Dusty gas with one fluid in smoothed particle hydrodynamics
(2014-05-21) - Journal article,
In a companion paper we have shown how the equations describing gas and dust as two fluids coupled by a drag term can be re-formulated to describe the system as a single-fluid mixture. Here, we present a numerical ...
Herschel-ATLAS/GAMA : SDSS cross-correlation induced by weak lensing
(2014-08-11) - Journal article,
We report a highly significant (>10σ) spatial correlation between galaxies with S350μm ≥ 30 mJy detected in the equatorial fields of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) with estimated redshifts ...
Radiation thermo-chemical models of protoplanetary discs IV. Modelling CO ro-vibrational emission from Herbig Ae discs
(2013-03) - Journal article,
Context. The carbon monoxide (CO) ro-vibrational emission from discs around Herbig Ae stars and T Tauri stars with strong ultraviolet emissions suggests that fluorescence pumping from the ground X1Σ+ to the electronic A1Π ...
The effects of stellar winds on the magnetospheres and potential habitability of exoplanets
(2014-10) - Journal article,
Context. The principle definition of habitability for exoplanets is whether they can sustain liquid water on their surfaces, i.e. that they orbit within the habitable zone. However, the planet’s magnetosphere should also ...
Strong peak in Tc of Sr2RuO4 under uniaxial pressure
(2017-01-13) - Journal article,
Sr2RuO4 is an unconventional superconductor that has attracted widespread study because of its high purity and the possibility that its superconducting order parameter has odd parity. We study the dependence of its ...
Algebraic order and the Berezinskii-Kosterlitz-Thouless transition in an exciton-polariton gas
(2014-11-24) - Journal article,
We observe quasi-long-range coherence in a two-dimensional condensate of exciton-polaritons. Our measurements confirm that the spatial correlation algebraically decays with a slow power law, whose exponent quantitatively ...
The W43-MM1 mini-starburst ridge, a test for star formation efficiency models
(2014-10) - Journal article,
Context. Star formation efficiency (SFE) theories are currently based on statistical distributions of turbulent cloud structures and a simple model of star formation from cores. They remain poorly tested, especially at the ...
Characterization of the planetary system Kepler-101 with HARPS-N : A hot super-Neptune with an Earth-sized low-mass companion
(2014-12) - Journal article,
We characterize the planetary system Kepler-101 by performing a combined differential evolution Markov chain Monte Carlo analysis of Kepler data and forty radial velocities obtained with the HARPS-N spectrograph. This ...
Morphological, chemical, and electronic changes of the conjugated polymer PTB7 with thermal annealing
(2018-04-27) - Journal article,
There is considerable interest in improving the performance of organic optoelectronic devices through processing techniques. Here, we study the effect of high-temperature annealing on the properties of the semiconducting ...
Photoionising the DIG in the Milky Way : an interesting fine-tuning problem
(2018-07-02) - Conference poster,
