DESI and the Hubble tension in light of modified recombination
Gabriel P. Lynch, Lloyd Knox, Jens Chluba
Recent measurements and analyses from the Dark Energy Spectroscopic Instrument (DESI) Collaboration and supernova surveys combined with cosmic microwave background (CMB) observatio…
Reconstructing the recombination history by combining early and late cosmological probes
Gabriel P. Lynch, Lloyd Knox, Jens Chluba
We develop and apply a new framework for reconstructing the ionization history during the epoch of recombination with combinations of cosmic microwave background (CMB), baryon acou…
Cosmology Intertwined II: The Hubble Constant Tension
Eleonora Di Valentino, Luis A. Anchordoqui, Ozgur Akarsu +90
The current cosmological probes have provided a fantastic confirmation of the standard Cold Dark Matter cosmological model, that has been constrained with unprecedented accurac…
SPT-GMOS: A Gemini/GMOS-South Spectroscopic Survey of Galaxy Clusters in the SPT-SZ Survey
M. B. Bayliss, J. Ruel, C. W. Stubbs +75
We present the results of SPT-GMOS, a spectroscopic survey with the Gemini Multi-Object Spectrograph (GMOS) on Gemini South. The targets of SPT-GMOS are galaxy clusters identified…
Planck intermediate results. XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes
Planck Collaboration, R. Adam, P. A. R. Ade +230
The polarized thermal emission from Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background (CMB) at frequencies above 1…
Planck 2013 results. XXV. Searches for cosmic strings and other topological defects
Planck Collaboration, P. A. R. Ade, N. Aghanim +225
Planck data have been used to provide stringent new constraints on cosmic strings and other defects. We describe forecasts of the CMB power spectrum induced by cosmic strings, calc…
