The late-time linear Integrated Sachs-Wolfe (ISW) effect directly probes the dynamics of cosmic acceleration and the nature of dark energy. Detecting these weak, secondary temperature anisotropy signals of the CMB requires accurate theoretical predictions of their amplitude across cosmological models. By extending the pyGenISW package, previously limited to $\Lambda$CDM, we aim to generate...

Utilizing a Graph Convolutional Neural Network (GCNN) called DeepSphere as the masked portion of a Masked Auto-regressive Flow (MAF), joint posteriors for Omega-Matter and Sigma-8 can be inferred from density maps and ISW maps derived from the first Gower Street simulation suite.

The Large-Scale Structure (LSS) of the Universe is organised into clusters of galaxies connected by a network of filaments and underdense cosmic voids, which occupy most of the cosmic volume. This LSS can influence the formation and evolution of galaxies and affect their physical properties. However, there is currently no consensus on how to parametrise a galaxy location with respect to...

Dwarf galaxies have low gravitational potential, low metallicity and are vulnerable to effects like shockwaves from supernovae. Star formation is expected to be inefficient in these systems, but that is not the case. I present my kinematical analysis of DDO 43, an isolated irregular dwarf in the Local Universe. I used VLA archival data of the HI content of DDO 43 to describe the local motions...
