School of Physics Colloquia Series - Cosmology with the Dark Energy Survey
The Dark Energy Survey, and its Australian arm "OzDES", are in the final year of a 6-year observing campaign with aim of measuring the properties of dark energy through diverse phenomena including weak lensing, baryon acoustic oscillations, cluster cosmology, and type Ia supernovae. After imaging 5000 square degrees of the southern sky we expect our final catalogue to include
300 million galaxies, and after following-up 30 square degrees with time-lapse spectroscopy we will have discovered over 3000 supernovae. In addition we are monitoring 771 Active Galactic Nuclei out to redshift z~4 to measure the evolution of supermassive black hole mass over the last 12 billion years. I will give an update of the most exciting results so far, outline the ongoing analyses, and summarise the wealth of data already available for use by the whole community.
