Boosting the optical depth to Thomson scattering with primordial black hole evaporation at high redshift
Isaac Sierra, Gabriel P. Lynch, Lloyd Knox +3
BAO and CMB data are somewhat discrepant when interpreted in the context of cdm, discrepancies that show up as a `matter density deficit' and as a `CMB lensing excess'. One pos…
What could an emerging Big Bang Nucleosynthesis discrepancy be hinting at?
Vivian Poulin, Julien Froustey, Cyril Pitrou +1
The latest measurement of the primordial deuterium abundance is in tension with several state-of-the-art predictions of standard Big Bang nucleosynthesis (BBN), when usi…
The road towards precision measurements of with bright sirens in the Einstein Telescope era
Chiara De Leo, Elsa M. Teixeira, Vivian Poulin
Gravitational-wave standard sirens provide an independent probe of cosmic expansion since their luminosity distances are inferred directly from the gravitational-wave signal and, f…
Decaying Dark Matter Halo Abundance from a Revised Spherical Collapse Model
Thomas Montandon, Vivian Poulin, Oliver Hahn +2
We present a semi-analytical framework for the halo mass function (HMF) in decaying dark matter (DDM) cosmologies, in which dark matter decays into a massive daughter particle inhe…
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…
