Scientists Piece Together the Largest U.S.-Based Dark Matter Experiment

July 22, 2019

Most of the remaining components needed to fully assemble an underground dark matter-search experiment called LUX-ZEPLIN (LZ) arrived at the project’s South Dakota home during a rush of deliveries in June. Once it is up and running, data captured by the detectors’ electronics will ultimately be transferred to NERSC, LZ’s primary data center, via ESnet. Read More »

Three Sky Surveys Completed in Preparation for Dark Energy Spectroscopic Instrument

July 9, 2019

It took three sky surveys – conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights – to prepare for a new project that will create the largest 3D map of the universe’s galaxies and glean new insights about the universe’s accelerating expansion.

Cleaning Cosmic Microwave Background Data to Measure Gravitational Lensing

June 6, 2019

Gravity from distant galaxies cause tiny distortions in cosmic microwave background temperature maps - a process called gravitational lensing - which are detected by data analysis software run on supercomputers like the Cori system at NERSC. Unfortunately, this temperature data is often corrupted by foreground emissions from extragalactic dust, gas, and other noise sources that are challenging to model. So Berkeley Lab researchers developed a statistical method for analyzing CMB data that is largely immune to the foreground noise effects. Read More »
