An Overview of the LSST Image Processing Pipelines
James Bosch, Yusra AlSayyad, Robert Armstrong +31
The Large Synoptic Survey Telescope (LSST) is an ambitious astronomical survey with a similarly ambitious Data Management component. Data Management for LSST includes processing on…
Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
Chiaki Hikage, Masamune Oguri, Takashi Hamana +34
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137deg of the sky. Thanks to the high effect…
SCARLET: Source separation in multi-band images by Constrained Matrix Factorization
Peter Melchior, Fred Moolekamp, Maximilian Jerdee +4
We present the source separation framework SCARLET for multi-band images, which is based on a generalization of the Non-negative Matrix Factorization to alternative and several sim…
The Dark Energy Survey Image Processing Pipeline
E. Morganson, R. A. Gruendl, F. Menanteau +40
The Dark Energy Survey (DES) is a five-year optical imaging campaign with the goal of understanding the origin of cosmic acceleration. DES performs a 5000 square degree survey of t…
