cds-question@unistra.frgalaxiesgalaxy-rotationIn a {Lambda} cold dark matter ({Lambda}CDM) cosmology, the baryonic Tully-Fisher relation (BTFR) is expected to show significant intrinsic scatter resulting from the mass-concentration relation of dark matter halos and the baryonic-to-halo mass ratio. We study the BTFR using a sample of 118 disk galaxies (spirals and irregulars) with data of the highest quality: extended HI rotation curves (tracing the outer velocity) and Spitzer photometry at 3.6{mu}m (tracing the stellar mass). Assuming that the stellar mass-to-light ratio ({Upsilon}_*_) is nearly constant at 3.6{mu}m, we find that the scatter, slope, and normalization of the BTFR systematically vary with the adopted {Upsilon}_*_. The observed scatter is minimized for {Upsilon}_*_>~0.5M_{Sun}_/L_{Sun}_, corresponding to nearly maximal disks in high-surface-brightness galaxies and BTFR slopes close to ~4. For any reasonable value of {Upsilon}_*_, the intrinsic scatter is ~0.1dex, below general {Lambda}CDM expectations. The residuals show no correlations with galaxy structural parameters (radius or surface brightness), contrary to the predictions from some semi-analytic models of galaxy formation. These are fundamental issues for {Lambda}CDM cosmology.2016ApJ...816L..14Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/816/L14CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/827/L19 : Central surface densities in SPARC disk galaxies (Lelli+, 2016)J/AJ/152/157 : Mass models for 175 disk galaxies with SPARC (Lelli+, 2016)J/AJ/147/134 : Tully-Fisher relation for S^4^G galaxies (Zaritsky+, 2014)J/A+A/566/A71 : HI study of 18 nearby dwarf galaxies (Lelli+, 2014)J/ApJ/765/94 : Calibration of the mid-IR Tully-Fisher relation (Sorce+, 2013)J/ApJ/669/821 : CO Tully-Fisher relation for host galaxies of QSOs (Ho+, 2007)J/AJ/134/945 : Tully-Fisher relation for SDSS galaxies (Pizagno+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/816/L14https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/816/L14http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/816/L14https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/816/L14https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/816/L14http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/816/L14GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/816/L14/figure2 (*Data behind Figure 2)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/816/L14/figure2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/816/L14/figure2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/816/L14/figure2?GETtext/xml+votable180.050000true119.254281114.39657110.0055555555555555566/975 1007 1114 1561 2351 2383 2409 2866 3511 3519 4511 4650 5067 5168 5174 5463 5469 5500 5503 5504 5581 5584 5587 5589 5591 5594 5596 5599 5623 5625 5628 5629 5631 5751 5827 5956 5967 5975 5982 6623 7132 7241 7303 7602 7624 7743 7882 7957 8557 9463 9855 10282 10286 10475 10511 10637 10662 10817 10841 10847 10908 10925 10927 10930 10941 10976 10979 10990 10991 11000 11019 11030 11127 11375 11448 11566 11639 13330 13489 13522 13668 15592 15594 16083 16519 16595 16701 17165 17753 18315 19570 19697 20020 20438 24952 26106 27030 28087 28107 28149 28230 28261 28346 28463 28535 28638 32231 33435 33589 35514 35536 35746 36974 38846 40531https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/816/L14?format=asciiOpticaldefaultJ/ApJ/816/L14/figure2*Data behind Figure 2SimbadNameSimbad column added by the CDSmeta.idcharNEDnameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
