cds-question@unistra.frgalaxiesspectroscopyactive-galactic-nucleichemical-abundancesline-intensitiesWe discuss the nature and origin of the nuclear activity observed in a sample of 292 SDSS narrow-emission-line galaxies, considered to have formed and evolved in isolation. All these galaxies are spiral like and show some kind of nuclear activity. The fraction of Narrow Line AGNs (NLAGNs) and Transition type Objects (TOs; a NLAGN with circumnuclear star formation) is relatively high, amounting to 64% of the galaxies. There is a definite trend for the NLAGNs to appear in early-type spirals, while the star forming galaxies and TOs are found in later-type spirals. We verify that the probability for a galaxy to show an AGN characteristic increases with the bulge mass of the galaxy (Torres-Papaqui et al. 2011), and find evidence that this trend is really a by-product of the morphology, suggesting that the AGN phenomenon is intimately connected with the formation process of the galaxies. Consistent with this interpretation, we establish a strong connection between the astration rate -- the efficiency with which the gas is transformed into stars - the AGN phenomenon, and the gravitational binding energy of the galaxies: the higher the binding energy, the higher the astration rate and the higher the probability to find an AGN. The NLAGNs in our sample are consistent with scaled-down or powered-down versions of quasars and Broad Line AGNs.2011RMxAA..47..361Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RMxAA/47.361CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RMxAA/47.361https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RMxAA/47.361http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RMxAA/47.361https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RMxAA/47.361https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RMxAA/47.361http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RMxAA/47.361GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RMxAA/47.361/nelg (Properties and results of isolated Narrow-emission line galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RMxAA/47.361/nelg?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RMxAA/47.361/nelg?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RMxAA/47.361/nelg?GETtext/xml+votable180.050000true164.54102-0.774680.0055555555555555566/550 4147 4222 4231 4269 4279 4289 4366 4403 4405 4429 4487 4537 4551 4570 4572 4583 4666 4698 4789 4820 4852 4885 4910 4934 4955 4969 5046 5047 5096 5117 5151 5215 5233 5239 5255 5266 5272 5309 5320 5326 5335 5376 5520 5534 5545 5666 5677 5678 5683 5684 5736 5751 5762 5818 5822 5849 5859 5862 5884 5922 5947 5978 6049 6068 6120 6161 6366 6438 6460 6465 6482 6496 6509 6518 6579 6637 7170 7183 7185 7234 7268 7282 7310 7382 7393 7424 7440 7443 7452 7470 7498 7501 7518 7521 7582 8263 8279 8287 8291 8319 8327 8391 8433 8482 8508 8580 8591 8605 8683 8720 8752 8759 8840 8841 8848 8875 8888 8895 8900 9002 9088 9129 9228 9382 9388 9618 9637 9914 9940 9961 9993 10104 10226 10242 10269 10286 10328 10349 10364 10367 10373 10384 10385 10420 10444 10460 10497 10507 10546 10553 10563 10575 10577 10588 10598 10678 10701 10756 10761 10780 10784 10802 10929 10973 11004 11042 11074 11080 11093 11107 11120 11158 11162 11178 11218 11305 11342 11502 11596 11844 12400 12555 12560 12568 17253 17329 17751 17770 17811 18383 18518 18544 18781 18854 19051 19749 19751 19990 22366 22385 22388 23050 23052 23181 23213 25595 25930 25960 26008 26103 26163 26241 26291 26329 26331 26375 26381 26392 26529 26538 26621 26953 26970 26975 27032 27064 27262 27303 27304 27327 27335 27349 27369 27373 27384 27391 27428 27442 27468 27477 27508 27593 27633 27702 27710 27802 27840 27871 27879 27981 28017 28019 28054 28056 28074 28087 28178 28207 28279 28302 28379 28395 28437 28439 28473 28538 28544 28563 28572 28585 28650 29973 30038 30043 31401 31628 31643 31664 31670 31697 31723 31731 32438 36733 36765 36805 45050 45052 49098https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RMxAA/47.361?format=asciiOpticaldefaultJ/other/RMxAA/47.361/nelgProperties and results of isolated Narrow-emission line galaxiesrecnoRecord number assigned by the VizieR team.
