Sweeping Horndeski Canvas: New Growth-Rate Parameterization for Modified-Gravity Theories
Yuewei Wen, Nhat-Minh Nguyen, Dragan Huterer
We propose and numerically validate a new fitting formula that is sufficiently accurate to model the growth of structure in Horndeski theories of modified gravity for upcoming Stag…

Evidence for suppression of structure growth in the concordance cosmological model
Nhat-Minh Nguyen, Dragan Huterer, Yuewei Wen
We present evidence for a suppressed growth rate of large-scale structure during the dark-energy dominated era. Modeling the growth rate of perturbations with the ``growth index''…
