The ultraluminous X-ray source NGC 5643 ULX1: a large stellar mass black hole accreting at super-Eddington rates? (2016)
Journal Article
Pintore, F., Zampieri, L., Sutton, A., Roberts, T., Middleton, M., & Gladstone, J. (2016). The ultraluminous X-ray source NGC 5643 ULX1: a large stellar mass black hole accreting at super-Eddington rates?. Monthly Notices of the Royal Astronomical Society, 459(1), 455-466. https://doi.org/10.1093/mnras/stw669

A sub-set of the brightest ultraluminous X-ray sources (ULXs), with X-ray luminosities well above 1040 erg s−1, typically have energy spectra which can be well described as hard power laws, and short-term variability in excess of ∼10 per cent. This c... Read More about The ultraluminous X-ray source NGC 5643 ULX1: a large stellar mass black hole accreting at super-Eddington rates?.

Distinguishing b-quark and gluon jets with a tagged b hadron (2016)
Journal Article
Gonçalves, D., Krauss, F., & Linten, R. (2016). Distinguishing b-quark and gluon jets with a tagged b hadron. Physical Review D, 93(5), Article 053013. https://doi.org/10.1103/physrevd.93.053013

Based on the knowledge of the QCD radiation pattern, observables to distinguish jets containing one and two b hadrons are discussed. A simple method is used to combine pairs of the most sensitive observables—girth, number of charged tracks and the en... Read More about Distinguishing b-quark and gluon jets with a tagged b hadron.

Closing up on Dark Sectors at colliders: from 14 to 100 TeV (2016)
Journal Article
Harris, P., Khoze, V. V., Spannowsky, M., & Williams, C. (2016). Closing up on Dark Sectors at colliders: from 14 to 100 TeV. Physical Review D, 93(5), Article 054030. https://doi.org/10.1103/physrevd.93.054030

-channel) messenger fields: scalar, pseudoscalar, vector or axial-vector. Our analysis extends and updates the previously available results for the LHC at 8 and 14 TeV to 100 TeV for models with all four messenger types. We revisit and improve the an...

Associated production of a top pair and a Higgs boson beyond NLO (2016)
Journal Article
Broggio, A., Ferroglia, A., Pecjak, B. D., Signer, A., & Yang, L. L. (2016). Associated production of a top pair and a Higgs boson beyond NLO. Journal of High Energy Physics, 2016(3), Article 124. https://doi.org/10.1007/jhep03%282016%29124

We consider soft gluon emission corrections to the production of a top-antitop pair in association with a Higgs boson at hadron colliders. In particular, we present a soft-gluon resummation formula for this production process and gather all elements... Read More about Associated production of a top pair and a Higgs boson beyond NLO.

The EAGLE simulations of galaxy formation: Public release of halo and galaxy catalogues (2016)
Journal Article
McAlpine, S., Helly, J., Schaller, M., Trayford, J., Qu, Y., Furlong, M., …Lemson, G. (2016). The EAGLE simulations of galaxy formation: Public release of halo and galaxy catalogues. Astronomy and computing, 15, 72-89. https://doi.org/10.1016/j.ascom.2016.02.004

We present the public data release of halo and galaxy catalogues extracted from the eagle suite of cosmological hydrodynamical simulations of galaxy formation. These simulations were performed with an enhanced version of the gadget code that includes... Read More about The EAGLE simulations of galaxy formation: Public release of halo and galaxy catalogues.

Collective atomic scattering and motional effects in a dense coherent medium (2016)
Journal Article
Bromley, S., Zhu, B., Bishof, M., Zhang, X., Bothwell, T., Schachenmayer, J., …Ye, J. (2016). Collective atomic scattering and motional effects in a dense coherent medium. Nature Communications, 7, Article 11039. https://doi.org/10.1038/ncomms11039

We investigate collective emission from coherently driven ultracold 88Sr atoms. We perform two sets of experiments using a strong and weak transition that are insensitive and sensitive, respectively, to atomic motion at 1 μK. We observe highly direct...

A tomographic algorithm to determine tip-tilt information from laser guide stars (2016)
Journal Article
Reeves, A., Morris, T., Myers, R., Bharmal, N., & Osborn, J. (2016). A tomographic algorithm to determine tip-tilt information from laser guide stars. Monthly Notices of the Royal Astronomical Society, 459(1), 333-341. https://doi.org/10.1093/mnras/stw622

Laser Guide Stars (LGS) have greatly increased the sky-coverage of Adaptive Optics (AO) systems. Due to the up-link turbulence experienced by LGSs, a Natural Guide Star (NGS) is still required, preventing full sky-coverage. We present a method of obt...

Vertical disc heating in Milky Way-sized galaxies in a cosmological context (2016)
Journal Article
Grand, R., Springel, V., Gómez, F., Marinacci, F., Pakmor, R., Campbell, D., & Jenkins, A. (2016). Vertical disc heating in Milky Way-sized galaxies in a cosmological context. Monthly Notices of the Royal Astronomical Society, 459(1), 199-219. https://doi.org/10.1093/mnras/stw601

Vertically extended, high velocity dispersion stellar distributions appear to be a ubiquitous feature of disc galaxies, and both internal and external mechanisms have been proposed to be the major driver of their formation. However, it is unclear to... Read More about Vertical disc heating in Milky Way-sized galaxies in a cosmological context.

Viscoelastic and elastomeric active matter: Linear instability and nonlinear dynamics (2016)
Journal Article
Hemingway, E., Cates, M., & Fielding, S. (2016). Viscoelastic and elastomeric active matter: Linear instability and nonlinear dynamics. Physical Review E, 93(3), Article 032702. https://doi.org/10.1103/physreve.93.032702

We consider a continuum model of active viscoelastic matter, whereby an active nematic liquid crystal is coupled to a minimal model of polymer dynamics with a viscoelastic relaxation time τC. To explore the resulting interplay between active and poly... Read More about Viscoelastic and elastomeric active matter: Linear instability and nonlinear dynamics.
