Spectral distortion constraints on photon injection from low-mass decaying particles
Boris Bolliet, Jens Chluba, Richard Battye
Spectral distortions (SDs) of the cosmic microwave background (CMB) provide a powerful tool for studying particle physics. Here we compute the distortion signals from decaying part…
The Simons Observatory: gain, bandpass and polarization-angle calibration requirements for B-mode searches
Maximilian H. Abitbol, David Alonso, Sara M. Simon +45
We quantify the calibration requirements for systematic uncertainties for next-generation ground-based observatories targeting the large-angle -mode polarization of the Cosmic M…
Removing the giants and learning from the crowd: a new SZ power spectrum method and revised Compton -map analysis
Aditya Rotti, Boris Bolliet, Jens Chluba +1
The Sunyaev-Zeldovich (SZ) effect provides a powerful cosmological probe, which traditionally is approached independently as cluster number count (CNC) or power spectrum (PS) analy…
Bridging the gap: spectral distortions meet gravitational waves
Thomas Kite, Andrea Ravenni, Subodh P. Patil +1
Gravitational waves (GWs) have the potential to probe the entirety of cosmological history due to their nearly perfect decoupling from the thermal bath and any intervening matter a…
Cosmology Intertwined IV: The Age of the Universe and its Curvature
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +88
A precise measurement of the curvature of the Universe is of primeval importance for cosmology since it could not only confirm the paradigm of primordial inflation but also help in…
Cosmology Intertwined III: and
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +89
The standard Cold Dark Matter cosmological model provides a wonderful fit to current cosmological data, but a few tensions and anomalies became statistically significant with t…
