J/AJ/143/16 HST photometry of IC 883 star clusters (Modica+, 2012) ================================================================================ Multi-wavelength GOALS observations of star formation and active galactic nucleus activity in the luminous infrared galaxy IC 883. Modica F., Vavilkin T., Evans A.S., Kim D.-C., Mazzarella J.M., Iwasawa K., Petric A., Howell J.H., Surace J.A., Armus L., Spoon H.W.W., Sanders D.B., Wong A., Barnes J.E. =2012AJ....143...16M ================================================================================ ADC_Keywords: Galaxies, IR ; Photometry, HST ; Associations, stellar Keywords: galaxies: active - galaxies: individual (IC 883) - galaxies: interactions Abstract: New optical Hubble Space Telescope (HST), Spitzer Space Telescope, Galaxy Evolution Explorer, and Chandra observations of the single-nucleus, Luminous InfraRed Galaxy (LIRG) merger IC 883 are presented. The galaxy is a member of the Great Observatories All-sky LIRG Survey (GOALS) and is of particular interest for a detailed examination of a luminous late-stage merger due to the richness of the optically visible star clusters and the extended nature of the nuclear X-ray, mid-IR, CO, and radio emission. In the HST Advanced Camera for Surveys images, the galaxy is shown to contain 156 optically visible star clusters distributed throughout the nuclear regions and tidal tails of the merger, with a majority of visible clusters residing in an arc ~3-7kpc from the position of the mid-infrared core of the galaxy. The luminosity functions of the clusters have an {alpha}_F435W_~-2.17 +/-0.22 and {alpha}_F814W_~-2.01+/-0.21, compared with V-band-derived values measured for the well-studied LIRG NGC 34 and the Antennae Galaxy of {alpha}~-1.7+/-0.1 and -2.13+/-0.07, respectively. Description: GOALS (Armus et al., 2009PASP..121..559A) is a multi-wavelength survey of a complete sample of LIRGs in the IRAS Revised Bright Galaxy Sample (RBGS; Sanders et al. 2003, Cat. J/AJ/126/1607). HST observations of IC 883 with the Wide Field Channel (WFC) of the Advanced Camera for Surveys (ACS) were obtained on 2006 January 11 as part of a much larger campaign (HST-GOALS; A. S. Evans et al. 2012, in preparation). The galaxy was imaged with the F435W and F814W filters.
