cds-question@unistra.frgalaxiesspectral-energy-distributionWe derived the dust properties for 753 local galaxies and examine how these relate to some of their physical properties. We present the derived dust emission properties, including model spectral energy distribution (SEDs), star formation rates (SFRs) and stellar masses, as well as their relations. We modelled the global dust-SEDs for 753 galaxies, treated statistically as an ensemble within a hierarchical Bayesian dust-SED modelling approach, so as to derive their infrared (IR) emission properties. To create the observed dust-SEDs, we used a multi-wavelength set of observations, ranging from near-IR to far-IR-to-submillimeter wavelengths. The model-derived properties are the dust masses (Mdust), the average interstellar radiation field intensities (Uav), the mass fraction of very small dust grains ("QPAH" fraction), as well as their standard deviations. In addition, we used mid-IR observations to derive SFR and stellar masses, quantities independent of the dust-SED modelling. We derive distribution functions of the properties for the galaxy ensemble and as a function of galaxy type. The mean value of Mdust for the early-type galaxies (ETGs) is lower than that for the late-type and irregular galaxies (LTGs and Irs, respectively), despite ETGs and LTGs having stellar masses spanning across the whole range observed. The U_av_ and "QPAH" fraction show no difference among different galaxy types. When fixing Uav to the Galactic value, the derived "QPAH" fraction varies across the Galactic value (0.071). The specific SFR increases with galaxy type, while this is not the case for the dust-specific SFR (SFR/M_dust_), showing an almost constant star formation efficiency per galaxy type. The galaxy sample is characterised by a tight relationship between the dust mass and the stellar mass for the LTGs and Irs, while ETGs scatter around this relation and tend towards smaller dust masses. While the relation indicates that Mdust may fundamentally be linked to M*, metallicity and U_av_ are the second parameter driving the scatter, which we investigate in a forthcoming work. We used the extended Kennicutt-Schmidt (KS) law to estimate the gas mass and the gas-to-dust mass ratio (GDR). The gas mass derived from the extended KS law is on average ~20% higher than that derived from the KS law, and a large standard deviation indicates the importance of the average star formation present to regulate star formation and gas supply. The average GDR for the LTGs and Irs is 370, and including the ETGs gives an average of 550.2019A&A...631A..38Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/631/A38CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/631/A38https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/631/A38http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/631/A38https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/631/A38https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/631/A38http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/631/A38GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/631/A38/tablea1 (Galaxy and derived physical properties from the model and the calibrations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/631/A38/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/631/A38/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/631/A38/tablea1?GETtext/xml+votable180.050000true213.2913-65.3390.0055555555555555565/6928 6930 6932 6941 6965 6984-6985 7008 6/697 764 909 971 1261 2320 2409 2777 3042 3278 3289 3389 3506 4439 4447 4469 4807 4829 4869 4989 5021 5075 5124-5125 5181-5183 5190 5196 5198 5200 5241 5244 5247 5283 5332 5342 5429 5440 5469 5492 5617 5629 5715 5751 5762 5773 5966 5975-5978 5981-5982 5999 6001 6011-6012 6037 6042 6046-6047 6087 6090 6093 6097 6099 6103-6104 6162 7132 7214 7241 7355 7374 7385 7393 7424 7442 7445 7536 7602 7604 7606-7607 7624 7631 7649 7653 7655 7659 7662 7743 7799 7898 7941 8001 8085 8106 8196 8320 8330 8359 9894 10151 10183 10280 10286 10298 10364 10380 10385 10402 10425 10429 10437 10448 10454 10456 10468 10474-10475 10544 10551 10592 10637 10662 10672 10684 10739 10755 10767 10769 10841 10847 10856 10888 10900-10901 10911 10924-10925 10927 10930 10941 10954 10977 10979 10990 11006 11010 11074 11180 11246 11253 11263 11306 11375 11392 11434-11435 11453 11457 11492 11933 11961 12018 12031 13522 15056 15204 15592 16197-16198 16441 16452 16464 16467 16479 16489 16500 16531 16544 16643 16645 16655 17076 17340-17341 17472 17594 17606 17612 17688 17691 17693 17754 18002 18004 18011 18013 18041 18158 18212 18398 18709 18755 18760 18793 18800 18802 18809 19491 20014 20023 20875 21450 21845 22803 23178 24957 25083 25575 25595 25599 25656 25748 25788 25790 25907 25918 25933 25935 25945-25947 25958 25960 25971-25972 25980 25997 26001 26055 26065 26068 26072 26088 26090-26091 26119 26128 26139 26157 26161 26166 26174-26175 26210 26214 26222-26223 26247 26260 26264-26265 26267 26271 26282 26285 26287 26290 26294 26301-26303 26307-26309 26311 26313-26314 26316-26318 26320 26323 26329-26331 26336 26338 26340 26343-26344 26346-26347 26349 26351 26361-26363 26365 26377 26388 26432 26472 26528 26537 26542 26858 27030 27079 27130 27186 27351 27514 27555 27580 27603 27606 27653 27668-27669 27671 27677 27716 27718-27719 27724-27725 27727 27734-27736 27738-27740 27742-27743 27749-27750 27757-27758 27761 27763 27770-27774 27811 27814 27823 27830 27841 27853 27855 27857-27859 27871 27907-27909 27913-27918 27922 27926 27931 27934 27944-27945 27947-27948 27955 28015 28023 28037-28040 28054 28056 28091 28123 28126 28141-28142 28149 28162 28167 28184 28191 28201 28208 28213 28220-28221 28234 28258 28264 28294 28299 28304 28348 28404 28416 28491 28496 28508 28529 28538 28631 28651 28653 29718 29795 33935 33945-33946 33950 33958 33986 34273 34401 34495 34509-34511 34520 34531 34533-34535 34537-34542 34544 34546 34552 34641 35243 35330 35536 35581 35691 35720 35746 35993 36107 36194-36195 36241 36286 36586 36621 36756 36785 36831 36974 37128 38125 38139 38347 38360 38390 38639 38653 38822 39201 39806 39836 39925 40124 40221 40373 40410 41122 41586 42016 42027 43233 43262 43420 43626 43845 43881 44660 45914 46150 46170 46175 46197 46399 46429 46568 46571 46573 46615 46887 46987 47047 47120https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/631/A38?format=asciidefaultJ/A+A/631/A38/tablea1Galaxy and derived physical properties from the model and the calibrationsNameName (name)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
