The Very Nearby Galaxies Survey - a Herschel key program -------------------------------------------------------- Proposal ID: KPGT_cwilso01_1 Title: "Physical Processes in the Interstellar Medium of Very Nearby Galaxies" Principal Investigator: Christine Wilson (McMaster University) Category: KPGT Summary: We propose to use the SPIRE and PACS instruments on Herschel to measure the emission spectrum from dust as well as important cooling lines from the gaseous interstellar medium in sample of 13 very nearby galaxies (M51, M81, NGC2403, NGC891, M83, M82, Arp220, NGC4038/39, NGC1068, NGC4151, CenA, NGC4125, and NGC205). These galaxies have been chosen to probe as wide a region in galaxy parameter space as possible while maximizing the achievable spatial resolution and are already well-studied from X-ray and optical through to radio wavelengths. The far-infrared and submillimeter wavelengths probed by Herschel are absolutely crucial for understanding the physical processes and properties of the interstellar medium,the interplay between star formation and the interstellar medium in galaxies, and how they may depend on the wider galaxian environment. VNGS Target Galaxies mapped with SPIRE photometer (all): Arp 220 Cen A M 81 M 82 M 83 NGC 1068 NGC 205 (also includes some outskirts of M31) NGC 2403 NGC 4038 ("the Antennae"; also includes NGC 4039) NGC 4125 NGC 4151 NGC 5194 (M51; also includes companion NGC 5195) NGC 891 Files summary: Naming convention: arp220-2C8F-PLWmap_MS-v51-Brigade.fits - 500 micron map arp220-2C8F-PMWmap_MS-v51-Brigade.fits - 350 micron map arp220-2C8F-PSWmap_MS-v51-Brigade.fits - 250 micron map Pixel sizes are 6, 8, 12" at 250, 350, and 500 microns, respectively Reference for data reduction: G. J. Bendo et al., 2012, MNRAS, 419, 1833 Additional Notes: Two sets of maps are included for Cen A, M81, and M82. M81 and M82 were SDP targets and so we provide both maps made with larger pixels that were used for the SDP publications (Bendo et al. 2010, Roussell et al. 2010) as well as the standard maps. M8[1,2]*largePix.fits - SDP reduction, pixel sizes 6, 10, 14" M8[1,2]*smallPix.fits - standard reduction, pixel sizes 6, 8, 12" Cen A has a variable central source and so was observed a second time with the SPIRE photometer at the same time as the SPIRE spectrometer observation. The second observation is shallower and smaller. cena-2C77-*.fits - deep map cena-66AC-*.fits - smaller, shallow map
