redmonster performs automated redshift measurement, physical‑parameter estimation, and spectral classification of 1D astronomical spectra. This set of Python utilities outputs the best‑fit model, redshift, classification, and derived parameters in standard formats for downstream analysis. The repository includes templates, configuration files, and documentation to enable flexible redshift and parameter estimation workflows.

provabgs infers full posterior distributions of galaxy properties for galaxies in the DESI Bright Galaxy Survey using state-of-the-art Bayesian spectral energy distribution (SED) modeling of DESI spectroscopy and photometry. provabgs includes a state-of-the-art stellar population synthesis (SPS) model based on non-parametric prescription for star formation history, a metallicity history that varies over the age of the galaxy, and a flexible dust prescription. It has a neural network emulator for the SPS model that enables accelerated inference. Full posteriors of the 12 SPS parameters can be derived in ~10 minutes. The emulator is currently designed for galaxies from 0 < z < 0.6. provabgs also includes a Bayesian inference pipeline that is based on zeus (ascl:2008.010).
