Baryogenesis via leptonic CP-violating phase transition (2018)
Journal Article
Pascoli, S., Turner, J., & Zhou, Y. (2018). Baryogenesis via leptonic CP-violating phase transition. Physics Letters B, 780, 313-318. https://doi.org/10.1016/j.physletb.2018.03.011

We propose a new mechanism to generate a lepton asymmetry based on the vacuum CP-violating phase transition (CPPT). This approach differs from classical thermal leptogenesis as a specific seesaw model, and its UV completion, need not be specified. Th...

The X-ray Ribs Within the Cocoon Shock of Cygnus A (2018)
Journal Article
Duffy, R., Worrall, D., Birkinshaw, M., Nulsen, P., Wise, M., de Vries, M., …Laing, R. (2018). The X-ray Ribs Within the Cocoon Shock of Cygnus A. Monthly Notices of the Royal Astronomical Society, 476(4), 4848-4860. https://doi.org/10.1093/mnras/sty549

We use new and archival Chandra observations of Cygnus A, totalling ∼1.9 Ms, to investigate the distribution and temperature structure of gas lying within the projected extent of the cocoon shock and exhibiting a rib-like structure. We confirm that t... Read More about The X-ray Ribs Within the Cocoon Shock of Cygnus A.

Giant galaxy growing from recycled gas: ALMA maps the circumgalactic molecular medium of the Spiderweb in [C i] (2018)
Journal Article
Emonts, B., Lehnert, M., Dannerbauer, H., De Breuck, C., Villar-Martín, M., Miley, G., …Norris, R. (2018). Giant galaxy growing from recycled gas: ALMA maps the circumgalactic molecular medium of the Spiderweb in [C i]. Monthly Notices of the Royal Astronomical Society: Letters, 477(1), L60-L65. https://doi.org/10.1093/mnrasl/sly034

The circumgalactic medium (CGM) of the massive Spiderweb Galaxy, a conglomerate of merging proto-cluster galaxies at z = 2.2, forms an enriched interface where feedback and recycling act on accreted gas. This is shown by observations of [CI], CO(1-0)... Read More about Giant galaxy growing from recycled gas: ALMA maps the circumgalactic molecular medium of the Spiderweb in [C i].

First Look at Two-Loop Five-Gluon Scattering in QCD (2018)
Journal Article
Badger, S., Brønnum-Hansen, C., Hartanto, H. B., & Peraro, T. (2018). First Look at Two-Loop Five-Gluon Scattering in QCD. Physical Review Letters, 120(9), Article 092001. https://doi.org/10.1103/physrevlett.120.092001

We compute the leading-color contributions to five-gluon scattering at two loops in massless QCD. The integrands of all independent helicity amplitudes are evaluated using d -dimensional generalized unitarity cuts and finite field reconstruction tech...

We present results on the structural properties of massive passive galaxies in three clusters at 1.39 < z < 1.61 from the KMOS Cluster Survey. We measure light-weighted and mass-weighted sizes from optical and near-infrared Hubble Space Telescope ima...

Static and Fluctuating Magnetic Moments in the Ferroelectric Metal LiOsO3 (2018)
Presentation / Conference Contribution

In Proceedings of the 14th International Conference on Muon Spin Rotation, Relaxation and Resonance (μSR2017). https://doi.org/10.7566/jpscp.21.011013

LiOsO3 is the first example of a new class of material called a ferroelectric metal. We performed zero-field and longitudinal-field μSR, along with a combination of electronic structure and dipole field calculations, to determine the magneticground s...

A Study of Two Dwarf Irregular Galaxies with Asymmetrical Star Formation Distributions (2018)
Journal Article

Two dwarf irregular galaxies, DDO 187 and NGC 3738, exhibit a striking pattern of star formation: intense star formation is taking place in a large region occupying roughly half of the inner part of the optical galaxy. We use data on the H i distribu... Read More about A Study of Two Dwarf Irregular Galaxies with Asymmetrical Star Formation Distributions.

The innate origin of radial and vertical gradients in a simulated galaxy disc (2018)
Journal Article

We examine the origin of radial and vertical gradients in the age/metallicity of the stellar component of a galaxy disc formed in the APOSTLE cosmological hydrodynamical simulations. Some of these gradients resemble those in the Milky Way, where they... Read More about The innate origin of radial and vertical gradients in a simulated galaxy disc.

Structural principles that enable oligomeric small heat-shock protein paralogs to evolve distinct functions (2018)
Journal Article

Structural principles that enable oligomeric small heat-shock protein paralogs to evolve distinct functions. Science, 359(6378), 930-935. https://doi.org/10.1126/science.aam7229

Oligomeric proteins assemble with exceptional selectivity, even in the presence of closely related proteins, to perform their cellular roles. We show that most proteins related by gene duplication of an oligomeric ancestor have evolved to avoid heter...
