# Updated 34-Band Photometry for the SINGS/KINGFISH Samples of Nearby Galaxies

## TL;DR

This paper updates the broadband photometry database for 79 nearby galaxies from the KINGFISH and SINGS surveys, covering 34 spectral bands from ultraviolet to radio, providing a comprehensive multi-wavelength reference for low-redshift galaxy studies.

## Contribution

It provides an updated, recalibrated 34-band photometric dataset for the combined KINGFISH and SINGS galaxy samples, integrating data from multiple observatories.

## Key findings

- Submillimeter emission excess observed in low-metallicity galaxies
- Recalibration of previous infrared/submillimeter photometry
- Dataset serves as a key multi-wavelength reference for nearby galaxies

## Abstract

We present an update to the ultraviolet-to-radio database of global broadband photometry for the 79 nearby galaxies that comprise the union of the KINGFISH (Key Insights on Nearby Galaxies: A Far-Infrared Survey with Herschel) and SINGS (Spitzer Infrared Nearby Galaxies Survey) samples. The 34-band dataset presented here includes contributions from observational work carried out with a variety of facilities including GALEX, SDSS, PS, NOAO, 2MASS, WISE, Spitzer, Herschel, Planck, JCMT, and the VLA. Improvements of note include recalibrations of previously-published SINGS BVRcIc and KINGFISH far-infrared/submillimeter photometry. Similar to previous results in the literature, an excess of submillimeter emission above model predictions is seen primarily for low-metallicity dwarf/irregular galaxies. This 34-band photometric dataset for the combined KINGFISH$+$SINGS sample serves as an important multi-wavelength reference for the variety of galaxies observed at low redshift. A thorough analysis of the observed spectral energy distributions is carried out in a companion paper.
