Core Cosmology Library: Precision Cosmological Predictions for LSST

David Atienza Alonso, Jonathan Andrew Blazek

The Core Cosmology Library (CCL) provides routines to compute basic cosmological observables to a high degree of accuracy, which have been verified with an extensive suite of validation tests. Predictions are provided for many cosmological quantities, incl ...

LSST: From Science Drivers to Reference Design and Anticipated Data Products

David Atienza Alonso, Darong Huang, Jonathan Andrew Blazek, Shahram Khazaei, Anja Annemone Becker, Shikhar Tuli, Michelle Miller, Guillaume Blanc, Abhijit Saha, Wei Cui

We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the solar system, ex ...

Detecting galaxy-filament alignments in the Sloan Digital Sky Survey III

Jonathan Andrew Blazek, Yuguang Chen

Previous studies have shown the filamentary structures in the cosmic web influence the alignments of nearby galaxies. We study this effect in the LOWZ sample of the Sloan Digital Sky Survey using the 'Cosmic Web Reconstruction' filament catalogue. We find ...

The Dark Energy Survey: Data Release 1

Eduardo Sanchez, Xin Chen, Vanda Carla Costa Grisel, Aaron James Rossini, Yi Zhang, Jonathan Andrew Blazek, Jennifer Kaitlyn Olsen, Xi Chen, Augusto Martins Lima, Juan Andrei Villarroel Fernandez

We describe the first public data release of the Dark Energy Survey, DES DR1, consisting of reduced single-epoch images, co-added images, co-added source catalogs, and associated products and services assembled over the first 3 yr of DES science operations ...
