Although currently poorly constrained, cosmological ultra-large scales are expected to provide formidable tests not only of General Relativity, but also of the content of CDM an…
Using SKAO to Understand the Clustering of Gravitational Wave Sources
Michele Bosi, Sarah Libanore, Nicola Bellomo +4
Coalescing Binary Black Holes (BBHs) trace the Large-Scale Structure (LSS) of the Universe, and their clustering properties can be extracted from Gravitational Wave (GW) data. Next…
Interpretable Neural Marked Statistics for Cosmological Inference
Federico Semenzato, Benjamin D. Wandelt, Michele Liguori +1
Recovering cosmological information beyond the power spectrum is a central goal for upcoming cosmological surveys, since late-time non-Gaussian signal in the matter density cannot…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
Joint 21-cm and CMB Forecasts for Constraining Self-Interacting Massive Neutrinos
Sarah Libanore, Subhajit Ghosh, Ely D. Kovetz +2
Self-interacting neutrinos provide an intriguing extension to the Standard Model, motivated by both particle physics and cosmology. Recent cosmological analyses suggest a bimodal p…
Observed unequal-time power spectrum
Francesco Spezzati, Eleonora Vanzan, Alvise Raccanelli +2
The next generation of galaxy surveys will provide highly precise measurements of galaxy clustering, therefore requiring a corresponding accuracy. Current approaches, which rely on…
Projecting Unequal Time Fields and Correlators of Large Scale Structure
Theodore Steele, Alvise Raccanelli, Zvonimir Vlah
Many large scale structure surveys sort their observations into redshift bins and treat every tracer as being located at the mean redshift of its bin, a treatment which we refer to…
Testing the growth of cosmic structures during the Dark Ages
Elena Vanetti, Eleonora Vanzan, Nicola Bellomo +1
Hydrogen 21-cm Line Intensity Mapping offers the unique opportunity to access the Dark Ages and trace the formation and evolution of the large scale structure of the Universe prior…
Cross-Correlating the Universe: The Gravitational Wave Background and Large-Scale Structure
Federico Semenzato, J. Andrew Casey-Clyde, Chiara M. F. Mingarelli +4
The nature of the gravitational wave background (GWB) is a key question in modern astrophysics and cosmology, with significant implications for understanding the structure and evol…
3D-Radial galaxy correlation function

Tests of cosmological models via measurements of galaxy correlations will require increasing modeling accuracy, given the high precision of measurements promised by forthcoming gal…
Searching for blue in the dark
Jessie de Kruijf, Eleonora Vanzan, Kimberly K. Boddy +2
The primordial power spectrum of curvature perturbations has been well-measured on large scales but remains fairly unconstrained at smaller scales, where significant deviations fro…
The full-sky Spherical Fourier-Bessel power spectrum in general relativity
Federico Semenzato, Daniele Bertacca, Alvise Raccanelli
We present a formalism for analyzing galaxy clustering on the lightcone with the 2-point correlation in the Spherical Fourier-Bessel (SFB) formalism, which is a natural choice to a…
