cds-question@unistra.frgalaxiesphotometryseyfert-galaxiesinfrared-photometryinfrared-sourcesWe present the colour and flux variability analysis at 3.4{mu}m (W1 band) and 4.6{mu}m (W2 band) of 492 narrow-line Seyfert 1 (NLSy1) galaxies using archival data from the Wide-field Infrared Survey Explorer (WISE). In the WISE colour-colour, (W1-W2) versus (W2-W3) diagram, ~58 per cent of the NLSy1 galaxies of our sample lie in the region occupied by the blazar category of active galactic nuclei (AGNs). The mean W1-W2 colour of candidate variable NLSy1 galaxies is 0.99+/-0.18mag. The average amplitude of variability is 0.11+/-0.07mag in long term (multiyear) with no difference in variability between W1 and W2 bands. The W1-W2 colour of NLSy1 galaxies is anticorrelated with the relative strength of [OIII] to H{beta}, strongly correlated with continuum luminosity, black hole mass, and Eddington ratio. The long-term amplitude of variability shows weak anticorrelation with the FeII strength, continuum luminosity and Eddington ratio. A positive correlation between colour as well as the amplitude of variability with the radio power at 1.4GHz was found for the radio-detected NLSy1 galaxies. This suggests non-thermal synchrotron contribution to the mid-infrared colour and flux variability in radio-detected NLSy1 galaxies.2019MNRAS.483.2362Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/483/2362CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)J/ApJ/792/30 : NEOWISE magnitudes for near-Earth objects (Mainzer+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/483/2362https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/483/2362http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/483/2362https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/483/2362https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/483/2362http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/483/2362GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/483/2362/table1 (Variability information)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/483/2362/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/483/2362/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/483/2362/table1?GETtext/xml+votable180.050000true182.438432.28360.0055555555555555566/27 554 4105 4122 4179 4191 4215 4326 4336 4352 4369 4412 4493 4549 4565-4566 4570 4572 4653 4706 4709 4888 4943 4959 4995 5022 5031-5032 5092-5093 5111 5118 5153 5170 5180 5328 5337 5345 5352 5375 5427 5434 5446 5494 5505-5506 5523 5529 5534 5568 5577 5654 5748 5800 5816 5824 5840 5860 5862 5870 5879 5919 5921 5930 5947 5961-5962 6006 6018 6028 6030 6070 6080 6097 6106 6114 6125 6128 6260 6264 6469 6484 6494 6517-6518 6582 6585 6613 6739 6741 7174-7175 7198 7211 7219 7226 7245 7249 7259 7267 7285 7289 7298 7325 7337 7339 7357 7383 7415 7458 7461 7492-7493 7587 8199 8208 8234-8235 8271 8287 8328 8363 8369 8377 8392 8396 8408 8410 8422 8428 8446 8456 8522 8590 8610 8614 8618 8635 8644 8686 8695 8704-8705 8724 8727 8751 8755 8772 8778 8787 8804 8812 8830 8835 8858 8866 8877 8885 8898 8915 8918 8921 8935 8939 8945 8947 8952 8967 8973 8976 8989 9004 9019 9024 9029 9037 9043 9048 9050 9057 9060 9069 9084-9086 9091-9092 9095 9110 9127 9146 9159 9165 9171 9174 9181 9184 9188-9189 9196 9199 9208 9213 9264 9266 9272 9323 9401 9404 9415 9418 9427 9462 9469 9509 9515 9612 9729 9768 9770 9773 9784 9827 9837 9844 9883 9893 9915 9923 9927 9931 9935 9939 9948 9950 9959 9975 9987 10018 10020 10075 10085 10114 10145 10148 10182 10190 10214 10217 10269 10285 10313 10332 10361 10388-10389 10406 10409 10421 10424 10433 10442-10443 10447 10449 10460 10466-10467 10481 10510-10513 10527 10551 10568 10572 10574 10597 10614 10619 10686 10689 10698 10701 10712 10719 10739 10766 10788 10824 10869 10893 10930 11017 11030 11075 11085 11126 11184 11204 11239-11240 11250 11269-11270 11276 11281 11286 11292 11300 11319 11321 11353 11355 11371 11374 11383 11387 11391 11413 11419 11459 11464 11520 11530 11572 11587-11588 11593 11783 11806 11814 11832 11854 11875 11878 11909 11937 11944 12405 13334 17213 17507 17513 17574 17689 17692 17724 17766 17830 17840 18021 18098 18216 18341 18367 18409 18495 18616 18838 19037 19092 19109 19323 19685 19691 20343 20423 22389 23064 23076 23189 23191 23209 23211 23217 25846 25926 25948 25968 25972 25992 26022 26032 26038-26039 26056 26058 26070 26188 26199 26209 26239 26260 26295 26356 26369 26417 26433 26441 26462 26469-26471 26475 26525 26553 26557 26565 26568 26580 26965 26981 27001 27026 27038 27048 27053 27095 27098 27101 27118 27223 27243 27316 27320 27341 27349 27464 27482-27483 27538 27621 27650 27677 27765 27815 27849 27852 27863 27865 27902 27928 27950 27992 27997 28005 28031 28061 28091 28190 28225 28232 28234 28278 28340 28351 28423 28484 28486 28527 28604 28627 28629 28663 28668 30039 31323 31404 31411 31626 31634 31648 31665 31713 36731 36733 36759 36816 49017https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/483/2362?format=asciiInfrareddefaultJ/MNRAS/483/2362/table1Variability informationSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
