Hints, neutrino bounds and WDM constraints from SDSS DR14 Lyman- and Planck full-survey data
Nathalie Palanque-Delabrouille, Christophe Yèche, Nils Schöneberg +4
The Ly- forest 1D flux power spectrum is a powerful probe of several cosmological parameters. Assuming a CDM cosmology including massive neutrinos, we find that the latest SD…
Neutrino clustering in the Milky Way and beyond
P. Mertsch, G. Parimbelli, P. F. de Salas +3
The standard cosmological model predicts the existence of a Cosmic Neutrino Background, which has not yet been observed directly. Some experiments aiming at its detection are curre…
The synergy between CMB spectral distortions and anisotropies
Matteo Lucca, Nils Schöneberg, Deanna C. Hooper +2
Spectral distortions and anisotropies of the CMB provide independent and complementary probes to study energy injection processes in the early universe. Here we discuss the synergy…
New Horizons in Cosmology with Spectral Distortions of the Cosmic Microwave Background
J. Chluba, M. H. Abitbol, N. Aghanim +27
Voyage 2050 White Paper highlighting the unique science opportunities using spectral distortions of the cosmic microwave background (CMB). CMB spectral distortions probe many proce…
Microwave Spectro-Polarimetry of Matter and Radiation across Space and Time
Jacques Delabrouille, Maximilian H. Abitbol, Nabila Aghanim +77
This paper discusses the science case for a sensitive spectro-polarimetric survey of the microwave sky. Such a survey would provide a tomographic and dynamic census of the three-di…
The BAO+BBN take on the Hubble tension
Nils Schöneberg, Julien Lesgourgues, Deanna C. Hooper
Many attempts to solve the Hubble tension with extended cosmological models combine an enhanced relic radiation density, acting at the level of background cosmology, with new physi…
CosmicNet I: Physics-driven implementation of neural networks within Boltzmann-Einstein solvers
Jasper Albers, Christian Fidler, Julien Lesgourgues +2
Einstein-Boltzmann Solvers (EBSs) are run on a massive scale by the cosmology community when fitting cosmological models to data. We present a new concept for speeding up such code…
Constraining Dark Matter -- Dark Radiation interactions with CMB, BAO, and Lyman-
Maria Archidiacono, Deanna C. Hooper, Riccardo Murgia +3
Several interesting Dark Matter (DM) models invoke a dark sector leading to two types of relic particles, possibly interacting with each other: non-relativistic DM, and relativisti…
Including massive neutrinos in thermal Sunyaev Zeldovich power spectrum and cluster counts analyses
Boris Bolliet, Thejs Brinckmann, Jens Chluba +1
We consistently include the effect of massive neutrinos in the thermal Sunyaev Zeldovich (SZ) power spectrum and cluster counts analyses, highlighting subtle dependencies on the to…
Time-sliced perturbation theory with primordial non-Gaussianity and effects of large bulk flows on inflationary oscillating features
Anagha Vasudevan, Mikhail M. Ivanov, Sergey Sibiryakov +1
We extend the formalism of time-sliced perturbation theory (TSPT) for cosmological large-scale structure to include non-Gaussian initial conditions. We show that in such a case the…
Lensing anomalies from the epoch of reionisation
Christian Fidler, Julien Lesgourgues, Christophe Ringeval
Reionisation blurring is a non-linear correction to the cosmic microwave background that acts similar to weak gravitational lensing and that can be computed from linear perturbatio…
Status of Light Sterile Neutrino Searches
Sebastian Böser, Christian Buck, Carlo Giunti +5
A number of anomalous results in short-baseline oscillation may hint at the existence of one or more light sterile neutrino states in the eV mass range and have triggered a wave of…
Cosmological Probes of Dark Matter Interactions: The Next Decade
Vera Gluscevic, Yacine Ali-Haimoud, Keith Bechtol +16
Cosmological observations offer unique and robust avenues for probing the fundamental nature of dark matter particles-they broadly test a range of compelling theoretical scenarios,…
KiDS+GAMA: Constraints on Horndeski gravity from combined large-scale structure probes
Alessio Spurio Mancini, Fabian Köhlinger, Benjamin Joachimi +7
We present constraints on Horndeski gravity from a combined analysis of cosmic shear, galaxy-galaxy lensing and galaxy clustering from of the Kilo-Degree Surv…
