An Accurate Fitting Function For Scale-dependent Growth Rate in Hu-Sawicki Gravity
Nareg Mirzatuny, Elena Pierpaoli
We present a simple fitting formula for the scale-dependent growth rate of Hu-Sawicki model in modified gravity. We compare the accuracy of the fitting function against nume…

Pairwise Transverse Velocity Measurement with the Rees-Sciama Effect
Siavash Yasini, Nareg Mirzatuny, Elena Pierpaoli
We introduce a new estimator for the mean pairwise velocities of galaxy clusters, which is based on the measurement of the clusters' velocity components. The…
