  1. VNGS science highlight: PDR models of M51 [CII]/[OI]63 Similar gas properties in arm and interarm regions. ([CII]+[OI]63)/FTIR Higher densities and stronger radiation fields in center T. Parkin et al., 2013, ApJ

  2. Priorities for future work • Continue analysis of FTS data • M83: Wu et al. 2014 (referee report received) • M51: (Schirm et al., analysis underway) • Other galaxies: Cen A, NGC 891 • Continue analysis of PACS spectroscopy • NGC 891 (Hughes et al., first draft circulated) • Other galaxies: NGC 5195, M81, NGC 2403, M83 (outer strip only) • Overview/cross-galaxy comparison paper(s)? Dust? Gas? Combined? • Note: not clear who will work on remaining data …

  3. VNGS Publications since June, 2013 • T. Parkin et al., 2014, “The physical characteristics of the gas in the disk of Centaurus A using the Herschel Space Observatory”, ApJ, in press • T. Hughes et al., “A resolved analysis of cold dust and gas in the nearby edge-on spiral NGC 891”, 2014, A&A • M. Schirm et al., “Herschel-SPIRE Fourier Transform Spectrometer Observations of Excited CO and [C I] in the Antennae (NGC 4038/39): Warm and Cold Molecular Gas”, 2014, ApJ • C. Wilson et al., “Cold Dust but Warm Gas in the Unusual Elliptical Galaxy NGC 4125”, 2013, ApJ • T. Parkin et al., “Regional Variations in the Dense Gas Heating and Cooling in M51 from Herschel Far-infrared Spectroscopy”, 2013, ApJ • K. Foyle et al., “Star formation and dust heating in the FIR bright sources of M83”, 2013, MNRAS

  4. Other plans and analysis techniques • PACS spectroscopy cubes fully processed and ready to submit to the Herschel archive • Foyle et al. (2013) paper on M83 applied getsources to an extragalactic source (see also Natale, Foyle et al. 2014 for M33) • Analysis of FTS intermediate sampled maps underway using source-correction tool from Wu et al. (2013) in hipe • Last data delivery will be FTS spectroscopy • Need to think about what products it makes sense to deliver beyond the basic processed hipe data
