Projects
Our group participates in several international collaborations by contributing a broad range of expertise in observations, data analysis, survey planning, software development and theoretical interpretation. An overview the various projects that members of our group are involved in are published on these pages.
Dark Energy Survey
The Dark Energy Survey (DES) is a major new astronomical survey specifically designed to measure the expansion history of the universe to high precision, thus uncovering the nature of the dark energy which is driving this ever-accelerating expansion. Coming online in 2013 and utilizing 525 nights across 5 years, the survey will map over 5000 square degrees of the sky, detecting over 300 million galaxies.
DESI
The Dark Energy Spectroscopic Instrument (DESI) will measure the effect of dark energy on the expansion of the universe. It will obtain optical spectra for tens of millions of galaxies and quasars, constructing a 3-dimensional map spanning the nearby universe to 10 billion light years.
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio interferometer array project under construction in South Africa. As an official guest instrument on the Square Kilometre Array (SKA) South Africa site, HIRAX will map large-scale neutral hydrogen emission across the southern sky. The experiment aims to study the evolution of dark energy, investigate transient radio sources such as fast radio bursts and pulsars, and contribute to a range of cosmological studies through collaboration with other surveys.
LSST
The goal of the Large Synoptic Survey Telescope (LSST) project is to conduct a 10-year survey of the sky that will deliver a 200 petabyte set of images and data products that will address some of the most pressing questions about the structure and evolution of the universe and the objects in it.
PAU
The evidence for an accelerated expansion of the universe has created a crisis in our understanding of the universe and the fundamental laws of physics. PAUS will shed new light into the Physics of the Accelerating Universe by providing accurate and complete redshift characterization for millions of galaxies.
