Infrared Sensitivity of Cosmological Probes In The Presence of Axion Field Fluctuations
Matteo Magi, Robert Brandenberger, Jaiyul Yoo
We study the effects of long wavelength entropy fluctuations on cosmological probes such as galaxy clustering, luminosity distance, and CMB temperature anisotropies. Specifically,…

Infrared Sensitivity of Cosmological Probes in Horndeski Theory
Matteo Magi, Jaiyul Yoo
Cosmological probes constructed in large-scale surveys are independent of the underlying theory of gravity, and their relativistic descriptions are indeed applicable to any theory…
