Exploring the constraints on cosmological models with CosmoEJS
Jacob Moldenhauer, Francis Cavanna, William O'toole +1
We introduce new CosmoEJS modules to improve the investigation of the consequences of constraints on the parameter values of cosmological models. We use CosmoMC to fit dark energy…
Modern Cosmology: Interactive Computer Simulations that use Recent Observational Surveys
Jacob Moldenhauer, Larry Engelhardt, Keenan Stone +1
We present a collection of new, open-source computational tools for numerically modeling recent large-scale observational data sets using modern cosmology theory. Specifically, the…
Testing General Relativity at Cosmological Scales: Implementation and Parameter Correlations
Jason Dossett, Mustapha Ishak, Jacob Moldenhauer
The testing of general relativity at cosmological scales has become a possible and timely endeavor that is not only motivated by the pressing question of cosmic acceleration but al…
Figures of merit and constraints from testing General Relativity using the latest cosmological data sets including refined COSMOS 3D weak lensing
Jason Dossett, Jacob Moldenhauer, Mustapha Ishak
We use cosmological constraints from current data sets and a figure of merit (FoM) approach to probe any deviations from general relativity (GR) at cosmological scales. The FoM app…
Constraints on growth index parameters from current and future observations
Jason Dossett, Mustapha Ishak, Jacob Moldenhauer +2
We use current and future simulated data of the growth rate of large scale structure in combination with data from supernova, BAO, and CMB surface measurements, in order to put con…
Supernova, baryon acoustic oscillations, and CMB surface distance constraints on f(G) higher order gravity models
Jacob Moldenhauer, Mustapha Ishak, John Thompson +1
We consider recently proposed higher order gravity models where the action is built from the Einstein-Hilbert action plus a function f(G) of the Gauss-Bonnet invariant. The models…
A minimal set of invariants as a systematic approach to higher order gravity models: Physical and Cosmological Constraints
Jacob Moldenhauer, Mustapha Ishak
We compare higher order gravity models to observational constraints from magnitude-redshift supernova data, distance to the last scattering surface of the CMB, and Baryon Acoustic…
A minimal set of invariants as a systematic approach to higher order gravity models
Mustapha Ishak, Jacob Moldenhauer
Higher-order gravity models have been recently the subject of much attention in the context of cosmic acceleration. These models are derived by adding various curvature invariants…
A New Independent Limit on the Cosmological Constant/Dark Energy from the Relativistic Bending of Light by Galaxies and Clusters of Galaxies
Mustapha Ishak, Wolfgang Rindler, Jason Dossett +2
We derive new limits on the value of the cosmological constant, , based on the Einstein bending of light by systems where the lens is a distant galaxy or a cluster of galaxies.…
