FOSSIL: A future mission for CMB spectral distortion measurements

N. Aghanim, B. Maffei, J. Aumont +96

We present FOSSIL, a proposed space mission which is designed to deliver unprecedented absolute spectroscopic measurements of the sky intensity over a broad frequency range (50GHz…

Peering Beyond the Veil of Last Scattering: A View of the Universe with CMB Spectral Distortions

Bryce Cyr, Nabila Aghanim, Ethan Baker +37

The frequency spectrum of the cosmic microwave background is the most precise blackbody ever measured in nature, with deviations constrained at the level of almost one part per mil…

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 poss…

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 usin…

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…
