cds-question@unistra.frgalaxiesultraviolet-photometryvisible-astronomyinfrared-astronomyThe study of scaling relations of disc galaxies and their evolution across cosmic time requires accurate estimates of galaxy stellar masses Mstar over broad redshift ranges. While photometric Mstar estimates (Mphot) based on spectral energy distribution (SED) modelling methods are employed routinely at high-z, it is unclear to what extent these are compatible with dynamical Mstar estimates (Mdyn), available for nearby galaxies. Here we compare newly determined, SED-model based Mphot with previously obtained Mdyn inferred via rotation curve decomposition techniques in a sample of ~100 nearby galaxies from the SPARC database. We find that the two mass estimates show a systematic agreement at the 12% (0.05dex) level and a ~55% (0.22dex) scatter across almost 5dex in Mstar. Our Mphot estimates correspond to mass-to-light ratios in the 3.6um band that increase gradually with 3.6um luminosity, as a consequence of the earlier (later) assembly history of high-mass (low-mass) disc galaxies. The choice of using either Mdyn or Mphot has only a marginal impact on the slope and zero-point of the Tully-Fisher and Fall relations: the observed orthogonal scatter in both relations is virtually the same for the two methods, and indistinguishable from that derived using a constant mass-to-light ratio in the 3.6um band. Mstar estimates based on the assumption that discs are marginally stable lead to the largest scatter in the scaling relations.2025A&A...695L..23Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/695/L23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/152/157 : Mass models for 175 disk galaxies with SPARC (Lelli+, 2016)J/A+A/612/L6 : j-M law from dwarf to massive spirals (Posti+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/695/L23https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/695/L23http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/695/L23https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/695/L23https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/695/L23http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/695/L23GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/695/L23/tablec1 (Photometry catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/695/L23/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/695/L23/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/695/L23/tablec1?GETtext/xml+votable180.050000true147.594868931.48827690.0055555555555555566/816 955 975 1007 1114 1561 2071 2169 2351 2383 2409 2866 3511 3519 4511 4534 5067 5124 5168 5174 5230 5329 5463 5469 5500 5503-5504 5581 5584 5587 5589 5591 5594 5596 5599 5623 5625 5628-5629 5631 5636 5669 5710 5751 5827 5956 5967 5975 5982 6604 6623 7132 7241 7303 7523 7602 7624 7743 7799 7878 7882 7946 7957 9463 9855 10282 10286 10475 10511 10637 10662 10689 10809 10817 10841 10847 10881 10908 10910 10924-10925 10927 10930 10935 10941 10955 10970 10976 10979 10990-10991 11000 11006 11019 11030 11092 11127 11375 11389 11448 11566 11639 11696 12570 13489 13522 13668 15551 15592 16016 16083 16441 16519 16595 16701 17165 17753 18315 18378 19570 19697 19843 20020 20353 20438 24952 26106 27030 27468 28077 28087 28149 28230 28463 28496 28535 28631 28637-28638 32231 33435 33589 33986 35514 35536 35746 36974 38846 40531 439728.157980699529898e-21 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/695/L23?format=asciiUVOpticalInfrareddefaultJ/A+A/695/L23/tablec1Photometry catalogueGalaxyGalaxy namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
