Diamond machining of a single shot ellipsoidal focusing plasma mirror (2016)
Presentation / Conference Contribution
Bourgenot, C., Crosby, D., & Robertson, D. (2016). Diamond machining of a single shot ellipsoidal focusing plasma mirror. In J. Kovacicinova (Ed.), Optics and Measurement International Conference 2016. https://doi.org/10.1117/12.2257414

Plasma mirrors have become an important tool in high power laser physics due to their ability to suppress laser pre-pulses and amplified spontaneous emission allowing a cleaner and sharper rising edge pulse to be focused onto a target. A PMMA ellipso... Read More about Diamond machining of a single shot ellipsoidal focusing plasma mirror.

The origin of scatter in the stellar mass-halo mass relation of central galaxies in the EAGLE simulation (2016)
Journal Article
Matthee, J., Schaye, J., Crain, R., Schaller, M., Bower, R., & Theuns, T. (2017). The origin of scatter in the stellar mass-halo mass relation of central galaxies in the EAGLE simulation. Monthly Notices of the Royal Astronomical Society, 465(2), 2381-2396. https://doi.org/10.1093/mnras/stw2884

We use the hydrodynamical EAGLE simulation to study the magnitude and origin of the scatter in the stellar mass–halo mass relation for central galaxies. We separate cause and effect by correlating stellar masses in the baryonic simulation with halo p...

Dark matter and leptogenesis linked by classical scale invariance (2016)
Journal Article
Khoze, V. V., & Plascencia, A. D. (2016). Dark matter and leptogenesis linked by classical scale invariance. Journal of High Energy Physics, 2016(11), Article 025. https://doi.org/10.1007/jhep11%282016%29025

In this work we study a classically scale invariant extension of the Standard Model that can explain simultaneously dark matter and the baryon asymmetry in the universe. In our set-up we introduce a dark sector, namely a non-Abelian SU(2) hidden sect... Read More about Dark matter and leptogenesis linked by classical scale invariance.

Terahertz (THz) near-field imaging is a flourishing discipline, with applications from fundamental studies of beam propagation to the characterization of metamaterials, and waveguides. Beating the diffraction limit typically involves rastering struct... Read More about Real-Time Near-Field Terahertz Imaging with Atomic Optical Fluorescence.

Context. Accretion of gas from the intergalactic medium is required to fuel star formation in galaxies. We have recently suggested that this process can be studied using host galaxies of gamma-ray bursts (GRBs). Aims. Our aim is to test this possibil...
