Euclid preparation. CIV. Impact of galaxy intrinsic alignment modelling choices on Euclid 3x2pt cosmology
Euclid Collaboration, D. Navarro-Gironés, I. Tutusaus +274
The Euclid galaxy survey will provide unprecedented constraints on cosmology, but achieving unbiased results will require an optimal characterisation and mitigation of systematic e…
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…
Comparing cosmic shear nulling methods for Stage-IV surveys
Naomi Clare Robertson, Alex Hall
We present an analysis comparing nulling strategies for reducing the impact of baryon feedback on cosmic shear measurements. We consider three different approaches which aim to `nu…
Shot noise in clustering power spectra
Nicolas Tessore, Alex Hall
We show that the `shot noise' bias in angular clustering power spectra observed from discrete samples of points is not noise, but rather a known additive contribution that naturall…
Confronting primordial black holes with LIGO-Virgo-KAGRA and the Einstein Telescope
Zu-Cheng Chen, Alex Hall
The detection of gravitational waves (GWs) from binary black hole (BBH) coalescences by the LIGO-Virgo-KAGRA (LVK) Collaboration has raised fundamental questions about the genesis…
Arrow's Impossibility Theorem: Computability in Social Choice Theory
Alex Hall
Arrow's Impossibility Theorem establishes bounds on what we can require from voting systems. Given satisfaction of a small collection of "fairness" axioms, it shows votes can only…
