Density profiles and voids in modified gravity models
Matthew C. Martino, Ravi K. Sheth
We study the formation of voids in a modified gravity model in which gravity is generically stronger or weaker on large scales. We show that void abundances provide complementary i…
On the equivalence between the effective cosmology and excursion set treatments of environment
Matthew C. Martino, Ravi K. Sheth
In studies of the environmental dependence of structure formation, the large scale environment is often thought of as providing an effective background cosmology: e.g. the formatio…
Spherical Collapse and Cluster Counts in Modified Gravity Models
Matthew C. Martino, Hans F. Stabenau, Ravi K. Sheth
Modifications to the gravitational potential affect the nonlinear gravitational evolution of large scale structures in the Universe. To illustrate some generic features of such cha…
Satellite Luminosities in Galaxy Groups
Ramin A. Skibba, Ravi K. Sheth, Matthew C. Martino
Halo model interpretations of the luminosity dependence of galaxy clustering assume that there is a central galaxy in every sufficiently massive halo, and that this central galaxy…
