GOALS

The Great Observatories All-sky LIRG Survey (GOALS), is combining imaging and spectroscopic data from NASA's Spitzer, Hubble, Chandra and GALEX space-borne observatories in a comprehensive study of over 200 of the most luminous infrared-selected galaxies in the local Universe. The sample consists of approximately 180 Luminous Infrared Galaxies (LIRGs), which are systems with total infrared emission brighter than 1011 L and less than 1012 L, as well as over 20 Ultra-Luminous Infrared Galaxies (ULIRGs) with luminosity of 1012 L or greater. The objects are a complete subset of the IRAS Revised Bright Galaxy Sample (RBGS), which comprises 629 extragalactic objects with 60-micron flux densities above 5.24 Jy and Galactic latitude above five degrees. The RBGS objects, all with redshifts, z < 0.088, are the brightest 60-micron sources in the extragalactic sky. The LIRGs and ULIRGs targeted in GOALS span the full range of nuclear spectral types (type-1 and type-2 AGN, LINERs, and starbursts) and interaction stages (major mergers, minor mergers, and isolated galaxies). They provide an unbiased picture of the processes responsible for enhanced infrared emission in the local Universe, and are excellent analogs for comparisons with infrared and sub-millimeter selected galaxies at high-redshift.


GOALS News:
  • The GOALS team was awarded a JWST ERS program to obtain MIRI, NIRCAM and NIRSPEC images and spectra of a sample of local LIRGs selected from the GOALS sample. The title of this program is "A JWST Study of the Starburst-AGN Connection in Merging LIRGs." A link to the abstracts of the awarded ERS programs can be found here. More information about the GOALS ERS program will be posted here soon!

  • Kirsten Larson was awarded HST Cycle-25 time for the proposal "Clumpy Star Formation in Local LIRGS" to obtain narrow-band P-beta imaging of 20 GOALS galaxies.
  • Tanio Diaz-Santos was awarded ALMA Cycle-5 time for the proposal "Tracking the Properties of Gas Clumps in Luminous Infrared Galaxies Along the Complete Merger Sequence." to obtain CO(2-1) emmission line observations of 14 GOALS galaxies.
  • Jason Chu's paper presents the GOALS Herschel image atlas and aperture photometry (2017 ApJS, 229,25). PRESS Release.
  • Loreto Barcos-Muñoz's paper uses 33 GHz radio continuum observations from the Very Large Array to estimate the size of the energetically dominant regions in 22 LIRGS (2017 ApJ, 843,117).
  • Tanio Diaz-Santos's paper presents the GOALS Herschel/PACS line emission survey (2017 ApJ, 846, 32). The line fluxes and AGN fractions of the sample are available here.
