Modeling redshift uncertainties in Roman weak lensing cosmology
Journal article Journal of Cosmology and Astroparticle Physics · July 1, 2026 Cosmological constraints using weak gravitational lensing measurements from the Roman Space Telescope will require a powerful method for modelling uncertainties in the galaxy redshift distribution. In this work, we use an optimized version of the principal ... Full text CiteUniform Rolling: An LSST Observing Cadence Offering Sufficient Survey Uniformity for Comprehensive Cosmological Analysis
Journal article Astrophysical Journal Supplement Series · June 1, 2026 The Legacy Survey of Space and Time (LSST) that will be carried out by the NSF-DOE Vera C. Rubin Observatory promises to be the defining survey of the next decade for both static and time-domain science. Maximizing the LSST’s scientific output requires a n ...

Journal article Astrophysical Journal · May 1, 2026 A typical Bayesian inference on the values of some parameters of interest q from some data D involves running a Markov Chain (MC) to sample from the posterior (Formula presented) p(q,n∣D)∝L(D∣q,n)p(q)p(n), where n are some nuisance parameters with a separa ...
