Using cosmic voids to distinguish f(R) gravity in future galaxy surveys

Paul Zivick, P. M. Sutter, Benjamin D. Wandelt +2

We use properties of void populations identified in -body simulations to forecast the ability of upcoming galaxy surveys to differentiate models of f(R) gravity from \lcdm~cosmo…

Voids in Modified Gravity Reloaded: Eulerian Void Assignment

Tsz Yan Lam, Joseph Clampitt, Yan-Chuan Cai +1

We revisit the excursion set approach to calculate void abundances in chameleon-type modified gravity theories, which was previously studied by Clampitt, Cai and Li (2013). We focu…

Modeling the Phase-Space Distribution around Massive Halos

Tsz Yan Lam, Fabian Schmidt, Takahiro Nishimichi +1

The comparison between dynamical mass and lensing mass provides a targeted test for a wide range of modified gravity models. In our previous paper we showed, through numerical simu…

Excursion set theory for modified gravity: Eulerian versus Lagrangian environments

Baojiu Li, Tsz Yan Lam

We have revisited the extended excursion set theory in modified gravity models, taking the chameleon model as an example. Instead of specifying their Lagrangian size, here we defin…

Excursion set theory for modified gravity: correlated steps, mass functions and halo bias

Tsz Yan Lam, Baojiu Li

We show how correlated steps introduces significant contributions to the modification of the halo mass function in modified gravity models, taking the chameleon models as an exampl…

A hierarchy of voids: More ado about nothing

Aseem Paranjape, Tsz Yan Lam, Ravi K. Sheth

We extend earlier work on the problem of estimating the void-volume function -- the abundance and evolution of large voids which grow gravitationally in an expanding universe -- in…
