Starting in the early 2020s, the Large Synoptic Survey Telescope will carry out a decade long survey of the southern sky. Offering a unique combination of breadth, depth and cadence, this survey will enable us to address some of the most profound questions in modern astronomy.
It will also present huge challenges: how can we collect, store, process and — most importantly! — understand the hundreds of petabytes of data which will be produced? How can we combine the statistical and algorithmic rigor needed to enable the next generation of precision cosmology with the speed and agility needed to identify and respond to transients and variable sources? How can we make vast volumes of data available to the community in a way that enables your particular science
In this talk, I will briefly review the design and scientific goals of LSST, provide an update on the current status of construction, explore some of the algorithmic and data processing challenges that the LSST Data Management team faces, and describe the key role that members of the Department of Astronomy here at UW are playing in making it all possible.
Where: B305 Conference Room, Physics-Astronomy Building
Stephen Portillo will be discussing “Improved Source Detection in Crowded Fields using Probabilistic Cataloging”, based on his work on probabilisitic cataloging described in arXiv:1703.01303.
DIRAC director Andy Connolly attended the FIRE (Future in Review) Conference in Park City, Utah in the middle of October. FIRE has been described as “The best technology conference in the world.” (The Economist) and is the brain child of Mark Anderson (one of DIRAC’s board members).
The conference lived up to its billing and was a mix of talks and discussions on topics as wide ranging as, how the retina works, protecting intellectual property, and the loss of coral due to the warming of the seas. Andy described how by taking the data and images from telescopes such as the LSST and looking at it in new ways we can find for asteroids and transient sources.
On October 4-5, 2017, DIRAC Institute hosted the first ADAM HackDays with the B612 Foundation’s Asteroid Institute.
ADAM (Asteroid Decision and Analysis Machine) is a project led by the Asteroid Institute, aiming to better understand threats and opportunities coming from asteroids in the Solar System. ADAM will be a cloud-based system for large-scale precise integration and analysis of trajectories of asteroids, especially those that are potentially hazardous to Earth.
The HackDays brought together DIRAC researchers, Asteroid Institute Fellows, and community supporters for a first ADAM team meeting and two days of hacking on ADAM code.
The DIRAC Institute is a world leading, interdisciplinary research center that addresses fundamental questions about the origins and evolution of our universe.
Our research brings together scientists across many disciplines on a mission to understand the nature of Dark Matter and Dark Energy, the emergence of structure within the universe, the formation of galaxies, the birth and evolution of black holes, the transformations of stars, and the origins of the planets.
