Cosmic Growth and Expansion Conjoined

Linder, Eric V. (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2016-10-17)

Cosmological measurements of both the expansion history and growth history have matured, and the two together provide an important test of general relativity. We consider their joint evolutionary track, showing that this ...
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: constraining modi ed gravity

Mueller, Eva-Maria; Percival, Will; Linder, Eric; Alam, Shadab; Zhao, Gong-Bo; Sanchez, Ariel G.; Beutler, Florian (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2016-12-02)

We use baryon acoustic oscillation and redshift space distortion from the completed Baryon Oscillation Spectroscopic Survey, corresponding to data release 12 of the Sloan Digital Sky Survey, combined sample analysis in ...
Cosmic Growth Signatures of Modified Gravitational Strength

Denissenya, Mikhail; Linder, Eric V. (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2017-03-02)

Cosmic growth of large scale structure probes the entire history of cosmic expansion and gravitational coupling. To get a clear picture of the effects of modification of gravity we consider a deviation in the coupling ...
Λ is Coming: Parametrizing Freezing Fields

Linder, Eric V. (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2017-03-21)

We explore freezing dark energy, where the evolution of the field approaches that of a cosmological constant at late times. We propose two general, two parameter forms to describe the class of freezing field models, in ...
Constraining Dark Energy Dynamics in Extended Parameter Space

Valentino, Eleonora Di; Melchiorri, Alessandro; Linder, Eric V.; Silk, Joseph (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2017-04-03)

Dynamical dark energy has been recently suggested as a promising and physical way to solve the 3 sigma tension on the value of the Hubble constant H0 between the direct measurement of Riess et al. (2016) (R16, hereafter) ...
Accelerated Parameter Estimation with DALEX

Daniel, Scott F.; Linder, Eric V. (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2017-05-02)

We consider methods for improving the estimation of constraints on a high-dimensional parameter space with a computationally expensive likelihood function. In such cases, Markov chain Monte Carlo (MCMC) can take a long ...
Slicing the Vacuum: New Accelerating Mirror Solutions of the Dynamical Casimir Effect

Good, Michael R.R.; Linder, Eric V. (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2017-07-17)

Radiation from accelerating mirrors in a Minkowski spacetime provides insights into the nature of horizons, black holes, and entanglement entropy. We introduce new, simple, symmetric and analytic moving mirror solutions ...
Witnessing the reionization history using Cosmic Microwave Background observation from Planck

Hazra, Dhiraj Kumar; Smoot, George F. (International conference "ECL17: Exploring the Energetic Universe 2017", Nazarbayev University Energetic Cosmic Laboratory, 2017-08-16)

We constrain the history of reionization using the data from Planck 2015 Cosmic Microwave Background (CMB) temperature and polarization anisotropy observations. We also use prior constraints on the reionization history at ...
