Ok dan ...
Je stuurt op 1 oktober vorig jaar aan alle betrokkenen een brief dat je geen enkele verantwoordelijkheid meer kunt dragen voor de inmiddels ontstane situatie van de gezondheid. Wordt dat door vrijwel alle berokkenen voortdurend verder genegeerd. En krijg je aan het eind de rekening.
Oja ... En als je niet akkoord gaat dan ...

Resurrecting Gravitational Vector Modes and their Magnetogenesis
We revisit the presence of primordial gravitational vector modes (V-modes) and their sourcing of primordial magnetic fields (PMF), i.e. magnetogenesis. As the adiabatic vector mode generically decays with expansion, we consider exotic initial conditions which circumvent this issue and lead to observational imprints. The first initial condition is an isocurvature mode between photons and neutrinos vorticities, and the second one is a non-trivial initial condition on the neutrino octupole. Both t…

The Monte Carlo Computational Summit -- October 25 & 26, 2023 -- Notre Dame, Indiana, USA
The Monte Carlo Computational Summit was held on the campus of the University of Notre Dame in South Bend, Indiana, USA on 25--26 October 2023. The goals of the summit were to discuss algorithmic and software alterations required for successfully porting respective code bases to exascale-class computing hardware, compare software engineering techniques used by various code teams, and consider the adoption of industry-standard benchmark problems to better facilitate code-to-code performance comp…

X-ray polarization observations of NGC 2110 with IXPE
X-ray polarimetric observations from the Imaging X-ray Polarimeter Explorer (IXPE) is an excellent tool for probing the geometry and dynamics of X-ray emitting corona in active galactic nuclei (AGN). This work aims to investigate the geometry of the X-ray corona in the Seyfert 2 AGN, NGC 2110, using its first polarimetric observation with IXPE, conducted over a net exposure of 554 ks beginning on October 16, 2024. We performed a model-independent analysis of the 2-8 keV IXPE polarimetric observ…

Enhanced nuclear Schiff and electric dipole moments in nuclei with an octupole deformation
Deformed nuclei exhibit enhanced moments that violate time-reversal invariance ($T$) and parity ($P$). This paper focuses on the enhanced nuclear electric dipole moment (EDM) and Schiff moment present in nuclei with octupole deformation (pear-shaped nuclei). These moments, which are proportional to the octupole deformation, have a collective nature and are large in the intrinsic frame that rotates with the nucleus. However, in a state with definite angular momentum and parity, $T$ and $P$ conse…

The $α$-particle condensation in diluted $^{16}\text{O}$ at finite temperature
We investigate the effect of temperature on $α$-particle clustering in the diluted nucleus $^{16}\text{O}$ using the multi-constrained finite-temperature relativistic Hartree-Bogoliubov model with the DD-ME2 interaction. At a critical density the nucleus undergoes a Mott-like transition from a homogeneous to a localised configuration characterised by $α$-particle clustering and the emergence of a finite non-axial octupole deformation. We study the interplay between the onset of localisation u…
