Reconstructing Quasar Spectra and Measuring the Ly Forest with
ChangHoon Hahn, Satya Gontcho A Gontcho, Peter Melchior +37
Quasar spectra carry the imprint of foreground intergalactic medium (IGM) through absorption features. In particular, absorption caused by neutral hydrogen gas, the ``Ly forest,…

Simulation-based inference of galaxy properties from JWST pixels
Patricia Iglesias-Navarro, Marc Huertas-Company, Pablo Pérez-González +6
We present an efficient Bayesian SED-fitting framework tailored to multiwavelength pixel photometry from the JWST Advanced Deep Extragalactic Survey (JADES). Our method employs sim…

Inhomogeneous Dust Biases Photometric Redshifts and Stellar Masses for LSST
ChangHoon Hahn, Peter Melchior
Spectral energy distribution (SED) modeling is one of the main methods to estimate galaxy properties, such as photometric redshifts, , and stellar masses, , for extragalact…
