Costless correction of chain based nested sampling parameter estimation in gravitational wave data and beyond
Metha Prathaban, Will Handley
Nested sampling parameter estimation differs from evidence estimation, in that it incurs an additional source of uncertainty. This uncertainty affects estimates of parameter means…
Simulation-Based Inference of the sky-averaged 21-cm signal from CD-EoR with REACH
Anchal Saxena, P. Daniel Meerburg, Christoph Weniger +2
The redshifted 21-cm signal from the Cosmic Dawn and Epoch of Reionization carries invaluable information about the cosmology and astrophysics of the early Universe. Analyzing data…
On the spatial distribution of the Large-Scale structure: An Unsupervised search for Parity Violation
Samuel Hewson, Will J. Handley, Christopher G. Lester
We use machine learning methods to search for parity violations in the Large-Scale Structure (LSS) of the Universe, motivated by recent claims of chirality detection using the 4-Po…
Extracting cosmological information from the abundance of galaxy clusters with simulation-based inference
Ãñigo Zubeldia, Boris Bolliet, Anthony Challinor +1
The abundance of galaxy clusters as a function of mass and redshift is a well-established and powerful cosmological probe. Cosmological analyses based on galaxy cluster number coun…
