cds-question@unistra.fractive-galactic-nucleigalaxy-classification-systemsThe mechanisms that bring galaxies to strongly reduce their star formation activity (star-formation quenching) remain poorly understood. To better study galaxy evolution, we propose a classification based on maps of ionised hydrogen distribution traced by the kiloparsec-resolved, equivalent width of H{alpha} maps, and the nuclear activity of the galaxies using information from the Baldwin-Philips-Terlevich diagnostic diagrams. Using these tools, we group a sample of 238 galaxies from the Calar Alto Legacy Integral Field spectroscopy Area survey in six quenching stages (QSs): (i) objects dominated by recent star formation; (ii) systems that present a quiescent-nuclear-ring structure in their centre; (iii) galaxies that are centrally quiescent; (iv) galaxies with no clear pattern in their ionisation gas distribution (mixed); (v) systems that posses only a few star-forming regions (nearly retired), or (vi) galaxies that are completely quiescent (fully retired). Regarding their nuclear activity, we further divide the galaxies into two groups: active systems that host a weak or strong active galactic nucleus (AGN) at their centre, and non-active objects. Galaxies grouped into quenching-stage classes occupy specific locations on the star-formation-rate versus stellar mass diagram. The 'blue cloud' is populated by the star-forming and the quiescent-nuclear-ring galaxies, the 'green valley' is populated by centrally quiescent and mixed systems, and the 'red sequence' by the nearly- and fully retired objects. Generally, galaxies that host a weak or strong AGN show properties comparable to those of their non-active counterparts at the same QSs, except for the AGN-hosting star-forming systems. The degree of star-formation quenching increases along the present emission-line pattern sequence from star-forming to fully retired. The proposed emission-line classes reinforce the 'inside-out' quenching scenario, which foresees that the suppression of star formation begins from the central regions of the galaxies.2021A&A...648A..64Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/648/A64CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/469/2539 : New classification of CALIFA galaxies (Kalinova+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/648/A64https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/648/A64http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/648/A64https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/648/A64https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/648/A64http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/648/A64GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/648/A64/tableb1 (Properties of the 238 (E1-Sdm) CALIFA galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/648/A64/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/648/A64/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/648/A64/tableb1?GETtext/xml+votable180.050000true118.846788126.74112190.0055555555555555566/545 552 554 620 738 909 948-949 975 2206 2228 2248 2251 2274 2276 2290 4053 4167 4178 4342 4445 4507 4511 4654 4801 4806 4813 4829 4840 4843 4950 4957 5028 5247 5298 5332 5505 5533 5593 5701 5889 6214 6216 6241 6261 6270 6342 6541 7214 7340 7560 7589 7824 7834 7844 8045 8341 8477 8498 8522 8562-8563 8656 8883 9124 9187 9216 9220 9381 9470-9471 9622 9628 9630 9695 9718 9798 9812 9875 9883 9885 9891 9946 9974 10111 10183 10220-10221 10380-10381 10398 10400 10515 10566 10583 10588 10595 10612 10627-10628 10674 10705 10739-10740 10773 10778 10987 11044 11070 11112 11164 11196 11290 11369 11372 11377 11383 11392 11396 11435 11525 11544 11832 11905 11944 12532 12709 13316 13380-13381 13426 13529 15002 16007 16696 16702 16788 17233-17234 17237 17350 17398 17486 17499 17578 17751 17758 17819 18008 18069 18071 18173 18241 18295 18302 18383 18775 18779 18800 18854 18931-18932 18935 18941 19073 19108 19227 19260 19387 19458 19508 19538 19618 19633 19642 19848 19939 19954 19981 19984 19996 20009 20020 20023 20031-20033 20193 20254 20279 20417 20429 22364 22652 22737 22741 23273 23337 26495 27133 27608 27719 28365 28430 28458 28513 28522 28617 28639 29973 31546 31628 31643 31688-31689 31737 32462 32471 32478 32482 32559 48880 49121 49130https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/648/A64?format=asciiOpticaldefaultJ/A+A/648/A64/tableb1Properties of the 238 (E1-Sdm) CALIFA galaxiesrecnoRecord number assigned by the VizieR team.
