Testing Inflation with Large Scale Structure: Connecting Hopes with Reality
Marcelo Alvarez, Tobias Baldauf, J. Richard Bond +25
The statistics of primordial curvature fluctuations are our window into the period of inflation, where these fluctuations were generated. To date, the cosmic microwave background h…
Probing Satellite Quenching With Galaxy Clustering
Robert T. Chamberlain, Neal Dalal, Andrew Hearin +1
Satellites within simulated massive clusters are significantly spatially correlated with each other, even when those satellites are not gravitationally bound to each other. This co…
Three-point galaxy-galaxy lensing as a probe of dark matter halo shapes
Susmita Adhikari, Chun Yin Ricky Chue, Neal Dalal
We propose a method to measure the ellipticities of dark matter halos using the lens-shear-shear 3-point correlation function. This method is immune to effects of galaxy-halo misal…
Measuring the power spectrum of dark matter substructure using strong gravitational lensing
Yashar Hezaveh, Neal Dalal, Gilbert Holder +3
In recent years, it has become possible to detect individual dark matter subhalos near images of strongly lensed extended background galaxies. Typically, only the most massive subh…
Higher moments of primordial non-Gaussianity and N-body simulations
Saroj Adhikari, Sarah Shandera, Neal Dalal
We perform cosmological N-body simulations with non-Gaussian initial conditions generated from two independent fields. The dominant contribution to the perturbations comes from a p…
