Here, we look for additional trends at fixed {sigma}_e_ using 1339 galaxies (M_*_>~6x10^9^M_{sun}_) with different morphologies in the MaNGA (DR14) sample with integral-field spectroscopy data. We focus on the gradients ({gamma}_rms_={sigma}(R_e_/4)/{sigma}_e_) of the stellar root-mean-square velocity (V_rms_=sqrt(V^2^+{sigma}^2^)), which we show traces the total mass density gradient {gamma}_tot_ derived from dynamical models and, more weakly, the bulge fraction. We confirm that {gamma}_rms_ increases with {sigma}_e_, age, and metallicity. We additionally find that these correlations still exist at fixed {sigma}_e_, where galaxies with larger {gamma}_rms_ are found to be older and more metal-rich. It means that mass density gradients contain information of the stellar population which is not fully accounted for by {sigma}_e_. This result puts an extra constraint on our understanding of galaxy quenching. We compare our results with galaxies in the IllustrisTNG hydrodynamical simulations and find that, at fixed {sigma}_e_, similar trends exist with age, the bulge fraction, and the total mass density slope but, unlike observations, no correlation with metallicity can be detected in the simulations.2020MNRAS.495.4820Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/495/4820CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/154/86 : MaNGA catalog, DR15 (Wake+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/495/4820https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/495/4820http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/495/4820https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/495/4820https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/495/4820http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/495/4820GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/495/4820/tables1 (Related parameters of 1339 MaNGA galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/4820/tables1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/4820/tables1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/4820/tables1?GETtext/xml+votable180.050000true262.676395356.63938920.0055555555555555565/1279 1383 1390 1400 1419 1439 1450 1456 1553 1599 1640-1641 1644-1646 1662 1728 2316 2367 2379 2401 2457 2528 2545 2594 2668 2672 2737-2738 2758 2845 2849 4774 7510 6/4661 4663 4704-4706 4712 4794-4795 4798 4817 4819 4825-4827 4846-4847 4857 4861 4918-4919 4925 4960 4962 4968 5338 5349-5351 5356 5358-5360 5362-5363 5369 5371-5372 5374-5375 5463 5469-5471 5492-5494 5523 5528 5531 5551 5553 5555-5556 5558-5559 5564-5565 5567 5574-5576 5578-5579 5581-5584 5592 5594 5604-5606 5611-5612 5615 5670 5680 5690 5716 5727 5738 5743 5750-5752 5754-5755 5781 5783 5789 5797-5799 5806 5808 5810 5819 5828 5831 5833-5834 5836 5838 5841 5844-5846 5857 5859 5862 5865 5867-5868 5870 5888-5890 5904 5917-5920 5922-5923 5926 5928-5929 5954-5956 5958 6161 6209 6217 6223 6226 6244 6247 6270-6271 6359 6367 6385 6389-6391 6393 6395 6440 6442 6520-6521 6523 6528 6537-6540 6542-6543 6547 6552-6553 6555-6556 6559 6570-6571 6573-6574 6602-6603 6606 6608 6612 6622 6624-6625 6628 6630-6631 6637-6641 6643-6644 6653-6655 6741-6743 6916-6917 6928-6929 6932 6976 6992 7169 7172-7173 7175 7184 7186 7215 7225-7226 7230-7231 7235-7237 7301 7308 7311 7313-7315 7317-7318 7320 7323-7324 7330-7331 7337-7339 7360-7361 7363-7364 7366-7370 7680-7681 8701-8702 8888 8890-8891 9031 9045-9046 9110-9111 9116-9117 9119 9154-9155 9162 9215 9242 9335 9341 9386 9459 9462-9463 9465 9467 9472 9474 9480 9506 9509-9513 9520 9601 9609 9612 9632-9634 9638 9640-9642 9644 9646-9647 9728 9777 9780 9784-9785 9787-9788 9790 9807-9808 9811 9813-9815 9817-9818 9820-9822 9840-9841 9844 9883 9887 9893 9898-9899 9901-9902 9905-9906 9909 9911-9912 9914 9930 9933 9942-9943 9946 9953 9956 9958 9961-9964 9985-9988 9990 9992-9993 10017 10019 10022 10025 10027 10093 10095-10096 10098-10099 10104-10106 10120 10179 10192 10194 10200 10213 10215 10221 10226 10256-10257 10269-10271 10292-10293 10295 10312 10336 10380 10382 10400 10484 10487 10493 10551 10580 10583 10593-10595 10600 10602-10603 10633 10635-10638 10649 10652 10654 10656-10658 10663 10676 10692 10695 10699-10702 10707 10710 10712-10713 10716 10725 10736 10855 10857 10863 10866-10867 10869-10873 10911 10927 10929-10930 10932-10934 10937 10939-10941 10956-10957 10959-10960 10962 10976-10978 11019 11023 11036-11037 11040-11042 11044-11045 11047 11053 11058 11264-11265 11268-11269 11301 11303 11310-11311 11322-11323 11326 11347-11350 11355-11358 11377 11384 11393 11405-11410 11412 11414 11416 11428 11528 11587-11588 11593-11595 12380-12381 12383 12387 12389-12391 12397-12399 12552 12554 17746-17747 17750 17753 17756 17758 18769 18771-18772 18777 18779-18780 18782 19086 19109 19120-19122 19382 19387 19389-19390 19432 23057 23059-23060 23101-23103 23144 23146 23182-23183 23185-23187 23189-23190 23192 23194-23195 23197-23198 23201 23203-23206 23212 23216 23218 23232-23233 28127 28148 28271 28280 28282-28283 28340-28341 28356 28358 28369-28370 28385 28627 28629-28630 28633 28636 30035 30065 32499 32501-32503 32508-32509 32672 32680https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/495/4820?format=asciiUVOpticaldefaultJ/MNRAS/495/4820/tables1Related parameters of 1339 MaNGA galaxiesSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
