A stochastic background of gravitational waves could be created by the superposition of a
large number of independent sources. The physical processes occurring at the earliest …

▪ Abstract Cosmic microwave background (CMB) temperature anisotropies have and will
continue to revolutionize our understanding of cosmology. The recent discovery of the …

ABSTRACT WMAP precision data enable accurate testing of cosmological models. We find
that the emerging standard model of cosmology, a flat Λ-dominated universe seeded by a …

We present the large-scale correlation function measured from a spectroscopic sample of
46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers …

A simple cosmological model with only six parameters (matter density, Ω mh 2, baryon
density, Ω bh 2, Hubble constant, H 0, amplitude of fluctuations, σ 8, optical depth, τ, and a …

We present a fast Markov chain Monte Carlo exploration of cosmological parameter space.
We perform a joint analysis of results from recent cosmic microwave background (CMB) …

We have discovered 21 new Type Ia supernovae (SNe Ia) with the Hubble Space Telescope
(HST) and have used them to trace the history of cosmic expansion over the last 10 billion yr …

We place constraints on the redshift-averaged, effective value of the equation of state of dark
energy, w, using only the absolute ages of Galactic stars and the observed position of the …

Markov chain Monte Carlo–based Bayesian data analysis has now become the method of
choice for analyzing and interpreting data in almost all disciplines of science. In astronomy …

We present jax-cosmo, a library for automatically differentiable cosmological theory
calculations. It uses the JAX library, which has created a new coding ecosystem, especially …
