Revealing the neutrino mass through persistent homology of the cosmic web
Jiaqi Wang, Willem Elbers, Carlos S. Frenk +4
Cosmological constraints on neutrino mass offer a promising avenue for advancing our understanding of both fundamental particle physics and the evolution of cosmic large-scale stru…
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…
Cosmological Constraints from Full-Scale Clustering and Galaxy-Galaxy Lensing with DESI DR1
Johannes U. Lange, Alexandra Wells, Andrew Hearin +76
We present constraints on cosmic structure growth from the analysis of galaxy clustering and galaxy-galaxy lensing with galaxies from the Dark Energy Spectroscopic Instrument (DESI…
Analytical and EZmock covariance validation for the DESI 2024 results
Daniel Forero-Sánchez, Michael Rashkovetskyi, Otávio Alves +44
The estimation of uncertainties in cosmological parameters is an important challenge in Large-Scale-Structure (LSS) analyses. For standard analyses such as Baryon Acoustic Oscillat…
Dynamical Dark Energy in light of the DESI DR2 Baryonic Acoustic Oscillations Measurements
Gan Gu, Xiaoma Wang, Yuting Wang +57
Understanding whether cosmic acceleration arises from a cosmological constant or a dynamical component is a central goal of cosmology, and the Dark Energy Spectroscopic Instrument…
Frequentist Cosmological Constraints from Full-Shape Clustering Measurements in DESI DR1
James Morawetz, Hanyu Zhang, Marco Bonici +56
We present a frequentist analysis of clustering measurements from Data Release 1 of the Dark Energy Spectroscopic Instrument (DESI) using the standard profile likelihood method. Wh…
