The KINGFISH project (Key Insights on Nearby Galaxies: a Far-Infrared Survey with Herschel)is an imaging and spectroscopic survey of 61 nearby (d<30 Mpc) galaxies, chosen to cover a wide range of galaxy properties and local interstellar medium (ISM) environments found in the nearby universe. Its broad goals are to characterize the ISM of present-day galaxies, the heating and cooling of their gaseous and dust components, and to better understand the physical processes linking star formation and the ISM. KINGFISH is a direct descendant of the Spitzer Infrared Nearby Galaxies Survey (SINGS), which produced complete Spitzer imaging and spectroscopic mapping and a comprehensive set of multiwavelength ancillary observations for the sample. The Herschel imaging consists of complete maps for the galaxies at 70, 100, 160, 250, 350, and 500 μm. The spectral line imaging of the principal atomic ISM cooling lines ([O I]63μm, [O III]88μm, [N II] 122,205 μm, and [C II] 158 μm) covers the subregions in the centers and disks that already have been mapped in the mid-infrared with Spitzer. The KINGFISH and SINGS multiwavelength data sets combined provide panchromatic mapping of the galaxies sufficient to resolve individual star-forming regions, and tracing the important heating and cooling channels of the ISM, across a wide range of local extragalactic ISM environments. This article summarizes the scientific strategy for KINGFISH, the properties of the galaxy sample, the observing strategy, and data processing and products. It also presents a com- bined Spitzer and Herschel image atlas for the KINGFISH galaxies, covering the wavelength range 3.6–500 μm. All imaging and spectroscopy data products will be released to the Herschel user-generated product archives.

INTRODUCTION origins of the spatially resolved radio-infrared correlation (Murphy et al. 2006a, 2006b, 2008); testing and calibration Observations of star formation and the interstellar medium of dust-corrected measurements of the star formation rate (ISM) in nearby galaxies form a vital bridge between in-depth (e.g., Calzetti et al. 2005, 2007, 2010; Pérez-González et al. studies of individual interstellar clouds and star-forming regions 2006; Kennicutt et al. 2009; Li et al. 2010), studies of the form in the Galaxy and the globally integrated measurements of dis- of the star formation rate (SFR) versus gas density law (e.g., tant galaxies.

Stanford11, E. Wright3 Accepted for Publication in the Astronomical Journal ABSTRACT The Wide-field Infrared Survey Explorer (WISE) mapped the entire sky at mid-infrared wavelengths 3.4 µm, 4.6 µm, 12 µm and 22 µm. The mission was primarily designed to extract point sources, leaving resolved and extended sources, for the most part, unexplored. Accordingly, we have begun a dedicated WISE Enhanced Resolution Galaxy Atlas (WERGA) project to fully characterize large, nearby galaxies and produce a legacy image atlas and source catalogue. Here we demonstrate the first results of the WERGA-project for a sample of 17 galaxies, chosen to be of large angular size, diverse morphology, and covering a range in color, stellar mass and star formation. It includes many well- studied galaxies, such as M 51, M 81, M 87, M 83, M 101, IC 342. Photometry and surface brightness decomposition is carried out after special super-resolution processing, achieving spatial resolutions similar to that of Spitzer -IRAC. The enhanced resolution method is summarized in the first paper of this two part series. In this second work, we present WISE, Spitzer and GALEX photometric and characterization measurements for the sample galaxies, combining the measurements to study the global properties.

In two cases, Hydra A and 3C 285, the Balmer and l4000-A˚ break indices constrain the spectral types and luminosity classes of the stars involved, revealing that the blue spectra are dominated by blue supergiant and/or giant stars. The ages derived for the last burst of star formation in Hydra A are between 7 and 40 Myr, and in 3C 285 about 10 Myr. The rest of the narrow-line radio galaxies (four) have a l4000-A˚ break and metallic indices consistent with those of elliptical galaxies. The only broad-line radio galaxy in our sample, 3C 382, has a strong featureless blue continuum and broad emission lines that dilute the underlying blue stellar spectra. We are able to detect the Ca II triplet in absorption in the seven objects, with good quality data for only four of them.

Here, we searched for substructure in the MBH –(central velocity dispersion, σ) diagram using our recently published, multi- component, galaxy decompositions; investigating divisions based on the presence of a depleted stellar core (major dry-merger), a disk (minor wet/dry-merger, gas accretion), or a bar (evolved unstable 5.75±0.34 disk). The S´ersic and core-S´ersic galaxies define two distinct relations: MBH ∝ σ and MBH ∝ 8.64±1.10 σ , with ∆rms|BH = 0.55 and 0.46 dex, respectively. We also report on the consistency with the slopes and bends in the galaxy luminosity (L)–σ relation due to S´ersic and core-S´ersic ETGs, and LTGs which all have S´ersic light-profiles.

A new generation of spectral synthesis models has been developed in the recent years, but there is no matching – in terms of quality and resolution – set of template galaxy spectra for testing and refining the new models. Aims. Our main goal is to find and calibrate new near-infrared spectral indices along the Hubble sequence of galaxies which will be used to obtain additional constraints to the population analysis based on medium resolution integrated spectra of galaxies. Methods. Spectra of previously studied and well understood galaxies with relatively simple stel- lar populations (e.g., ellipticals or bulge dominated galaxies) are needed to provide a baseline data set for spectral synthesis models.

ABSTRACT Different massive black hole mass - host galaxy scaling relations suggest that the growth of massive black holes is entangled with the evolution of their host galaxies. The number of measured black hole masses is still limited, and additional measurements are necessary to understand the underlying physics of this apparent co-evolution. We add six new black hole mass (MBH) measurements of nearby fast rotating early-type galaxies to the known black hole mass sample, namely NGC 584, NGC 2784, NGC 3640, NGC 4570, −1 NGC 4281 and NGC 7049.

After visual inspection of each match, we are left with 130 galaxies with reliable GALEX pipeline photometry in the far-UVand near-UV bands. This sample is divided into ellipticals (À5:5 T < À3:5) and lenticulars (À3:5 T < À1:5). After correction for Galactic extinction, the color-color diagrams FUV À NUV versus (B À V )Tc are plotted for the two subsamples.

  • Making a Sky Atlas
    Appendix A Making a Sky Atlas Although a number of very advanced sky atlases are now available in print, none is likely to be ideal for any given task. Published atlases will probably have too few or too many guide stars, too few or too many deep-sky objects plotted in them, wrong- size charts, etc. I found that with MegaStar I could design and make, specifically for my survey, a “just right” personalized atlas. My atlas consists of 108 charts, each about twenty square degrees in size, with guide stars down to magnitude 8.9. I used only the northernmost 78 charts, since I observed the sky only down to –35°. On the charts I plotted only the objects I wanted to observe. In addition I made enlargements of small, overcrowded areas (“quad charts”) as well as separate large-scale charts for the Virgo Galaxy Cluster, the latter with guide stars down to magnitude 11.4. I put the charts in plastic sheet protectors in a three-ring binder, taking them out and plac- ing them on my telescope mount’s clipboard as needed. To find an object I would use the 35 mm finder (except in the Virgo Cluster, where I used the 60 mm as the finder) to point the ensemble of telescopes at the indicated spot among the guide stars. If the object was not seen in the 35 mm, as it usually was not, I would then look in the larger telescopes. If the object was not immediately visible even in the primary telescope – a not uncommon occur- rence due to inexact initial pointing – I would then scan around for it.

BARTH Draft version 6 ABSTRACT Motivated by recent developments in our understanding of the formation and evolution of massive galaxies, we explore the detailed photometric structure of a representative sample of 94 bright, nearby elliptical galaxies, using high-quality optical images from the Carnegie-Irvine Galaxy Survey. The sample spans a range of environ- 10.2 12.0 ments and stellar masses, from M∗ = 10 to 10 M⊙. We exploit the unique capabilities of two-dimensional image decomposition to explore the possibility that local elliptical galaxies may contain photometrically distinct substructure that can shed light on their evolutionary history. Compared with the traditional one-dimensional ap- proach, these two-dimensional models are capable of consistently recovering the surface brightness distribution and the systematic radial variation of geometric informationat the same time. Contrary to conventionalperception, we find that the global light distribution of the majority (>75%) of elliptical galaxies is not well described by a single Sérsic function. Instead, we propose that local elliptical∼ galaxies generically contain three subcomponents: a compact (Re <1 kpc) inner component with luminosity fraction f 0.1 − 0.15; an intermediate-scale (Re 2.5 ≈ ≈ kpc) middle component∼ with f 0.2 − 0.25; and a dominant ( f =0.6), extended (Re 10 kpc) outer envelope.

We detect CO emission 8 in 12 of the galaxies at >4σ significance, with molecular gas masses in the range ∼0:01−6 × 10 M , as well as CO in absorption in the non-dominant group member galaxy NGC 5354. In total 21 of the 53 CLoGS dominant galaxies are detected in CO and we −1 confirm our previous findings that they have low star formation rates (0.01–1 M yr ) but short depletion times (<1 Gyr) implying rapid replenishment of their gas reservoirs.
