The Galactic Center is an excellent laboratory for studying phenomena and physical
processes that may be occurring in many other galactic nuclei. The center of our Milky Way …

The ordering of the neutrino masses is a crucial input for a deep understanding of flavor
physics, and its determination may provide the key to establish the relationship among the …

ABSTRACT The Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data provide
stringent limits on deviations from the minimal, six-parameter Λ cold dark matter model. We …

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 measure the large-scale real-space power spectrum P (k) using luminous red galaxies
(LRGs) in the Sloan Digital Sky Survey (SDSS) and use this measurement to sharpen …

We present Fisher matrix projections for future cosmological parameter measurements,
including neutrino masses, Dark Energy, curvature, modified gravity, the inflationary …

We explore cosmological constraints on the sum of the three active neutrino masses M ν in
the context of dynamical dark energy (DDE) models with equation of state (EoS) …

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 a new limit of∑ m ν≤ 0.28 (95% CL) on the sum of the neutrino masses
assuming a flat Λ CDM cosmology. This relaxes slightly to∑ m ν≤ 0.34 and∑ m ν≤ 0.47 …

We present robust, model-marginalized limits on both the total neutrino mass (∑ m ν) and
abundances (N eff) to minimize the role of parametrizations, priors and models when …
