Lensing corrections on galaxy-lensing cross correlations and galaxy-galaxy auto correlations
Vanessa Böhm, Chirag Modi, Emanuele Castorina
We study the impact of lensing corrections on modeling cross correlations between CMB lensing and galaxies, cosmic shear and galaxies, and galaxies in different redshift bins. Esti…
Generative Learning of Counterfactual for Synthetic Control Applications in Econometrics
Chirag Modi, Uros Seljak
A common statistical problem in econometrics is to estimate the impact of a treatment on a treated unit given a control sample with untreated outcomes. Here we develop a generative…
Simulations and symmetries
Chirag Modi, Shi-Fan Chen, Martin White
We investigate the range of applicability of a model for the real-space power spectrum based on N-body dynamics and a (quadratic) Lagrangian bias expansion. This combination uses t…
Reconstructing large-scale structure with neutral hydrogen surveys
Chirag Modi, Martin White, Anze Slosar +1
Upcoming 21-cm intensity surveys will use the hyperfine transition in emission to map out neutral hydrogen in large volumes of the universe. Unfortunately, large spatial scales are…
