CMBPol Mission Concept Study Probing Ination with CMB Polarization
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of ination. We focus on the prospects for using CMB measurements
A fraction of the extragalactic near-infrared (near-IR) background light involves redshifted photons from the ultraviolet (UV) emission from galaxies present during reionization at redshifts above 6.
CMB-S4 Science Case, Reference Design, and Project Plan
We present the science case, reference design, and project plan for the Stage-4 ground-based cosmic microwave background experiment CMB-S4.
Halo model at its best: constraints on conditional luminosity functions from measured galaxy statistics
Using the conditional luminosity function (CLF; the luminosity distribution of galaxies in a dark matter halo) as the fundamental building block, we present an empirical model for the galaxy
The average physical properties and star formation histories of the UV-brightest star-forming galaxies at z ~ 3.7
We investigate the average physical properties and star formation histories (SFHs) of the most UV-luminous star-forming galaxies at z {approx} 3.7. Our results are based on the average spectral
What is L? Anatomy of the Galaxy Luminosity Function
Using the empirical relations between the central galaxy luminosity and the halo mass, and between the total galaxy luminosity in a halo and the halo mass, we construct the galaxy luminosity function
Testing general relativity with current cosmological data
Deviations from general relativity, such as could be responsible for the cosmic acceleration, would influence the growth of large-scale structure and the deflection of light by that structure. We
Cluster Merger Variance and the Luminosity Gap Statistic
The presence of multiple luminous galaxies in clusters can be explained by the finite time over which a galaxy sinks to the center of the cluster and merges with the central galaxy. The simplest
iPTF16geu: A multiply imaged, gravitationally lensed type Ia supernova
A type Ia supernova is identified that is strongly lensed by a foreground galaxy, causing it to be highly magnified and splitting the light into four separate images, a well-studied variety with reliable properties that can be used to constrain models of the lensing.
Uncorrelated estimates of dark energy evolution
Type Ia supernova data have recently become strong enough to enable, for the first time, constraints on the time variation of the dark energy density and its equation of state. Most analyses,
