High resolution Lyman-α forest constraints on dark matter-neutrino scattering
Markus R. Mosbech, Olga Garcia-Gallego, Vid Iršič +2
We present new constraints on models of dark matter interacting with neutrino, based on high-resolution Lyman- forest data. We perform a suite of full hydrodynamical simulations…
The world cup. II. A comprehensive competition between proposed Hubble tension solutions
Nils Schöneberg, Vivian Poulin, Angelo G. Ferrari +6
Cosmology stands at a crossroads. The Hubble tension has reached a nominal significance above , while analyses combining DESI BAO and Type Ia supernova data show emerging hints…
The World Cup. I. Summary of the baseline group stage results
Nils Schöneberg, Vivian Poulin, Angelo G. Ferrari +6
The Hubble tension has reached a nominal significance above , while new high-precision measurements of the cosmic microwave background (CMB) and baryon acoustic oscillations (B…
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…
OLÉ -- Online Learning Emulation in Cosmology
Sven Günther, Lennart Balkenhol, Christian Fidler +4
In this work, we present OLÉ, a new online learning emulator for use in cosmological inference. The emulator relies on Gaussian Processes and Principal Component Analysis for effic…
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…
One trick to treat them all: SuperEasy linear response for any hot dark matter in -body simulations
Giovanni Pierobon, Markus R. Mosbech, Amol Upadhye +1
We generalise the SuperEasy linear response method, originally developed to describe massive neutrinos in cosmological -body simulations, to any hot dark matter (HDM) species wi…
Everything hot everywhere all at once: Neutrinos and hot dark matter as a single effective species
Amol Upadhye, Markus R. Mosbech, Giovanni Pierobon +1
Observational cosmology is rapidly closing in on a measurement of the sum M_nu of neutrino masses, at least in the simplest cosmologies, while opening the door to probes of non-sta…
DESI forecast for Dark Matter-Neutrino interactions using EFTofLSS
Markus R. Mosbech, Santiago Casas, Julien Lesgourgues +4
We apply the Effective Field Theory of Large Scale Structure (EFTofLSS) to non-standard models of dark matter with suppressed small-scale structure imprinted by early-time physics,…
Hybrid multi-fluid-particle simulations of the cosmic neutrino background
Joe Zhiyu Chen, Markus R. Mosbech, Amol Upadhye +1
Simulation of the cosmic clustering of massive neutrinos is a daunting task, due both to their large velocity dispersion and to their weak clustering power becoming swamped by Pois…
Gravitational-wave event rates as a new probe for dark matter microphysics
Markus R. Mosbech, Alexander C. Jenkins, Sownak Bose +3
We show that gravitational waves have the potential to unravel the microphysical properties of dark matter due to the dependence of the binary black hole merger rate on cosmic stru…
Probing dark matter interactions with 21cm observations
Markus R. Mosbech, Celine Boehm, Yvonne Y. Y. Wong
Similarly to warm dark matter which features a cut-off in the matter power spectrum due to free-streaming, many interacting dark matter models predict a suppression of the matter p…
The full Boltzmann hierarchy for dark matter-massive neutrino interactions
Markus R. Mosbech, Celine Boehm, Steen Hannestad +3
The impact of dark matter-neutrino interactions on the measurement of the cosmological parameters has been investigated in the past in the context of massless neutrinos exclusively…
