. (2016). The exclusive J/ψ process at the LHC tamed to probe the low x gluon. The European Physical Journal C, 76(11), Article 633. https://doi.org/10.1140/epjc/s10052-016-4493-y

The perturbative QCD expansion for J/ψ photoproduction appears to be unstable: the NLO correction is large (and of opposite sign) to the LO contribution. Moreover, the predictions are very sensitive to the choice of factorisation and renormalisation... Read More about The exclusive J/ψ process at the LHC tamed to probe the low x gluon.

Subhalo abundance matching in f(R) gravity (2016)
Journal Article
He, J., Li, B., & Baugh, C. M. (2016). Subhalo abundance matching in f(R) gravity. Physical Review Letters, 117(22), Article 221101. https://doi.org/10.1103/physrevlett.117.221101

Using the liminality N-body simulations of Shi et al., we present the first predictions for galaxy clustering in f(R) gravity using subhalo abundance matching. We find that, for a given galaxy density, even for an f(R) model with fR0=−10−6, for which... Read More about Subhalo abundance matching in f(R) gravity.

Cu2ZnSnS4 (CZTS) is a promising material for the absorber layer in sustainable thin film photovoltaic cells, but its best efficiencies are currently limited by low open-circuit voltages, thought to be due to defects such as disorder between the coppe...
