Boundary effects in a quasi-two-dimensional driven granular fluid (2017)
Journal Article

The effect of a confining boundary on the spatial variations in granular temperature of a driven quasi-2d layer of particles is investigated experimentally. The radial drop in the relative granular temperature ?T/T, exhibits a maximum at intermediate... Read More about Boundary effects in a quasi-two-dimensional driven granular fluid.

Optical detection and spatial modulation of mid-infrared surface plasmon polaritons in a highly doped semiconductor (2017)
Journal Article

Highly doped semiconductors (HDSCs) are promising candidates for plasmonic applications in the mid-infrared (MIR) spectral range. This work examines a recent addition to the HDSC family, the dilute nitride alloy In(AsN). Post-growth hydrogenation of...

Gravity in the quantum lab (2017)
Journal Article

At the beginning of the previous century, Newtonian mechanics was advanced by two new revolutionary theories, Quantum Mechanics (QM) and General Relativity (GR). Both theories have transformed our view of physical phenomena, with QM accurately predic... Read More about Gravity in the quantum lab.

Gravitational mechanisms to self-tune the cosmological constant: obstructions and ways forward (2017)
Journal Article

Gravitational models of self-tuning are those in which vacuum energy has no observable effect on spacetime curvature, even though it is a priori unsuppressed below the cut-off. We complement Weinberg's no go theorem by studying field theoretic comple... Read More about Gravitational mechanisms to self-tune the cosmological constant: obstructions and ways forward.

Phonon spectroscopy with chirped shear and compressive acoustic pulses (2017)
Journal Article

Picosecond duration compressive and shear phonon wave packets injected into (311) GaAs slabs transform after propagation through ?1??mm into chirped acoustic pulses with a frequency increasing in time due to phonon dispersion. By probing the temporal... Read More about Phonon spectroscopy with chirped shear and compressive acoustic pulses.

Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology (2017)
Journal Article

Moment-to-moment reaction time variability on tasks of attention, often quantified by intra-individual response variability (IRV), provides a good indication of the degree to which an individual is vulnerable to lapses in sustained attention. Increa... Read More about Neural circuitry underlying sustained attention in healthy adolescents and in ADHD symptomatology.

Noise switching at a dynamical critical point in a cavity-conductor hybrid (2017)
Journal Article

Coupling a mesoscopic conductor to a microwave cavity can lead to fascinating feedback effects which generate strong correlations between the dynamics of photons and charges. We explore the connection between cavity dynamics and charge transport in... Read More about Noise switching at a dynamical critical point in a cavity-conductor hybrid.

Galaxy Cluster Mass Reconstruction Project: III. The impact of dynamical substructure on cluster mass estimates (2017)
Journal Article

With the advent of wide-field cosmological surveys, we are approaching samples of hundreds of thousands of galaxy clusters. While such large numbers will help reduce statistical uncertainties, the control of systematics in cluster masses is crucial.... Read More about Galaxy Cluster Mass Reconstruction Project: III. The impact of dynamical substructure on cluster mass estimates.

Major merging history in CANDELS. I. Evolution of the incidence of massive galaxy–galaxy pairs from z = 3 to z ∼ 0 (2017)
Journal Article

The rate of major galaxy–galaxy merging is theoretically predicted to steadily increase with redshift during the peak epoch of massive galaxy development (1 ≤ z ≤ 3). We use close-pair statistics to objectively study the incidence of massive galaxies... Read More about Major merging history in CANDELS. I. Evolution of the incidence of massive galaxy–galaxy pairs from z = 3 to z ∼ 0.

Cosmic CARNage I: on the calibration of galaxy formation models (2017)
Journal Article

We present a comparison of nine galaxy formation models, eight semi-analytical, and one halo occupation distribution model, run on the same underlying cold dark matter simulation (cosmological box of comoving width 125h−1 Mpc, with a dark-matter part...

Follow Up of GW170817 and Its Electromagnetic Counterpart by Australian-Led Observing Programmes (2017)
Journal Article

The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era of multi-messenger astronomy. In this paper, we present follow-up obs... Read More about Follow Up of GW170817 and Its Electromagnetic Counterpart by Australian-Led Observing Programmes.

VLT/FORS2 view at z ~ 6: Lyman-α emitter fraction and galaxy physical properties at the edge of the epoch of cosmic reionization (2017)
Journal Article

The fraction of Lyman-α emitters (LAEs) among the galaxy population has been found to increase from z ~ 0 to z ~ 6 and drop dramatically at z> 6. This drop has been interpreted as an effect of an increasingly neutral intergalactic medium (IGM) with i...

SDSS-IV MaNGA: probing the kinematic morphology–density relation of early-type galaxies with MaNGA (2017)
Journal Article

The “kinematic” morphology–density relation for early-type galaxies posits that those galaxies with low angular momentum are preferentially found in the highest-density regions of the universe. We use a large sample of galaxy groups with halo masses... Read More about SDSS-IV MaNGA: probing the kinematic morphology–density relation of early-type galaxies with MaNGA.

Magnetic anisotropy in antiferromagnetic hexagonal MnTe (2017)
Journal Article

Antiferromagnetic hexagonal MnTe is a promising material for spintronic devices relying on the control of antiferromagnetic domain orientations.

Magnetic monopole mass bounds from heavy ion collisions and neutron stars (2017)
Journal Article

Magnetic monopoles, if they exist, would be produced amply in strong magnetic fields and high temperatures via the thermal Schwinger process. Such circumstances arise in heavy-ion collisions and in neutron stars, both of which imply lower bounds on t...

Lattice-Matched Epitaxial Graphene Grown on Boron Nitride (2017)
Journal Article

Lattice-matched graphene on hexagonal boron nitride is expected to lead to the formation of a band-gap but requires the formation of highly strained material and has not hitherto been realised. We demonstrate that aligned, lattice-matched graphene ca... Read More about Lattice-Matched Epitaxial Graphene Grown on Boron Nitride.
