High resolution Lyman-α forest constraints on dark matter-neutrino scattering
Markus R. Mosbech, Olga Garcia-Gallego, Vid IrÅ¡iÄ +2
The paper uses high‑resolution Lyman‑α forest data and a suite of hydrodynamical simulations to place the strongest direct limits to date on dark matter–neutrino scattering, findin…
The world cup. II. A comprehensive competition between proposed Hubble tension solutions
Nils Schöneberg, Vivian Poulin, Angelo G. Ferrari +6
The paper systematically compares fourteen proposed solutions to the Hubble tension using a common set of CMB, BAO, and supernova data, evaluating their performance with Bayesian a…
The World Cup. I. Summary of the baseline group stage results
Nils Schöneberg, Vivian Poulin, Angelo G. Ferrari +6
The paper evaluates fourteen extensions to the standard ΛCDM cosmology against recent CMB, BAO, and supernova data to see which can reduce the Hubble‑constant tension, finding that…
Cosmological constraints on TeV-scale dark matter subcomponents decaying between recombination and reionisation
Markus R. Mosbech, Cristina Benso, Felix Kahlhoefer
The Dark Ages and the Cosmic Dawn are an untapped well of information about the particle physics properties of dark matter, which may become accessible with future radio telescopes…
OLÃ -- Online Learning Emulation in Cosmology
Sven Günther, Lennart Balkenhol, Christian Fidler +4
In this work, we present OLÃ, a new online learning emulator for use in cosmological inference. The emulator relies on Gaussian Processes and Principal Component Analysis for effi…
Emulating the Lyman-Alpha forest 1D power spectrum from cosmological simulations: New models and constraints from the eBOSS measurement
Michael Walther, Nils Schöneberg, Solène Chabanier +8
We present the Lyssa suite of high-resolution cosmological simulations of the Lyman- forest designed for cosmological analyses. These 18 simulations have been run using the Nyx…
