A DECADE of Giants: A catalog of 42,000 optically identified galaxy clusters from 13,000 of the sky
D. Anbajagane, C. To, M. Gaido +44
Galaxy clusters are sensitive to a rich variety of physics spanning a wide dynamic range, from microphysical to cosmological scales. Optical datasets are efficient at identifying c…
Extending SOMPZ beyond Spectroscopic Coverage for Roman Weak Lensing
Yufei Zhen, Chun-Hao To, Boyan Yin +7
Precision weak lensing cosmology requires accurate galaxy redshift distributions. However, the spectroscopic samples used to characterize these distributions do not fully span the…
Combining Rubin and Roman photometry and its implications for photometric redshift estimation
Tae-hyeon Shin, Rachel Mandelbaum, Chun-Hao To +14
We perform a joint Roman--Rubin photometry analysis using the LSST Science Pipelines (LSP) on simulated images, by using the Roman F158 band as the reference band and applying forc…
A census of Dark Energy Survey Year 3 redMaPPer galaxy clusters in a high exposure eROSITA All Sky Survey region
P. A. Giles, A. K. Romer, J. Pilling +64
We present the cross-match of galaxy clusters detected by redMaPPer using the first three years of Dark Energy Survey (DESY3RM) operations, and the first release of the eROSITA-All…
Dark Energy Survey Year 6 Results: fast and interpretable posterior predictive checks for correlated cosmic probes
C. Doux, J. Muir, A. Ferté +59
We present a fast and numerically stable framework for conducting posterior predictive distribution (PPD) tests of internal consistency in correlated cosmological probes. Our metho…
PSFSim: PhySics First Simulations for the Point Spread Function of the Roman Space Telescope
Nihar Dalal, Chris Hirata, Charuhas Shiveshwarkar +6
We present a new tool for generating simulated point spread functions (PSFs) in the Wide Field Instrument (WFI) of the Nancy Grace Roman Space Telescope. The simulation tool is phy…
