Abstract

The Very Large Array (VLA) Sky Survey (VLASS) is a new all-sky radio survey that is currently being developed at the National Radio Astronomy Observatory (NRAO). VLASS will cover the entire sky that is visible to the VLA (decl. > -40°) over three observing epochs with a frequency coverage of 2–4 GHz and angular resolution of $\sim$2.5 arcsec. We expect to reach rms $\sim$120 microJy per epoch, with rms of $\sim$70 microJy when the three epochs are combined. Observations are being taken in full polarization. The data products will include full-continuum images, spectral-index and polarization image cubes, and source catalogs. Scientific applications include the study of radio transients, Faraday tomography of radio galaxies, and demographics of the radio loud/intermediate radio-galaxy population.
