2 Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013 “Virtual Astronomy” … is the utilization of diverse, distributed, multi-wavelength data resources and distributed storage and computational services to enable both novel and more efficient research in astronomy Re-use and re-purpose data; broaden impact of data taken at significant expense Support research in the world of TB  PB scale data collections “data enabled discovery – the database is the new laboratory” (T. Tyson) Enabling virtual astronomy: the Virtual Observatory Observation Theory Simulation Data 2

18 Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013 VO Impact and Penetration Astronomers use VO every day without realizing it A few examples  Major archives and data centers are VO compliant  Hubble Legacy Archive is built with “VO Inside”  HEASARC Xamin facility  Dark Energy Survey pipeline and archive  WIYN One-Degree Imager pipeline and archive  PanSTARRS  LSST development ~500k VO-compliant service requests every week at VAO organizations 18

19 Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013 VO-Enabled Science Citation analysis done by M. Kurtz (ADS) finds nearly 2,500 VO-related papers 19

21 Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013 VO-Enabled Science Citation analysis done by M. Kurtz (ADS) finds nearly 2,500 VO-related papers  Certainly some “contamination” in this sample, and it would take significant manual effort to clean the list Recent VO-enabled research papers  “The Chandra Multi-wavelength Project: Optical Spectroscopy and the Broadband Spectral Energy Distributions of X-ray Selected AGNs,” M. Trichas et al., ApJS 200, 2, 17 (2012)  “The Halo Masses and Galaxy Environments of Hyperluminous QSOs at z~=2.7 in the Keck Baryonic Structure Survey,” R. Trainor and C.

24 Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013 Programmatic Matters NVO: 2001-2008, NSF funded with some NASA in-kind support VAO: 2010-2014, NSF (~2/3) and NASA (~1/3) funded; established VAO, LLC with 50-50 interest from AUI and AURA October 2012: NSF/NASA asked VAO to finish work by end of September 2014  “VAO and its NVO predecessor have provided an essential foundation on which a future virtual observatory can be maintained…the successful protocols and standards that will be an important resource for our scientific community”  “document and package all existing products, middleware, protocols, tools, and other results, so as to be of the greatest use to any successor activity” 24

25 Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013 VAO Project Summary Infrastructure activities are well underway and within scope for the remaining funding Data-cube initiative has international support Maintain operations support Applications will be packaged and made publicly available for re-use and adaptation by others, as will all infrastructure components Successor organization TBD 25

26 Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013Robert Hanisch, Radio Astronomy / LSST, Charlottesville8 May 2013 Looking Ahead Virtual astronomy is part of the research environment of today and the future VAO/IVOA infrastructure is the backbone for data discovery, access, and interoperability Maintain through community / data center take-up  Major observatories and data centers, large projects, scholarly publications  Use of standards and sharing of software, experience, and best practices improves the research environment and reduces development costs http://usvao.org/ 26
