Observational probes of cosmic acceleration

DH Weinberg, MJ Mortonson, DJ Eisenstein, C Hirata… - Physics reports, 2013 - Elsevier
The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

Features and new physical scales in primordial observables: theory and observation

J Chluba, J Hamann, SP Patil - International Journal of Modern …, 2015 - World Scientific
All cosmological observations to date are consistent with adiabatic, Gaussian and nearly
scale invariant initial conditions. These findings provide strong evidence for a particular …

Large-scale clustering of galaxies in general relativity

D Jeong, F Schmidt, CM Hirata - … Review D—Particles, Fields, Gravitation, and …, 2012 - APS
Several recent studies have shown how to properly calculate the observed clustering of
galaxies in a relativistic context, and uncovered corrections to the Newtonian calculation that …

The nature of the diffuse gamma-ray background

M Fornasa, MA Sánchez-Conde - Physics Reports, 2015 - Elsevier
We review the current understanding of the Diffuse Gamma-Ray Background (DGRB). The
DGRB is what remains of the total measured gamma-ray emission after the subtraction of the …

A first application of the Alcock–Paczynski test to stacked cosmic voids

PM Sutter, G Lavaux, BD Wandelt… - The Astrophysical …, 2012 - iopscience.iop.org
We report on the first application of the Alcock–Paczynski test to stacked voids in
spectroscopic galaxy redshift surveys. We use voids from the Sutter et al. void catalog, which …

The new horizon run cosmological N-body simulations

J Kim, C Park, G Rossi, SM Lee, JR Gott III - arXiv preprint arXiv …, 2011 - arxiv.org
We present two large cosmological N-body simulations, called Horizon Run 2 (HR2) and
Horizon Run 3 (HR3), made using 6000^ 3= 216 billions and 7210^ 3= 374 billion particles …

Cosmology with the large synoptic survey telescope: an overview

H Zhan, JA Tyson - Reports on Progress in Physics, 2018 - iopscience.iop.org
Abstract The Large Synoptic Survey Telescope (LSST) is a high étendue imaging facility that
is being constructed atop Cerro Pachón in northern Chile. It is scheduled to begin science …

Observational evidence of the accelerated expansion of the universe

P Astier, R Pain - Comptes Rendus Physique, 2012 - Elsevier
The discovery of cosmic acceleration is one of the most important developments in modern
cosmology. The observation, thirteen years ago, that type Ia supernovae appear dimmer that …

Bayesian high-redshift quasar classification from optical and mid-IR photometry

GT Richards, AD Myers, CM Peters… - The Astrophysical …, 2015 - iopscience.iop.org
ABSTRACT We identify 885,503 type 1 quasar candidates to i 22 using the combination of
optical and mid-IR photometry. Optical photometry is taken from the Sloan Digital Sky Survey …

Coarse-grained cosmological perturbation theory

M Pietroni, G Mangano, N Saviano… - Journal of Cosmology …, 2012 - iopscience.iop.org
Semi-analytical methods, based on Eulerian perturbation theory, are a promising tool to
follow the time evolution of cosmological perturbations at small redshifts and at mildly …
