Abstract:
Observations of evolution in the dust-to-metal ratio allow to
constrain the dominant dust processing mechanisms. In this work, we
present a study of the dust-to-metal and dust-to-gas ratios in a
subsample of ∼500 DustPedia galaxies. Using literature and MUSE
emission line fluxes, we derive gas-phase metallicities (oxygen
abundances) for over 10000 individual regions and determine
characteristic metallicities for each galaxy. We study how the
relative dust, gas and metal contents of galaxies evolve by using
metallicity and gas fraction as proxies for evolutionary state. The
global oxygen abundance and nitrogen-to-oxygen ratio are found to
increase monotonically as galaxies evolve. Additionally, unevolved
galaxies (gas fraction >60%, metallicity 12+log(O/H)<8.2) have
dust-to-metal ratios that are about a factor of 2.1 lower (factor of 6
lower for galaxies with gas fraction >80%) than the typical
dust-to-metal ratio (Md/MZ∼0.214) for more evolved sources.
However, for high gas fractions, the scatter is larger due to larger
observational uncertainties as well as a potential dependence of the
dust grain growth timescale and supernova dust yield on local
conditions and star formation histories. We find chemical evolution
models with a strong contribution from dust grain growth describe
these observations reasonably well. The dust-to-metal ratio is also
found to be lower for low stellar masses and high specific star
formation rates (with the exception of some sources undergoing a
starburst). Finally, the metallicity gradient correlates weakly with
the HI-to-stellar mass ratio, the effective radius and the
dust-to-stellar mass ratio, but not with stellar mass.
Description:
This work presents a large, homogeneous set of resolved metallicities
(10143 individual regions) and global metallicity and HI measurements
for the DustPedia sample (largest sample of nearby galaxies observed
with Herschel). The data in this work is available as six separate
tables. The first table compiles the HI fluxes, uncertainties and
masses. The references for the HI compilation are given in our second
table. The third table lists the references used in the compilation of
emission line fluxes. The next table gives the reddening-corrected
emission line fluxes for the compiled emission lines from the
literature, combined with the extracted MUSE spectrophotometry, for
all the regions that are classified as star-forming. The fifth table
lists the oxygen abundances and corresponding bootstrapped
uncertainties using multiple calibration methods for each of these
star-forming regions. The reddening coefficients are listed in both
the emission line and metallicity table for each individual region.
Our final table presents the available global metallicities for each
of the galaxies in our sample, together with their uncertainties. For
