Published: March 2018

We simulate the behaviour of a Higgs-like field in the vicinity of a Schwarzschild black hole using a highly accurate numerical framework. We consider both the limit of the zero-temperature Higgs potential and a toy model for the time-dependent evolution of the potential when immersed in a slowly cooling radiation bath. Through these numerical investigations, we aim to improve our understanding of the non-equilibrium dynamics of a symmetry-breaking field (such as the Higgs) in the vicinity of a compact object such as a black hole. Understanding this dynamics may suggest new approaches for studying properties of scalar fields using black holes as a laboratory.This article is part of the Theo Murphy meeting issue 'Higgs Cosmology'.

We examine nucleosynthesis in the ejecta of black-hole-neutron-star mergers based on the results of long-term neutrino-radiation-magnetohydrodynamics simulations for the first time. We find that the combination of dynamical and postmerger ejecta reproduces a solarlike r-process pattern. Moreover, the enhancement level of actinides is highly sensitive to the distribution of both the electron fraction and the velocity of the dynamical ejecta.

We performed the first simulations of accretion onto the compact objects in the Reissner-Nordström (RN) space-time. The results obtained in general relativity are representative of those for spherically symmetric naked singularities and black holes in a number of modified gravity theories. A possible application of these calculations is to the active galactic nuclei with their powerful jets and outflows.

The Instagram account (@Balance_ton_bar) highlighted the issue of sexual violence in Brussels nightlife sharing testimonials from victim-survivors. Set up in response to reports of drug-facilitated sexual assault at nightlife establishments, the account aimed to raise awareness and hold establishments accountable. This study examines these testimonials to explore how violence was perpetrated-through chemical drugging, alcohol use, isolation, and social power-the socio-emotional consequences for victim-survivors, and their journeys in seeking support.
