recommendations! Published in 2020 at "Journal of Cosmology and Astroparticle Physics"

DOI: 10.1088/1475-7516/2021/03/036

Abstract: Measuring spectral distortions (SDs) of the cosmic microwave background (CMB) will provide new constraints on previously unexplored scales of the primordial power spectrum, allowing us to extend the probed parameter space by several orders of… read more here.

DOI: 10.1088/1475-7516/2021/12/050

Abstract: Measurements of the cosmic microwave background (CMB) spectral distortions (SDs) will open a new window on the very early universe, providing new information complementary to that gathered from CMB temperature and polarization anisotropies. In this… read more here.

DOI: 10.1103/physrevd.100.083021

Abstract: We compute the impact of the running of higher order density correlation functions on the two point functions of CMB spectral distortions (SD). We show that having some levels of running enhances all of the… read more here.

DOI: 10.1103/physrevlett.119.221102

Abstract: We present a general framework for the accurate spectral modeling of the low multipoles of the cosmic microwave background (CMB) as observed in a boosted frame. In particular, we demonstrate how spectral measurements of the… read more here.
