AAS 242 Albuquerque
Splinter Session

An Explorer's Guide to the VLA Sky Survey (VLASS)

The VLA Sky Survey (VLASS) is a radio astronomical survey with the Very Large Array (VLA) from 2-4 GHz with ~2.5” resolution covering the sky from Declination -40 degrees and above. Observations for the survey commenced in 2017, with two full epochs completed and a third currently underway (with scheduled completion in 2024). The VLASS data and science ready data products are publicly available from the NRAO Archive. In this Splinter Session, we will describe the VLASS and some of the science highlights to emerge from the survey, and the suite of Data Products that enable this science. There will be a particular focus on using our new Single-Epoch continuum images and cubes for polarimetry and other applications. We will explore the survey itself and provide example uses of VLASS in conjunction with other available multi-wavelength astronomical surveys. We will guide users through the process of downloading and performing custom imaging of survey data for cases not covered by our data products. We will highlight community created tools that enhance the use of VLASS, and opportunities for further community based development for the survey. Information on other VLA surveys commensal with VLASS (VCSS, COSMIC, and realfast) will be presented. We will also report on current status of the VLASS and plans for the delivery of the remainder of the survey and its products.

The format of this session will include basic project overview talks, science presentations, demonstrations, and tutorials, with ample time for interaction and discussion. We especially encourage students and educators to attend, with presentations geared towards users coming from these perspectives and wanting to learn about the VLASS and potentially participate in VLASS-related science and outreach activities.

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.
