Joint Observations with Space Telescopes


Joint Observations with Space Telescopes

The following opportunities are available to combine observations with the VLBA and several space observatories operating at very different wavelengths.  (Joint observations combining the VLBA with other ground-based VLBI instruments are embedded in the periodic VLBA Call for Proposals, and described in the VLBA Observational Status Summary.)  The following joint observation opportunities with the LBO will continue in semester 2017B via existing arrangements.

Joint Observations with Chandra X-ray Observatory

In previous semesters, the community has had the opportunity to propose for observing time on NRAO facilities through a joint program with the Chandra X-ray Observatory.  Beginning in semester 2016A, proposers to the NRAO have had the opportunity to request time on Chandra, to be awarded on the recommendation of the Telescope Allocation Committee (TAC) and approved by the Director.  This arrangement now applies to facilities of the LBO.  Up to 120 ksec total will be made available for NRAO, LBO, and GBO proposals annually.  See the Joint Observations with Chandra page for details.

Joint Observations with the Hubble Space Telescope (HST)

By agreement between the NRAO and the Space Telescope Science Institute, STScI will be able to award up to 3% of the available time on the VLBA, VLA, and GBT to highly ranked proposals that request time on those telescopes and on HST.  In return, STScI has offered 30 orbits of HST time for allocation by the NRAO, LBO, and GBO TACs to proposals submitted for observing semesters 2017B and 2018A.   See the Joint Observations with HST page for details.

Joint Observations with Swift Gamma-Ray Burst Mission

To foster correlative observations, a joint Swift/NRAO observing program has been established, detailed in a Memorandum of Understanding. By this agreement, the Swift Program permits the NRAO, LBO, and GBO to award up to 300 kiloseconds of Swift observing time per year.   Similarly, the Swift Guest Investigator (GI) Program may award observing time on the VLBA, VLA, and GBT.  See the Joint Observations with Swift page for details.

Joint Observations with Fermi Gamma-Ray Space Telescope

We remind the community that it is possible to propose for observing time on LBO facilities through the Fermi Gamma-ray Space Telescope Joint Proposal Opportunity or the Cooperative Proposal Opportunity.  See the Joint Observations with Fermi page for details.

Connect with NRAO

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
