报告摘要/Abstract
The Vera C. Rubin Observatory, hosting an 8 m-class optical survey telescope, is currently under construction in Chile. During the first 10 years of its operations, the Rubin Observatory will conduct the Legacy Survey of Space and Time (LSST) and provide the widest, fastest and deepest views of the (southern) night sky ever observed. In essence, the survey will cover the entire visible sky every three days, thus allowing unprecedented science of the variable and transient universe. With 189 CCDs, the Vera Rubin Observatory’s 3.2 gigapixel camera, with its large field of view (9.6 sq. deg.), offers a step change in the scientific questions we will be able tackle. From solar system science to the structure and composition of the Milky Way and the nature of dark energy, time-domain astrophysics will never look the same. However, with the expected flurry of new data come serious challenges in data management, data transportation and data reduction to allow scientists to make the most of the 10 million ‘alerts’ expected to be triggered each night, and the overall data volume of 515 PB that will be accumulated over the LSSTs 10-year lifetime. I will provide an update of the latest developments facilitating first light, currently foreseen for August 2024. I will also discuss both the exciting opportunities this new facility will offer in a truly unique parameter space, but also address the significant engineering and data science challenges we still have to overcome to facilitate breakthrough science.
报告人介绍/Bio:
Richard de Grijs obtained his PhD from the University of Groningen (Netherlands) in 1997, and subsequently held two postdoctoral positions (at the University of Virginia, USA, and the Institute of Astronomy, University of Cambridge, UK), before being appointed to a permanent post at the University of Sheffield (UK) in 2003. He joined the Kavli Institute for Astronomy and Astrophysics at Peking University in September 2009 as a full professor, where he actively contributed to the Institutes development (until February 2018). Since March 2018, he has been a Professor of Astrophysics and Associate Dean (Global Engagement) at Macquarie University in Sydney, Australia. Since July, 2023 The Board of Trustees of the International Space Science Institute in Beijing (ISSI-BJ) has elected Professor Richard de Grijs to head the Institute as its Executive Director.
