# Proto-Neutron Star Convection and the Neutrino-Driven Wind: Implications for the r-Process

2 Feb 2023

We also find that both entropy production after shock formation and the acceleration of the wind due to stresses produced by the waves prior to shock formation impact the structure and nucleosynthesis of these waves.

# Evidence for suppression of structure growth in the concordance cosmological model

2 Feb 2023

The combination of $f\sigma_8$ and Planck measurements prefers an even higher growth index of $\gamma=0. 639^{+0. 024}_{-0. 025}$, corresponding to a 4. 2$\sigma$-tension with the concordance model.

# CzSL: A new learning paradigm for astronomical image classification with citizen science

1 Feb 2023

However, existing approaches have neglected the fact that, apart from the data labelled by amateurs, (limited) expert knowledge of the problem is also available along with vast amounts of unlabelled data that have not yet been exploited within a unified learning framework.

# High-redshift supermassive black hole mergers in simulations with dynamical friction modelling

1 Feb 2023

The black hole populations in Astrid include black holes down to 10$^{4. 5}$ M$_\odot$, and remain broadly consistent with the TNG simulations at scales > 10$^6$ M$_\odot$ (the seed mass used in TNG).

# Minkowski Functionals in $SO(3)$ for the spin-2 CMB polarisation field

30 Jan 2023

In this paper, we extend the application of MFs to CMB polarisation data by introducing a new formalism, where we lift the spin $2$ polarisation field to a scalar function in a higher dimensional manifold: the group of rotations of the sphere, $SO(3)$.
