The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) began in August 2017, with the intention of creating a survey which is by no means a complete survey of southern Seyfert, LINERs and other active galaxies but rather, offers a reasonably representative sample of radio-detected AGN in the nearby universe. The S7 uses the Wide Field Spectrograph (WiFeS) mounted on the ANU 2.3m telescope located at the Siding Spring Observatory to deliver an integral field of 38×25 arcsec at a spectral resolution of R = 7000 in the red (530−710nm), and R = 3000 in the blue (340 − 560nm).

DR 2

The full and final S7 data release, DR2, is now available. This data release includes all data cubes, nuclear spectra, and 2D emission-line fitting products for the full S7 sample of 131 galaxies. Documentation for this release can be found at: S7 Data Release 2. DR2 is fully described in Thomas et al. 2017.

Data Access

  • IFS data cubes and all 2D data products can be accessed through the Downloads page. Please see the "How do I" instructions on the right-hand side of the page for an easy guide on how to download the data.
  • Catalogue data can be obtained through the DataCentral's Query Service. Examples for simple SQL or ADQL queries are given on the right-hand side of the page
  • With the Single-Object-Viewer (SOV), you can inspect all S7 DR2 products for each individual source in DR2.
  • The Schema Browser is there to help you find specific data products.

The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) is an integral field spectroscopy survey targeting ~140 nearby galaxies. The S7 contains both the largest sample of active galaxies and the highest spectral resolution of any comparable integral field survey to date.
