By agreement with NRAO, proposers interested in making use of the NRAO Very Large Array (VLA), Very Long Baseline Array (VLBA) and/or Green Bank Telescope (GBT) facilities as part of their Chandra science may submit a single proposal in response to this CfP. The award of NRAO time will be made to highly ranked Chandra proposals and will be subject to approval by the NRAO Director.
The primary criterion for the award of NRAO time is that both Chandra and NRAO datasets are essential to meet the scientific objectives of the proposal. No NRAO time will be allocated without Chandra time.
NRAO plans to make up to 3% of VLA, VLBA, and GBT observing time available for this opportunity with a maximum of 5% in any configuration/time period and including an 18-month period close to the Chandra Cycle 9 such that all VLA configurations are available.
Proposers wishing to make use of this opportunity must provide the following additional NRAO-related information as part of their Chandra proposal:
- Indicate the choice of NRAO telescope(s) (VLA, VLBA, and/or GBT );
- For the VLA, indicate the requested configuration(s). Because of the Expanded VLA construction project, the future schedule for moving antennas into the different VLA configurations is still uncertain, so the predictions of configuration dates given at http://www.vla.nrao.edu/genpub/configs/ should be regarded as tentative;
- For the VLA or VLBA enter the total estimated observing time and the observing wavelength(s) for each telescope/configuration;
- For the GBT enter the observing frequencies, choice of back end and frequency resolution requirements for spectral line observations. ; and
- Include in your scientific justification a full and comprehensive scientific and technical justification for the requested NRAO observing time.
Be aware that some Chandra targets might not require new NRAO observations because the joint science goals can be met using:
Demonstration of the technical feasibility of the proposed NRAO observations is the responsibility of the proposer, and must include image sensitivity and fidelity needs. The technical feasibility will be reviewed by NRAO before the proposal is evaluated. Detailed technical information concerning the VLA,VLBA, and the GBT can be found at http://www.vla.nrao.edu/astro/ (VLA), at http://www.vlba.nrao.edu/astro/ (VLBA) and at http://www.gb.nrao.edu/astronomers.shtml (GBT) . In particular, note the comprehensive 'Observational Status Summary' for the VLA and VLBA instruments , posted at http://www.vla.nrao.edu/astro/guides/vlas/current/ (VLA) and at http://www.vlba.nrao.edu/astro/obstatus/current/obssum.html (VLBA). The GBT proposers guide is available at http://www.gb.nrao.edu/gbtprops/man/GBTpg/GBTpg_tf.html .
If approved for NRAO time, successful PIs will be contacted by the VLA/VLBA Scheduling Officers (schedsoc@nrao.edu) once scheduling details are known. The successful PIs will then be responsible for submitting VLA and/or VLBA observing scripts to analysts@nrao.edu (VLA) and/or to vlbiobs@nrao.edu (VLBA) respectively . The deadline for the receipt of these scripts will be communicated by the VLA/VLBA Scheduling Officers. NRAO will perform final feasibility checks on these scripts and reserves the right to reject any observation determined to be infeasible for any reason. Such a rejection could jeopardize the success of the joint science program. In the case of the GBT, the successful observers will be responsible for carrying out the observations at the GBT (remote observing is possible for experienced GBT observers) and for preparing observing scripts in advance of the observations.
