On the connection between the metal-enriched intergalactic medium and galaxies: an O VI–galaxy cross-correlation study at z < 1 (2016)
Journal Article
Finn, C., Morris, S., Tejos, N., Crighton, N., Perry, R., Fumagalli, M., …Bartle, S. (2016). On the connection between the metal-enriched intergalactic medium and galaxies: an O VI–galaxy cross-correlation study at z < 1. Monthly Notices of the Royal Astronomical Society, 460(1), 590-616. https://doi.org/10.1093/mnras/stw918

We present new results on the auto- and cross-correlation functions of galaxies and O VI absorbers in a ∼18 Gpc3 comoving volume at z < 1. We use a sample of 51 296 galaxies and 140 O VI absorbers in the column density range 13 ≲ log N ≲ 15 to measur...

Forming supermassive black hole seeds under the influence of a nearby anisotropic multifrequency source (2016)
Journal Article
Regan, J., Johansson, P., & Wise, J. (2016). Forming supermassive black hole seeds under the influence of a nearby anisotropic multifrequency source. Monthly Notices of the Royal Astronomical Society, 459(3), 3377-3394. https://doi.org/10.1093/mnras/stw899

The photodissociation of H2 by a nearby anisotropic source of radiation is seen as a critical component in creating an environment in which a direct collapse black hole may form. Employing radiative transfer we model the effect of multifrequency (0.7... Read More about Forming supermassive black hole seeds under the influence of a nearby anisotropic multifrequency source.

Constraints on the identity of the dark matter from strong gravitational lenses (2016)
Journal Article
Li, R., Frenk, C., Cole, S., Gao, L., Bose, S., & Hellwing, W. (2016). Constraints on the identity of the dark matter from strong gravitational lenses. Monthly Notices of the Royal Astronomical Society, 460(1), 363-372. https://doi.org/10.1093/mnras/stw939

The cold dark matter (CDM) cosmological model unambiguously predicts that a large number of haloes should survive as subhaloes when they are accreted into a larger halo. The CDM model would be ruled out if such substructures were shown not to exist.... Read More about Constraints on the identity of the dark matter from strong gravitational lenses.

Probing theories of gravity with phase space-inferred potentials of galaxy clusters (2016)
Journal Article
Stark, A., Miller, C., Kern, N., Gifford, D., Zhao, G., Li, B., …Nichol, R. (2016). Probing theories of gravity with phase space-inferred potentials of galaxy clusters. Physical Review D, 93(8), Article 084036. https://doi.org/10.1103/physrevd.93.084036

Modified theories of gravity provide us with a unique opportunity to generate innovative tests of gravity. In Chameleon f(R) gravity, the gravitational potential differs from the weak-field limit of general relativity (GR) in a mass dependent way. We...

Can we distinguish early dark energy from a cosmological constant? (2016)
Journal Article
Shi, D., & Baugh, C. (2016). Can we distinguish early dark energy from a cosmological constant?. Monthly Notices of the Royal Astronomical Society, 459(4), 3540-3550. https://doi.org/10.1093/mnras/stw882

Early dark energy (EDE) models are a class of quintessence dark energy with a dynamically evolving scalar field which display a small but non-negligible amount of dark energy at the epoch of matter-radiation equality. Compared with a cosmological con... Read More about Can we distinguish early dark energy from a cosmological constant?.

Z-Boson Production in Association with a Jet at Next-To-Next-To-Leading Order in Perturbative QCD (2016)
Journal Article

We present the first complete calculation of Z-boson production in association with a jet in hadronic collisions through next-to-next-to-leading order in perturbative QCD. Our computation uses the recently proposed N-jettiness subtraction scheme to r... Read More about Z-Boson Production in Association with a Jet at Next-To-Next-To-Leading Order in Perturbative QCD.

We report the results of a muon-spin relaxation (μSR) investigation of La2−xSrxCoO4, an antiferromagnetic insulating series which has been shown to support charge ordered and magnetic stripe phases and an hourglass magnetic excitation spectrum. We pr... Read More about Magnetic phase diagram of La2-xSrxCoO 4 revised using muon-spin relaxation.

A versatile dual-species Zeeman slower for caesium and ytterbium (2016)

In a recent paper, Tye and Wong (TW) have argued that sphaleron-induced transitions in high-energy proton-proton collisions should be enhanced compared to previous calculations, based on a construction of a Bloch wave function in the periodic sphaler...
