Forecasting Dark Matter Subhalo Constraints from Stellar Streams using Implicit Likelihood Inference
Tri Nguyen, Rutong Pei, Zhuofu Li +9
The evidence for dark matter (DM) remains compelling, although attempts to understand its particle nature remain inconclusive. One promising method to study DM is detecting DM subh…
The isotropy of Hubble expansion in the early and late Universe
Alan Junzhe Zhou, Scott Dodelson, Daniel Scolnic
We test the isotropy of Hubble expansion by combining several probes for the first time, constructing full-sky maps of expansion rate variation using Type Ia supernovae, fundamenta…
Map-level baryonification: unified treatment of weak lensing two-point and higher-order statistics
Alan Junzhe Zhou, Marco Gatti, Dhayaa Anbajagane +3
Precision cosmology benefits from extracting maximal information from cosmic structures, motivating the use of higher-order statistics (HOS) at small spatial scales. However, predi…
A Hamiltonian, post-Born, three-dimensional, on-the-fly ray tracing algorithm for gravitational lensing
Alan Junzhe Zhou, Yin Li, Scott Dodelson +4
The analyses of the next generation cosmological surveys demand an accurate, efficient, and differentiable method for simulating the universe and its observables across cosmologica…
Accurate field-level weak lensing inference for precision cosmology
Alan Junzhe Zhou, Xiangchong Li, Scott Dodelson +1
We present , a catalog-to-cosmology pipeline for general flat-sky field-level inference, which provides access to cosmological information beyond the two-point stati…
