Surface data imputation with stochastic processes
Arsalan Jawaid, Samuel Schmidt, Marvin Lotz +1
Spurious measurements frequently occur in surface data from technical components. Excluding or ignoring these spurious points may lead to incorrect surface characterization if thes…
Cosmic Shear Results from the Deep Lens Survey - II: Full Cosmological Parameter Constraints from Tomography
M. James Jee, J. Anthony Tyson, Stefan Hilbert +3
We present a tomographic cosmic shear study from the Deep Lens Survey (DLS), which, providing a limiting magnitude r_{lim}~27 (5 sigma), is designed as a pre-cursor Large Synoptic…
Characterizing and Propagating Modeling Uncertainties in Photometrically-Derived Redshift Distributions
Augusta Abrahamse, Lloyd Knox, Samuel Schmidt +3
The uncertainty in the redshift distributions of galaxies has a significant potential impact on the cosmological parameter values inferred from multi-band imaging surveys. The accu…
From Data to Software to Science with the Rubin Observatory LSST
Katelyn Breivik, Andrew J. Connolly, K. E. Saavik Ford +97
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) dataset will dramatically alter our understanding of the Universe, from the origins of the Solar System to the…
Discovery of a Dissociative Galaxy Cluster Merger with Large Physical Separation
William A. Dawson, David Wittman, Myungkook Jee +10
We present DLSCL J0916.2+2951 (z=0.53), a newly discovered major cluster merger in which the collisional cluster gas has become dissociated from the collisionless galaxies and dark…
Mapping the Galaxy Color-Redshift Relation: Optimal Photometric Redshift Calibration Strategies for Cosmology Surveys
Daniel Masters, Peter Capak, Daniel Stern +17
Calibrating the photometric redshifts of >10^9 galaxies for upcoming weak lensing cosmology experiments is a major challenge for the astrophysics community. The path to obtaining t…
