Image products will include the full-field PACS images at 70, 100, and 160 micron, and SPIRE images at 250, 350, and 500 micron, both at native resolution, and aligned, trimmed, and resampled to the same field-of-view and pixel size. Ancillary imaging (see below) will be aligned, matched and resampled to the Herschel images as well, and delivered as data products.
Our map sizes are designed to probe cool dust, if present, beyond the optical disk and to provide sufficient sky coverage to remove instrumental artifacts: we will thus map all galaxies to 1.5 times the optical radius with SPIRE. At the SPIRE wavelengths the depth of our imaging will be limited by confusion even for modest exposure times. At the shortest PACS wavelengths we cannot reach the confusion limit in reasonable exposure times, so we have chosen instead to obtain sufficient depth to detect the diffuse disk emission within 80-90% of the optical radius, and to detect IR sources with high S/N beyond that value. Our PACS maps, with sizes 1.2 times Dopt , are tailored to explore compact sources in the galaxies with Herschel's superior angular resolution. We adopt minimum map sizes of 10 x 10 arcmin2
Data are now all available and reduced:
- You can download the Kingfish PACS and SPIRE image atlas at the bottom of this page.
- You can access to the reduced PACS and SPIRE maps and to the User's Guide here.
The KINGFISH galaxies in the Hubble Tuning Fork.
Blue: Spitzer/MIPS 24 micron. Green: Herschel/PACS 100 micron. Red: Herschel/SPIRE 250 micron
We will target: (1) 55 nuclei; (2) 50 extra-nuclear regions in 16 targets, chosen to span a broad range of HII region properties; and (3) 148 radial strip positions in 33 galaxies, covering a wide range in IR surface brightness, and matched to the positions of existing 14-40 micron SINGS radial strip low-resolution spectral maps. Those maps maps are ~1 arcmin wide and extend past the IR-emitting radius. High-resolution 10-38 micron data are also available in all nuclear and extranuclear targets.
NGC 6946 observed with Spitzer at 8 μm. PACS spectroscopic fields are overlaid
in green. Spitzer IRS spectroscopic fields from SINGS are indicated:
5–14 μm low resolution spectral maps (red); 14–38 μm low resolution maps (magenta)
and 10–37 μm high-resolution spectral maps (cyan and blue).
The final KINGFISH spectroscopic data products are fully calibrated, PSF-reconstructed, astrometrically referenced stitched maps in all 5 target lines ([OI]63 micron, [OIII]88 micron, [NII]122 micron, [CII]158 micron, and [NII]205 micron) . The PACS spectroscopy line images will be formatted to be directly comparable to the Herschel broadband and SINGS images.
Line maps of [CII], [OIII], the two [NII] lines, and [OI] from KINGFISH observations
of NGC3521. The line maps are overlaid on the SINGS MIPS 24 μm image, and
clipped at an RMS level of 3-sigma. The top left panel shows radial velocities as measured from
the [CII] line (color and contours), while the other panels show line flux, in units given by
the respective color bars.
