Standard cosmology predicts inevitable signals that should be observable as global or all-sky signals. These include the additive distortions to the Cosmic Microwave Background (CMB) spectrum from photons emitted over the Epoch of Recombination. Another is the monopole signal from the redshifted 21-cm signal from hydrogen over the dark-ages, cosmic dawn, and epoch of reionization when the...

Warped galactic discs are common, yet their detection remains challenging, as the outskirts of galaxies are typically faint. Advances in deep imaging surveys improve the detectability of such features, while machine learning enables efficient analysis of large datasets. Using the Pan-STARRS EGIPS catalogue, we develop a deep learning framework by finetuning the Zoobot convNext-nano model on...

Random fields arise in many areas of science, from materials and biology to climate and cosmology. While traditional statistics describe their local properties, topology reveals their global structure. We develop a statistical framework for Betti numbers and the Euler characteristic of excursion sets of smooth random fields by expressing them in terms of random topological components. This...
