Do fast stellar centroiding methods saturate the Cramér-Rao lower bound?
Mohammadjavad Vakili, David W. Hogg
One of the most demanding tasks in astronomical image processing---in terms of precision---is the centroiding of stars. Upcoming large surveys are going to take images of billions…
How are galaxies assigned to halos? Searching for assembly bias in the SDSS galaxy clustering
Mohammadjavad Vakili, ChangHoon Hahn
Clustering of dark matter halos has been shown to depend on halo properties beyond mass such as halo concentration, a phenomenon referred to as halo assembly bias. Standard halo oc…
Approximate Bayesian Computation in Large Scale Structure: constraining the galaxy-halo connection
ChangHoon Hahn, Mohammadjavad Vakili, Kilian Walsh +3
Standard approaches to Bayesian parameter inference in large scale structure assume a Gaussian functional form (chi-squared form) for the likelihood. This assumption, in detail, ca…
