"The SIRTF Nearby Galaxies Survey (SINGS):
Physics of the Star-Forming ISM and Galaxy Evolution"

A comprehensive imaging and spectroscopic survey of 75 nearby galaxies in order to characterize their large-scale infrared properties. The primary science goals are to understand the physical processes connecting star formation to the ISM and to provide diagnostic templates for interpreting observations of objects in the distant universe.

Principal Investigator: Robert Kennicutt Jr. (University of Arizona)

Total Observatory Time: 512 hours

Co-Investigators include:
Lee Armus (SIRTF Science Center, California Institute of Technology), Daniela Calzetti (Space Telescope Science Institute), Daniel Dale (California Institute of Technology), Bruce Draine (Princeton University), Chad Engelbracht (University of Arizona), Karl Gordon (University of Arizona), George Helou (SIRTF Science Center/IPAC, California Institute of Technology), David Hollenbach (NASA - Ames Research Center), Claus Leitherer (Space Telescope Science Institute), Sangeeta Malhotra (Johns Hopkins University), Michael Regan (Space Telescope Science Institute), George Rieke (University of Arizona), Marcia Rieke (University of Arizona), Michele Thornley (National Radio Astronomy Observatory & Bucknell University)

Short Abstract

This project will use 512 hours of SIRTF observing time to conduct a comprehensive Legacy Science survey to characterize the infrared emission across the entire range of galaxy properties and star formation environments, including regions that until now have been inaccessible at infrared wavelengths. SINGS will provide:

  • New insights into the physical processes connecting star formation to the ISM properties of galaxies;
  • A vital foundation of data, diagnostic tools, and astrophysical inputs for understanding SIRTF observations of the distant universe and ultraluminous and active galaxies; and
  • An archive that integrates visible/UV and IR/submillimeter studies into a coherent self-consistent whole, and enables many follow-up investigations of star formation and the ISM.

SINGS will characterize the large-scale infrared properties of galaxies and their principal infrared-emitting components through SIRTF imaging and low-resolution spectroscopy of 75 nearby galaxies (d < 30 Mpc), and targeted high-resolution spectroscopy of their centers and a representative set of extranuclear IR-emitting regions in the galaxies. These data will be combined with an extensive library of ground- and space-based data at other wavelengths.
