Cosmology with Galaxy Photometry Alone
ChangHoon Hahn, Francisco Villaescusa-Navarro, Peter Melchior +1
We present the first cosmological constraints using only the observed photometry of galaxies. Villaescusa-Navarro et al. (2022; arXiv:2201.02202) recently demonstrated that the int…
Galaxies Going Bananas: Inferring the 3D Geometry of High-Redshift Galaxies with JWST-CEERS
Viraj Pandya, Haowen Zhang, Marc Huertas-Company +53
The 3D geometry of high-redshift galaxies remains poorly understood. We build a differentiable Bayesian model and use Hamiltonian Monte Carlo to efficiently and robustly infer the…
Cosmology with multiple galaxies
Chaitanya Chawak, Francisco Villaescusa-Navarro, Nicolas Echeverri Rojas +3
Recent works have discovered a relatively tight correlation between and properties of individual simulated galaxies. Because of this, it has been shown that constraints…
PopSED: Population-Level Inference for Galaxy Properties from Broadband Photometry with Neural Density Estimation
Jiaxuan Li, Peter Melchior, ChangHoon Hahn +1
We present PopSED, a framework for the population-level inference of galaxy properties from photometric data. Unlike the traditional approach of first analyzing individual galaxies…
