The LSST Science Pipelines Software: Optical Survey Pipeline Reduction and Analysis Environment
Rubin Observatory Science Pipelines Developers, Yusra AlSayyad, Robert Armstrong +83
The NSF-DOE Vera C. Rubin Observatory is executing the Legacy Survey of Space and Time (LSST) as its prime mission, producing a series of data releases over the ten-year survey. Th…
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…
The Vera C. Rubin Observatory Data Preview 1
Vera C Rubin Observatory Team, Tatiana Acero Cuellar, Emily Acosta +325
We present Rubin Data Preview 1 DP1, the first data from the NSF DOE Vera C Rubin Observatory, comprising raw and calibrated single epoch images, coadds, difference images, detecti…
Opportunities in AI/ML for the Rubin LSST Dark Energy Science Collaboration
LSST Dark Energy Science Collaboration, Eric Aubourg, Camille Avestruz +63
The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will produce unprecedented volumes of heterogeneous astronomical data (images, catalogs, and alerts) that cha…
Photometric Redshift Estimation for Rubin Observatory Data Preview 1 with Redshift Assessment Infrastructure Layers (RAIL)
T. Zhang, E. Charles, J. F. Crenshaw +87
We present the first systematic analysis of photometric redshifts (photo-z) estimated from the Rubin Observatory Data Preview 1 (DP1) data taken with the Legacy Survey of Space and…
Variability-finding in Rubin Data Preview 1 with LSDB
Konstantin Malanchev, Melissa DeLucchi, Neven Caplar +56
The Vera C. Rubin Observatory recently released Data Preview 1 (DP1) in advance of the upcoming Legacy Survey of Space and Time (LSST), which will enable boundless discoveries in t…
Initial Characterization of Stellar Photometry of Roman images from the OpenUniverse Simulations
Lauren Aldoroty, Daniel Scolnic, Arun Kannawadi +4
NASA's Nancy Grace Roman Space Telescope (Roman) will provide an opportunity to study dark energy with unprecedented precision and accuracy using several techniques, including meas…
Redshift Assessment Infrastructure Layers (RAIL): Rubin-era photometric redshift stress-testing and at-scale production
The RAIL Team, Jan Luca van den Busch, Eric Charles +31
Virtually all extragalactic use cases of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) require the use of galaxy redshift information, yet the vast majorit…
PSFs of coadded images
Rachel Mandelbaum, Mike Jarvis, Robert H. Lupton +5
We provide a detailed exploration of the connection between choice of coaddition schemes and the point-spread function (PSF) of the resulting coadded images. In particular, we inve…
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…
Faro: A framework for measuring the scientific performance of petascale Rubin Observatory data products
Leanne P. Guy, Keith Bechtol, Jeffrey L. Carlin +14
The Vera C. Rubin Observatory will advance many areas of astronomy over the next decade with its unique wide-fast-deep multi-color imaging survey, the Legacy Survey of Space and Ti…
Impact of Point Spread Function Higher Moments Error on Weak Gravitational Lensing
Tianqing Zhang, Rachel Mandelbaum, The LSST Dark Energy Science Collaboration
Weak gravitational lensing is one of the most powerful tools for cosmology, while subject to challenges in quantifying subtle systematic biases. The Point Spread Function (PSF) can…
Mitigating the effects of undersampling in weak lensing shear estimation with metacalibration
Arun Kannawadi, Erik Rosenberg, Henk Hoekstra
Metacalibration is a state-of-the-art technique for measuring weak gravitational lensing shear from well-sampled galaxy images. We investigate the accuracy of shear measured with m…
The effect of detector nonlinearity on WFIRST PSF profiles for weak gravitational lensing measurements
Andrés. A. Plazas, Charles A. Shapiro, Arun Kannawadi +3
Weak gravitational lensing (WL) is one of the most powerful techniques to learn about the dark sector of the universe. To extract the WL signal from astronomical observations, gala…
The Impact of Interpixel Capacitance in CMOS Detectors on PSF shapes and Implications for WFIRST
Arun Kannawadi, Charles A. Shapiro, Rachel Mandelbaum +3
Unlike optical CCDs, near-infrared detectors, which are based on CMOS hybrid readout technology, typically suffer from electrical crosstalk between the pixels. The interpixel capac…
