The effects of junction interdiffusion and misfit dislocations on the efficiency of highly mismatched heterojunction photovoltaic devices (2016)
Journal Article
Mendis, B., Treharne, R., Lane, D., & Durose, K. (2016). The effects of junction interdiffusion and misfit dislocations on the efficiency of highly mismatched heterojunction photovoltaic devices. Applied Physics Letters, 108(18), Article 183505. https://doi.org/10.1063/1.4948397

A general modelling methodology has been developed to evaluate the effects of chemical interdiffusion and misfit dislocations on the performance of heterojunction solar cells made from highly mismatched materials. Results for the exemplar materials s... Read More about The effects of junction interdiffusion and misfit dislocations on the efficiency of highly mismatched heterojunction photovoltaic devices.

ULX behaviour: The ultraluminous state, winds and interesting anomalies (2016)
Journal Article
Roberts, T., Middleton, M., Sutton, A., Mezcua, M., Walton, D., & Heil, L. (2016). ULX behaviour: The ultraluminous state, winds and interesting anomalies. Astronomical Notes, 377(4-5), 534-540. https://doi.org/10.1002/asna.201612343

Recent evidence – in particular the hard X-ray spectra obtained by NuSTAR, and the large amplitude hard X-ray variability observed when ULXs show soft spectra - reveals that common ultraluminous X-ray source (ULX) behaviour is inconsistent with known...

ALMACAL I: First Dual-band Number Counts from a Deep and Wide ALMA Submillimeter Survey, Free from Cosmic Variance (2016)
Journal Article
Oteo, I., Zwaan, M., Ivison, R., Smail, I., & Biggs, A. (2016). ALMACAL I: First Dual-band Number Counts from a Deep and Wide ALMA Submillimeter Survey, Free from Cosmic Variance. Astrophysical Journal, 822(1), Article 36. https://doi.org/10.3847/0004-637x/822/1/36

We have exploited ALMA calibration observations to carry out a novel, wide, and deep submillimeter (submm) survey, almacal. These calibration data comprise a large number of observations of calibrator fields in a variety of frequency bands and array...

The Spatially Resolved Dynamics of Dusty Starburst Galaxies in a z ~ 0.4 Cluster: Beginning the Transition from Spirals to S0s (2016)
Journal Article
Johnson, H., Harrison, C., Swinbank, A., Bower, R., Smail, I., Koyama, Y., & Geach, J. (2016). The Spatially Resolved Dynamics of Dusty Starburst Galaxies in a z ~ 0.4 Cluster: Beginning the Transition from Spirals to S0s. Monthly Notices of the Royal Astronomical Society, 460(1), 1059-1076. https://doi.org/10.1093/mnras/stw1030

To investigate what drives the reversal of the morphology–density relation at intermediate/high redshift, we present a multiwavelength analysis of 27 dusty starburst galaxies in the massive cluster Cl 0024+17 at z = 0.4. We combine Hα dynamical maps... Read More about The Spatially Resolved Dynamics of Dusty Starburst Galaxies in a z ~ 0.4 Cluster: Beginning the Transition from Spirals to S0s.

Magnetization dynamics and frustration in the multiferroic double perovskite Lu2MnCoO6 (2016)
Journal Article

We investigate the magnetic ordering and the magnetization dynamics (from kHz to THz time scales) of the double perovskite Lu2MnCoO6 using elastic neutron diffraction, muon spin relaxation, and micro-Hall magnetization measurements. This compound is... Read More about Magnetization dynamics and frustration in the multiferroic double perovskite Lu2MnCoO6.

The origin of compact galaxies with anomalously high black hole masses (2016)
Journal Article
Barber, C., Schaye, J., Bower, R., Crain, R., Schaller, M., & Theuns, T. (2016). The origin of compact galaxies with anomalously high black hole masses. Monthly Notices of the Royal Astronomical Society, 460(1), 1147-1161. https://doi.org/10.1093/mnras/stw1018

Observations of local galaxies harbouring supermassive black holes (BH) of anomalously high mass, MBH, relative to their stellar mass, M*, appear to be at odds with simple models of the co-evolution between galaxies and their central BHs. We study th... Read More about The origin of compact galaxies with anomalously high black hole masses.

Direct measurement of excited-state dipole matrix elements using electromagnetically induced transparency in the hyperfine Paschen-Back regime (2016)
Journal Article

Applying large magnetic fields to gain access to the hyperfine Paschen-Back regime can isolate three-level systems in a hot alkali metal vapors, thereby simplifying usually complex atom-light interactions. We use this method to make the first direct...

Modelling the number density of Hα emitters for future spectroscopic near-IR space missions (2016)
Journal Article

Context. The future space missions Euclid and WFIRST-AFTA will use the Hα emission line to measure the redshifts of tens of millions of galaxies. The Hα luminosity function at z> 0.7 is one of the major sources of uncertainty in forecasting cosmologi...
