Improvements to Inference Compilation for Probabilistic Programming in Large-Scale Scientific Simulators
Mario Lezcano Casado, Atilim Gunes Baydin, David Martinez Rubio +8
We consider the problem of Bayesian inference in the family of probabilistic models implicitly defined by stochastic generative models of data. In scientific fields ranging from po…
Offsets between member galaxies and dark matter in clusters: a test with the Illustris simulation
Karen Y. Ng, Annalisa Pillepich, David Wittman +3
Dark matter with a non-zero self-interacting cross section () has been posited as a solution to a number of outstanding astrophysical mysteries. Many studies of mergi…
Probabilistic Cosmological Mass Mapping from Weak Lensing Shear
Michael D. Schneider, Karen Y. Ng, William A. Dawson +3
We infer gravitational lensing shear and convergence fields from galaxy ellipticity catalogs under a spatial process prior for the lensing potential. We demonstrate the performance…
The return of the merging galaxy subclusters of El Gordo?
Karen Y. Ng, William A. Dawson, D. Wittman +4
Merging galaxy clusters with radio relics provide rare insights to the merger dynamics as the relics are created by the violent merger process. We demonstrate one of the first uses…
Weighing "El Gordo" with a Precision Scale: Hubble Space Telescope Weak-lensing Analysis of the Merging Galaxy Cluster ACT-CL J0102-4915 at z=0.87
M. James Jee, John P. Hughes, Felipe Menanteau +5
(Abridged) We present a HST weak-lensing study of the merging galaxy cluster "El Gordo" (ACT-CL J0102-4915) at z=0.87 discovered by the Atacama Cosmology Telescope collaboration as…
