Description
The Dark Energy Survey (DES) is in its fourth year of a five year observing program. We’re on our way to mapping 300 million galaxies and measuring 3000 type Ia supernovae for dark energy studies as well as monitoring 800 Active galaxies so we can use reverberation mapping to measure supermassive black hole masses across the last 12 billion years (to z~4). Over 525 nights DES combines a wide-field imaging survey with a narrower time-lapse survey. OzDES are following up the narrow region with 100 nights of spectroscopy on the Anglo-Australian Telescope. I’ll give an update of progress, give some early results, and show how we expect to use this data to constrain dark energy through type Ia supernovae, gravitational lensing, and Baryon Acoustic Oscillations.
