Bayesian evidence comparison for distance scale estimates
Aseem Paranjape, Ravi K. Sheth
Constraints on cosmological parameters are often distilled from sky surveys by fitting templates to summary statistics of the data that are motivated by a fiducial cosmological mod…
Optimal Transport Reconstruction of Baryon Acoustic Oscillations
Farnik Nikakhtar, Ravi K. Sheth, Bruno Lévy +1
A weighted, semi-discrete, fast optimal transport (OT) algorithm for reconstructing the Lagrangian positions of proto-halos from their evolved Eulerian positions is presented. The…
The half mass radius of MaNGA galaxies: Effect of IMF gradients
M. Bernardi, R. K. Sheth, H. Dominguez Sanchez +3
Gradients in the stellar populations (SP) of galaxies -- e.g., in age, metallicity, stellar Initial Mass Function (IMF) -- can result in gradients in the stellar mass to light rati…
