“…Although the bandpass does not match WISE perfectly, as above this provides a large sample to benchmark against. Dale et al (2017) conducted careful, by-hand aperture definition and removal of foreground stars to derived integrated photometry for the KINGFISH galaxies (see also Cluver et al 2017). Clark et al (2018) adopt a more automated approach, similar to what we do here.…”

We present an atlas of ultraviolet and infrared images of ∼ 15, 750 local (d 50 Mpc) galaxies, as observed by NASA's WISE and GALEX missions. These maps have matched resolution (FWHM 7.5 and 15 ), matched astrometry, and a common procedure for background removal. We demonstrate that they agree well with resolved intensity measurements and integrated photometry from previous surveys. This atlas represents the first part of a program (the z = 0 Multi-wavelength Galaxy Synthesis) to create a large, uniform database of resolved measurements of gas and dust in nearby galaxies. The images and associated catalogs will be publicly available at the NASA/IPAC Infrared Science Archive. This atlas allows us estimate local and integrated star formation rates (SFRs) and stellar masses (M ) across the local galaxy population in a uniform way. In the appendix, we use the population synthesis fits of Salim et al. (2016Salim et al. ( , 2018 to calibrate integrated M and SFR estimators based on GALEX and WISE. Because they leverage an SDSS-base training set of > 100, 000 galaxies, these calibrations have high precision and allow us to rigorously compare local galaxies to Sloan Digital Sky Survey results. We provide these SFR and M estimates for all galaxies in our sample and show that our results yield a "main sequence" of star forming galaxies comparable to previous work. We also show the distribution of intensities from resolved galaxies in NUV-to-WISE1 vs. WISE1-to-WISE3 space, which captures much of the key physics accessed by these bands.

“…Previous works have suggested that some of this scatter may be due to the time-dependent nature of N/O production (i.e., a N/O "clock" ;Garnett 1990;Pilyugin 1999;Henry et al 2006). A directly observable effect of an aging ionizing stellar population is an increasing fraction of low-to high-ionization gas in the H II region (see, for example, how the shape of the ionizing continuum changes with age in Chisholm et al 2019).…”

The chemical abundances of spiral galaxies, as probed by H II regions across their disks, are key to understanding the evolution of galaxies over a wide range of environments. We present LBT/MODS spectra of 52 H II regions in NGC3184 as part of the CHemical Abundances Of Spirals (CHAOS) project. We explore the direct-method gas-phase abundance trends for the first four CHAOS galaxies, using temperature measurements from one or more auroral line detections in 190 individual H II regions. We find the dispersion in T e − T e relationships is dependent on ionization, as characterized by F λ5007 /F λ3727 , and so recommend ionization-based temperature priorities for abundance calculations. We confirm our previous results that [N II] and [S III] provide the most robust measures of electron temperature in low-ionization zones, while [O III] provides reliable electron temperatures in highionization nebula. We measure relative and absolute abundances for O, N, S, Ar, and Ne. The four CHAOS galaxies marginally conform with a universal O/H gradient, as found by empirical IFU studies when plotted relative to effective radius. However, after adjusting for vertical offsets, we find a tight universal N/O gradient of α N/O = −0.33 dex/R e with σ tot. = 0.08 for R g /R e < 2.0, where N is dominated by secondary production. Despite this tight universal N/O gradient, the scatter in the N/O-O/H relationship is significant. Interestingly, the scatter is similar when N/O is plotted relative to O/H or S/H. The observable ionic states of S probe lower ionization and excitation energies than O, which might be more appropriate for characterizing abundances in metal-rich H II regions. Spectral ReductionsFor a detailed description of the data reduction procedures we refer the reader to (B15). Here, we only note the primary points of our data processing. Spectra were reduced and analyzed using the beta-version of the MODS reduction pipeline 1 which runs within the XIDL 2 reduction package. Given that the bright disks of CHAOS galaxies can complicate local sky subtraction, 1

“…There are many other parameters that are measured and cataloged (e.g., nuclear concentration), but are otherwise not discussed here, details will be given in Paper II. The basic source characterization pipeline has a heritage that extends from the 2MASS Extended Source Catalogue (Jarrett et al 2000), also used in the WISE processing pipeline, and various aspects have been discussed in previous WISE work (Jarrett et al 2011(Jarrett et al , 2013Cluver et al 2014;Jarrett et al 2017;Cluver et al 2017). Below we add some additional detail relevant to large galaxies.…”

We present mid-infrared photometry and measured global properties of the 100 largest galaxies in the sky, including the well-studied Magellanic Clouds, Local Group galaxies M 31 and M 33, the Fornax and Virgo Galaxy Cluster giants, and many of the most spectacular Messier objects (e.g., M 51 and M 83). This is the first release of a larger catalog of extended sources as imaged in the mid-infrared, called the WISE Extended Source Catalogue (WXSC). In this study we measure their global attributes, including integrated flux, surface brightness and radial distribution. The largest of the large are the LMC, SMC and the Andromeda Galaxy, which are also the brightest mid-infrared galaxies in the sky. We interrogate the large galaxies using WISE colors, which serve as proxies for four general types of galaxies: bulge-dominated spheroidals, intermediate semi-quiescent disks, star-forming spirals, and AGN-dominated. The colors reveal a tight "sequence" that spans 5 magnitudes in W2−W3 color, ranging from early to late-types, and low to high star-forming activity; we fit the functional form given by: (W1 − W2) = [0.015 × e (W2−W3) 1.38 ] − 0.08. Departures from this sequence may reveal nuclear, starburst, and merging events. Physical properties and luminosity attributes are computed, notably the diameter, aggregate stellar mass and the dust-obscured star formation activity. To effectively study and compare these galaxy characteristics, we introduce the 'pinwheel' diagram which depicts physical properties with respect to the median value observed for WISE galaxies in the local universe. Utilized with the WXSC, this diagram will delineate between different kinds of galaxies, identifying those with similar star formation and structural properties. Finally, we present the mid-infrared photometry of the 25 brightest globular clusters in the sky, for which many are also the largest and brightest objects orbiting the Milky Way, including Omega Centauri, 47 Tucanae and a number of famed night-sky targets (e.g., M 13).
