cds-question@unistra.frgalaxiesspectroscopyvisible-astronomyredshiftedsurveysWe compare the radial profiles of the specific star formation rate (sSFR) in a sample of 169 star-forming galaxies in close pairs with those of mass-matched control galaxies in the SDSS-IV MaNGA survey. We find that the sSFR is centrally enhanced (within one effective radius) in interacting galaxies by ~0.3dex and that there is a weak sSFR suppression in the outskirts of the galaxies of ~0.1dex. We stack the difference profiles for galaxies in five stellar-mass bins in the range log(M/M_{sun}_)=9.0-11.5 and find that the sSFR enhancement has no dependence on the stellar mass. The same result is obtained when comparison galaxies are matched to each paired galaxy in both stellar mass and redshift. In addition, we find that the sSFR enhancement is elevated in pairs with nearly equal masses and closer projected separations, in agreement with previous work based on single-fiber spectroscopy. We also find that the sSFR offsets in the outskirts of the paired galaxies are dependent on whether the galaxy is the more-massive or less-massive companion in the pair. The more-massive companion experiences zero to a positive sSFR enhancement, while the less-massive companion experiences sSFR suppression in their outskirts. Our results illustrate the complex tidal effects on star formation in closely paired galaxies.2021ApJ...909..120Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/909/120CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020)J/ApJS/196/11 : Bulge+disk decompositions of SDSS galaxies (Simard+, 2011)J/MNRAS/466/2570 : Low ionization em.-line regions galaxies (Belfiore+, 2017)J/AJ/154/86 : MaNGA catalog, DR15 (Wake+, 2017)J/ApJ/901/159 : MaNGA AGNs from WISE, Swift, NVSS & FIRST (Comerford+, 2020)J/MNRAS/492/3073 : CALIFA galaxies hosting an AGN (Lacerda+, 2020)J/MNRAS/507/300 : Massive Compact Galaxies in MaNGA (Schnorr-Mueller+, 2021)J/other/RAA/21.306 : Supernova host galaxies in SDSS-IV MaNGA (Zhang+, 2021)J/A+A/659/A131 : Ionized Gas Kinematics in MaNGA AGN (Deconto-Machado+, 2022)http://www.nsatlas.org/ : NASA-Sloan Atlas home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/909/120https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/909/120http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/909/120https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/909/120https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/909/120http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/909/120GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/909/120/table1 (*Close galaxy pairs and multiples in MaNGA integral field units (IFUs))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/909/120/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/909/120/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/909/120/table1?GETtext/xml+votable180.050000true229.525575842.74585380.0055555555555555566/523 544 4131 4319 4341 4383 4426 4451 4666 4704-4705 4713 4734 4754-4755 4758 4784 4786 4795 4807 4813 4818 4822-4824 4841-4842 4844 4848 4908 4922-4923 4999 5001 5008 5016 5025 5119 5294-5295 5327 5349 5362 5370 5372 5532-5534 5547 5553 5560 5564 5590 5594 5603 5606 5608 5617 5629 5650 5665 5690 5748 5755 5799 5816 5824-5825 5831 5890 5907 5957 5959-5961 5965-5966 5969 5978-5979 5988 6220 6223 6225-6226 6228 6233 6238-6239 6241 6244-6245 6258 6270-6271 6340 6397-6399 6436 6445 6448 6450 6456 6461-6462 6506-6507 6522-6523 6528-6529 6532 6534 6544 6555 6560 6562 6564 6567 6569 6571 6575 6582 6584 6589 6593 6626 6631-6632 6636 6640-6641 6643 6652 6743 6912 6928 6933 6976 6981 6992 7213 7226 7274 7311 7315 7319-7320 7323 7330 7335-7336 7339-7340 7361 8572 8575 8663 8670 8699 9031 9036 9048 9050 9057-9058 9065 9067 9069 9072 9084 9111 9161 9166 9172 9227 9231 9250-9252 9254-9255 9258 9261-9262 9265-9266 9272 9274 9341 9344 9347 9349 9351-9354 9361 9366 9368 9370 9377-9379 9381 9384 9389 9392 9468 9470-9471 9474 9480 9483 9504-9505 9507-9508 9519 9605-9606 9632 9634 9640 9784-9785 9810 9817 9849-9850 9877 9885-9886 9895 9933 9956 9983 9992 10017 10027 10061 10086 10092 10114 10120 10154 10182 10268-10269 10271 10296 10379 10396 10403 10422 10453 10459 10484 10547 10554 10623 10636 10638 10654 10657 10665 10673 10676-10677 10689 10691-10692 10696 10698 10703 10722 10741 10795 10861-10862 10869 10874 10911 10926 10932 10950 11004 11032 11048 11085 11090-11093 11178 11182 11282 11314 11325 11348 11362 11393 11403 11405 11433 11587 12375 12380 12382 12404 12408 12552 17743 17745 17751 17753 17776 18071-18072 18388 19091 19099-19100 19382 19390 22719 22760 23074 23101 23103 23146 23190-23191 23194 23203 23205 23208-23209 27257 27337 27420 28271 28280 28341 28363 28630 28636 30037 32429 32501 32508 32682 36725 49151https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/909/120?format=asciiOpticaldefaultJ/ApJ/909/120/table1*Close galaxy pairs and multiples in MaNGA integral field units (IFUs)SDSSSDSS name (JHHMMSS.ss+DDMMSS.s) in DR9meta.idcharrecnoRecord number assigned by the VizieR team.
