We present constraints on the tensor-to-scalar ratio r using a combination of BICEP/Keck
2018 (BK18) and Planck PR4 data allowing us to fit for r consistently with the six parameters …

Since the discovery of the accelerated expansion of the present universe, significant
theoretical developments have been made in the area of modified gravity. In the meantime …

If dark matter is composed of axions, then axion stars form in the cores of dark matter halos.
These stars are unstable above a critical mass, decaying to radio photons that heat the …

This review is devoted to recent developments in the statistical analysis of spherical data,
strongly motivated by applications in cosmology. We start from a brief discussion of …

We present a detailed overview of the science goals and predictions for the Prime-Cam
direct-detection camera–spectrometer being constructed by the CCAT-prime collaboration …

We find several missing one-loop-order contributions in previous considerations about
secondary gravitational waves induced at nonlinear order in cosmological perturbations. We …

In this paper, we formulate a generalised photon Boltzmann hierarchy that allows us to
model the evolution and creation of spectral distortion anisotropies caused by energy …

The recent observations from the James Webb Space Telescope have led to a surprising
discovery of a significant density of massive galaxies with masses of M≥ 10 10.5 M⊙ at …

We study reheating of inflationary models with general non-minimal coupling K (ϕ) R with K
(ϕ)∼√(V (ϕ)) where R is the Ricci scalar and R is the inflaton potential. In particular, when …

A realistic model of SU (5)× U (1) χ, embedded in SO (10) supersymmetric grand unified
theory, is investigated for the emergence of a metastable cosmic string network. This …
