Less is less: photometry alone cannot predict the observed spectral indices of galaxies from the LEGA-C spectroscopic survey
Angelos Nersesian, Arjen van der Wel, Anna Gallazzi +9
We test whether we can predict optical spectra from deep-field photometry of distant galaxies. Our goal is to perform a comparison in data space, highlighting the differences betwe…

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…
