Alleviating prior dependencies for DESI DR1 clustering fits through reparameterization
Marco Bonici, Simone Paradiso, Glenn McGee +48
Bayesian analyses of the full-shape clustering of Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) exhibit prior-volume projection effects, whereby weakly constrain…

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…

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…
