Journal Article
Teodoro, L. F. A., Kegerreis, J. A., Estrada, P. R., Ćuk, M., Eke, V. R., Cuzzi, J. N., Massey, R. J., & Sandnes, T. D. (2023). A Recent Impact Origin of Saturn’s Rings and Mid-sized Moons. Astrophysical Journal, 955(2), Article 137. https://doi.org/10.3847/1538-4357/acf4ed

We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn's remarkably young rings. Such an event could have been triggered a few hundred million years ago by resonant instabilities in a previous sat... Read More about A Recent Impact Origin of Saturn’s Rings and Mid-sized Moons.

(N)NLO+NLL’ accurate predictions for plain and groomed 1-jettiness in neutral current DIS (2023)
Journal Article

The possibility to reanalyse data taken by the HERA experiments offers the chance to study modern QCD jet and event-shape observables in deep-inelastic scattering. To address this, we compute resummed and matched predictions for the 1-jettiness distr... Read More about (N)NLO+NLL’ accurate predictions for plain and groomed 1-jettiness in neutral current DIS.

Biocompatible Ti3Au–Ag/Cu thin film coatings with enhanced mechanical and antimicrobial functionality (2023)

Background
Biofilm formation on medical device surfaces is a persistent problem that shelters bacteria and encourages infections and implant rejection. One promising approach to tackle this problem is to coat the medical device with an antimicrobial...

The outer dusty edge of accretion disks in active galactic nuclei (2023)
Journal Article
Landt, H. (2023). The outer dusty edge of accretion disks in active galactic nuclei. Frontiers in Astronomy and Space Sciences, 10, 1256088. https://doi.org/10.3389/fspas.2023.1256088

Recent models for the inner structure of active galactic nuclei (AGN) aim at connecting the outer region of the accretion disk with the broad-line region and dusty torus through a radiatively accelerated, dusty outflow. Such an outflow not only requi... Read More about The outer dusty edge of accretion disks in active galactic nuclei.

We introduce a high-level graphical framework for designing and analysing quantum error correcting codes, centred on what we term the coherent parity check (CPC). The graphical formulation is based on the diagrammatic tools of the ZX-calculus of quan... Read More about Graphical structures for design and verification of quantum error correction.

In this article we combine a recently proposed method for factorisation-aware matrix element surrogates with an unbiased unweighting algorithm. We show that employing a sophisticated neural network emulation of QCD multijet matrix elements based on d...
