Big bang nucleosynthesis (BBN) describes the production of the lightest nuclides via a
dynamic interplay among the four fundamental forces during the first seconds of cosmic time …

Within the Local Universe galaxies can be studied in great detail star by star, and here we
review the results of quantitative studies in nearby dwarf galaxies. The color-magnitude …

We assess the status of big-bang nucleosynthesis (BBN) in light of the final Planck data
release and other recent developments, and in anticipation of future measurements. Planck …

The Review summarizes much of particle physics and cosmology. Using data from previous
editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average …

Observations of helium and hydrogen emission lines from metal-poor extragalactic H II
regions, combined with estimates of metallicity, provide an independent method for …

We update the constraints on the fraction of the Universe going into primordial black holes in
the mass range 10 9–10 17 g associated with the effects of their evaporations on big bang …

This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …

We present MMT spectroscopic observations of H ii regions in 42 low luminosity galaxies in
the Spitzer Local Volume Legacy survey. For 31 of the 42 galaxies in our sample, we were …

We present a measurement of the angular power spectrum of the cosmic microwave
background (CMB) using data from the South Pole Telescope (SPT). The data consist of 790 …

We present an up-to-date review of Big Bang Nucleosynthesis (BBN). We discuss the main
improvements which have been achieved in the past two decades on the overall theoretical …
