Analyzing interferometric observations of strong gravitational lenses with recurrent and convolutional neural networks
Warren R. Morningstar, Yashar D. Hezaveh, Laurence Perreault Levasseur +4
We use convolutional neural networks (CNNs) and recurrent neural networks (RNNs) to estimate the parameters of strong gravitational lenses from interferometric observations. We exp…
Overview of the Dark Energy Spectroscopic Instrument
Paul Martini, Stephen Bailey, Robert W. Besuner +23
The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of the Universe using the Baryon Acoustic Oscillation technique. The spectra…
Approximating photo- PDFs for large surveys
A. I. Malz, P. J. Marshall, S. J. Schmidt +3
Modern galaxy surveys produce redshift probability density functions (PDFs) in addition to traditional photometric redshift (photo-) point estimates. However, the storage of pho…
Overview of the DESI Legacy Imaging Surveys
Arjun Dey, David J. Schlegel, Dustin Lang +157
The DESI Legacy Imaging Surveys are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Surve…
ATLAS Probe: Breakthrough Science of Galaxy Evolution, Cosmology, Milky Way, and the Solar System
Yun Wang, Massimo Robberto, Mark Dickinson +37
ATLAS (Astrophysics Telescope for Large Area Spectroscopy) Probe is a concept for a NASA probe-class space mission. It is the follow-up space mission to WFIRST, boosting its scient…
The Dark Energy Survey Data Release 1
T. M. C. Abbott, F. B. Abdalla, S. Allam +199
We describe the first public data release of the Dark Energy Survey, DES DR1, consisting of reduced single epoch images, coadded images, coadded source catalogs, and associated pro…
