The abundance of voids and the excursion set formalism
We present measurements of the number density of voids in the dark matter distribution from a series of N-body simulations of a ΛCDM cosmology. We define voids as spherical regions of ρv = 0.2ρm around density minima in order to relate our results to the predicted abundances using the excursion set formalism. Using a linear underdensity of δv = −2.7, from a spherical evolution model, we find th...
متن کاملObservationally Verifiable Predictions of Modified Gravity
MOG is a fully relativistic modified theory of gravity based on an action principle. The MOG field equations are exactly solvable numerically in two important cases. In the spherically symmetric, static case of a gravitating mass, the equations also admit an approximate solution that closely resembles the Reissner-Nordström metric. Furthermore, for weak gravitational fields, a Yukawa-type modif...
متن کاملShapes and Sizes of Voids in the Λ CDM Universe : Excursion Set Approach
We study the global distribution and morphology of dark matter voids in a ΛCDM universe using density fields generated by N-body simulations. Voids are defined as isolated regions of the low-density excursion set specified via density thresholds, the density thresholds being quantified by the corresponding filling factors, i.e., the fraction of the total volume in the excursion set. Our work en...
متن کاملThe evidence of absence: galaxy voids in the excursion set formalism
We present an analytic model for the sizes of voids in the galaxy distribution. Peebles and others have recently emphasized the possibility that the observed characteristics of voids may point to a problem in galaxy formation models, but testing these claims has been difficult without any clear predictions for their properties. In order to address such questions, we build a model to describe th...
متن کاملTime Delay Predictions in a Modified Gravity Theory
The time delay effect for planets and spacecraft is obtained from a fully relativistic modified gravity theory including a fifth force skew symmetric field by fitting to the Pioneer 10/11 anomalous acceleration data. A possible detection of the predicted time delay corrections to general relativity for the outer planets and future spacecraft missions is considered. The time delay correction to ...
