Parameters that quantify the acceleration of cosmic expansion are conventionally
determined within the standard Friedmann–Lemaître–Robertson–Walker (FLRW) model …

We discuss the discordance between the estimated values of the cosmological parameters
from Planck assuming the concordance ΛCDM model and low-redshift measurements. In …

The Planck collaboration has measured the temperature and polarization of the cosmic
microwave background well enough to determine the locations of eight peaks in the …

Non-parametric reconstruction methods, such as Gaussian process (GP) regression, provide
a model-independent way of estimating an underlying function and its uncertainty from noisy …

We present a novel approach to test the consistency of the cosmological models with
multiband CMB data using a nonparametric approach. In our analysis we calibrate the …

Astrophysics faces two critical challenges: the difficulty of observing very distant targets and
the difficulty of interpreting science in diverse and often extreme environments that have not …

We introduce a generalization of the 4− dimensional averaging window function of
Gasperini, Marozzi and Veneziano (2010) that may prove useful for a number of …
