Journal Article
Smit, R., Swinbank, A., Massey, R., Richard, J., Smail, I., & Kneib, J. (2017). A gravitationally boosted MUSE survey for emission-line galaxies at z ≳ 5 behind the massive cluster RCS 0224. Monthly Notices of the Royal Astronomical Society, 476(3), 3306-3323. https://doi.org/10.1093/mnras/stx245

We present a Very Large Telescope/Multi Unit Spectroscopic Explorer (MUSE) survey of lensed high-redshift galaxies behind the z = 0.77 cluster RCS 0224−0002. We study the detailed internal properties of a highly magnified (μ ∼ 29) z = 4.88 galaxy see...

Revisiting the extremely fast disc wind in a gravitationally lensed quasar APM 08279+5255 (2017)
Journal Article
Hagino, K., Done, C., Odaka, H., Watanabe, S., & Takahashi, T. (2017). Revisiting the extremely fast disc wind in a gravitationally lensed quasar APM 08279+5255. Monthly Notices of the Royal Astronomical Society, 468(2), 1442-1452. https://doi.org/10.1093/mnras/stx559

The gravitationally lensed quasar APM 08279+5255 has the fastest claimed wind from any active galactic nucleus, with velocities of 0.6–0.7c, requiring magnetic acceleration as special relativistic effects limit all radiatively driven winds to v < 0.3...

Cosmic X-ray surveys of active galactic nuclei: The synergy between X-ray and infrared observations (2017)
Journal Article
Alexander, D. (2017). Cosmic X-ray surveys of active galactic nuclei: The synergy between X-ray and infrared observations. Astronomical Notes, 338(2-3), 172-177. https://doi.org/10.1002/asna.201713326

We briefly review the synergy between X-ray and infrared observations for active galactic nuclei (AGNs) detected in cosmic X-ray surveys, primarily with XMM-Newton, Chandra, and NuSTAR. We focus on two complementary aspects of this X-ray–infrared syn... Read More about Cosmic X-ray surveys of active galactic nuclei: The synergy between X-ray and infrared observations.

Complete renormalization of QCD at five loops (2017)
Journal Article
Luthe, T., Maier, A., Marquard, P., & Schröder, Y. (2017). Complete renormalization of QCD at five loops. Journal of High Energy Physics, 2017(3), Article 20. https://doi.org/10.1007/jhep03%282017%29020

We present new analytical five-loop Feynman-gauge results for the anomalous dimensions of ghost field and -vertex, generalizing the known values for SU(3) to a general gauge group. Together with previously published results on the quark mass and -fie... Read More about Complete renormalization of QCD at five loops.

Contactless nonlinear optics mediated by long-range Rydberg interactions (2017)
Journal Article
Busche, H., Huillery, P., Ball, S. W., Ilieva, T., Jones, M. P., & Adams, C. S. (2017). Contactless nonlinear optics mediated by long-range Rydberg interactions. Nature Physics, 13(7), 655-658. https://doi.org/10.1038/nphys4058

In conventional nonlinear optics, linear quantum optics1, 2, and cavity quantum electrodynamics3, 4 to create effective photon–photon interactions photons must have, at one time, interacted with matter inside a common medium. In contrast, in Rydberg... Read More about Contactless nonlinear optics mediated by long-range Rydberg interactions.

Hitomi Constraints on the 3.5 keV Line in the Perseus Galaxy Cluster (2017)
Journal Article
Aharonian, F., Akamatsu, H., Akimoto, F., Allen, S., Angelini, L., Arnaud, K., …Zoghbi, A. (2017). Hitomi Constraints on the 3.5 keV Line in the Perseus Galaxy Cluster. Astrophysical Journal Letters, 837(1), Article L15. https://doi.org/10.3847/2041-8213/aa61fa

High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of various massive systems, such as galaxies and clusters, including the Pe...

Magnetic trapping of SH radicals (2017)
Journal Article
Eardley, J., Warner, N., Deng, L., Carty, D., & Wrede, E. (2017). Magnetic trapping of SH radicals. Physical Chemistry Chemical Physics, 19(12), 8423-8427. https://doi.org/10.1039/c7cp00458c

Magnetic trapping of SH radicals, produced via the photostop technique, has been demonstrated. H2S in a skimmed, supersonic molecular beam was photodissociated at 212.8 nm to produce SH inside a 330 mK deep static magnetic trap. The molecular-beam sp...

Mass Distribution in Galaxy Cluster Cores (2017)
Journal Article
Hogan, M., McNamara, B., Pulido, F., Nulsen, P., Russell, H., Vantyghem, A., …Main, R. (2017). Mass Distribution in Galaxy Cluster Cores. Astrophysical Journal, 837(1), Article 51. https://doi.org/10.3847/1538-4357/aa5f56

Many processes within galaxy clusters, such as those believed to govern the onset of thermally unstable cooling and active galactic nucleus feedback, are dependent upon local dynamical timescales. However, accurate mapping of the mass distribution wi... Read More about Mass Distribution in Galaxy Cluster Cores.

Probing the intra-group medium of a z = 0.28 galaxy group (2017)
Journal Article
Bielby, R., Crighton, N., Fumagalli, M., Morris, S., Stott, J., Tejos, N., & Cantalupo, S. (2017). Probing the intra-group medium of a z = 0.28 galaxy group. Monthly Notices of the Royal Astronomical Society, 468(2), 1373-1386. https://doi.org/10.1093/mnras/stx528

We present new MUSE observations of a galaxy group probed by a background quasar. The quasar sightline passes between multiple z = 0.28 galaxies, whilst showing at the same redshift low-ionized metal line species, including Ca ii, Mg i, Mg ii and Fe ...
