Journal Article
Gardner, E., & Done, C. (2018). What powers the most relativistic jets? – II. Flat-spectrum radio quasars. Monthly Notices of the Royal Astronomical Society, 473(2), 2639-2654. https://doi.org/10.1093/mnras/stx2516

Flat Spectrum Radio Quasars (FSRQs) are the most powerful relativistic jets seen from supermassive black holes (BHs) accreting via a radiatively efficient thin disc. Their high energy emission is well modelled by highly relativistic electrons in the... Read More about What powers the most relativistic jets? – II. Flat-spectrum radio quasars.

We study the kinematic properties of the Eastern Banded Structure (EBS) and Hydra I overdensity using exquisite proper motions derived from the Sloan Digital Sky Survey (SDSS) and Gaia source catalogue. Main sequence turn-off stars in the vicinity of... Read More about Cresting the wave: proper motions of the Eastern Banded Structure.

Galaxy evolution in protoclusters (2017)
Journal Article

We investigate galaxy evolution in protoclusters using a semi-analytic model applied to the Millennium Simulation, scaled to a Planck cosmology. We show that the model reproduces the observed behaviour of the star formation history (SFH) both in prot... Read More about Galaxy evolution in protoclusters.

Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen–Back regime (2017)

We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S1/2,5P1/2,5P3/25S1/2,5P1/2,5P3/2 and 5D3/25D3/2 terms) in a thermal vapour of 87Rb87Rb atoms. We investigate the 4WM spectra u... Read More about Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen–Back regime.

Local magnetism and spin dynamics of the frustrated honeycomb rhodate Li2RhO3 (2017)
Journal Article

We reportmagnetization, heat capacity, 7Li nuclear magnetic resonance (NMR), and muon-spin rotation (μSR) measurements on the honeycomb 4d5 spin liquid candidate Li2RhO3. The magnetization in small magnetic fields provides evidence of the partial spi... Read More about Local magnetism and spin dynamics of the frustrated honeycomb rhodate Li2RhO3.

The vertical structure of gaseous galaxy discs in cold dark matter haloes (2017)
Journal Article
Benítez-Llambay, A., Navarro, J. F., Frenk, C. S., & Ludlow, A. D. (2018). The vertical structure of gaseous galaxy discs in cold dark matter haloes. Monthly Notices of the Royal Astronomical Society, 473(1), 1019-1037. https://doi.org/10.1093/mnras/stx2420

We study the vertical structure of polytropic centrifugally supported gaseous discs embedded in cold dark matter (CDM) haloes. At fixed radius, R, the shape of the vertical density profile depends weakly on whether the disc is self-gravitating (SG) o...

Can a quantum state over time resemble a quantum state at a single time? (2017)
Journal Article
Horsman, D., Heunen, C., Pusey, M. F., Barrett, J., & Spekkens, R. W. (2017). Can a quantum state over time resemble a quantum state at a single time?. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 473(2205), Article 20170395. https://doi.org/10.1098/rspa.2017.0395

The standard formalism of quantum theory treats space and time in fundamentally different ways. In particular, a composite system at a given time is represented by a joint state, but the formalism does not prescribe a joint state for a composite of s...

Recently acquired WFC3 UV (F275W and F336W) imaging mosaics under the Legacy Extragalactic UV Survey (LEGUS), combined with archival ACS data of M51, are used to study the young star cluster (YSC) population of this interacting system. Our newly extr... Read More about The young star cluster population of M51 with LEGUS – I. A comprehensive study of cluster formation and evolution.

Origins of carbon-enhanced metal-poor stars (2017)

We investigate the nature of carbon-enhanced metal-poor (CEMP) stars in Milky Way (MW) analogues selected from the EAGLE cosmological hydrodynamical simulation.

Thermal winds in stellar mass black hole and neutron star binary systems (2017)
Journal Article

Black hole binaries show equatorial disc winds at high luminosities, which apparently disappear during the spectral transition to the low/hard state. This is also where the radio jet appears, motivating speculation that both wind and jet are driven b... Read More about Thermal winds in stellar mass black hole and neutron star binary systems.
