cds-question@unistra.frgalaxiesspectroscopyinteracting-galaxiesredshiftedinfrared-astronomysurveysWe identify a sample of spectroscopically measured emission line galaxy (ELG) Pairs up to z=1.6 from the Wide Field Camera 3 (WFC3) Infrared Spectroscopic Parallels (WISP) survey. WISP obtained slitless, near-infrared grism spectroscopy along with direct imaging in the J and H bands by observing in the pure-parallel mode with the WFC3 on board the Hubble Space Telescope. From our search of 419 WISP fields covering an area of ~0.5deg^2^, we find 413 ELG pair systems, mostly H{alpha} emitters. We then derive reliable star formation rates (SFRs) based on the attenuation-corrected H{alpha} fluxes. Compared to isolated galaxies, we find an average SFR enhancement of 40%-65%, which is stronger for major Pairs and Pairs with smaller velocity separations ({Delta}v<300km/s). Based on the stacked spectra from various subsamples, we study the trends of emission line ratios in pairs, and find a general consistency with enhanced lower ionization lines. We study the pair fraction among ELGs, and find a marginally significant increase with redshift f{propto}(1+z)^{alpha}^, where the power-law index {alpha}=0.58+/-0.17 from z~0.2 to ~1.6. The fraction of active galactic nuclei is found to be the same in the ELG Pairs as compared to the isolated ELGs.2021ApJ...923..156Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/923/156CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/617/240 : Oxygen abundances in the GOODS-N field (Kobulnicky+, 2004)J/ApJ/685/235 : Host and companion galaxies in the SDSS (Patton+, 2008)J/ApJ/697/1369 : GOODS Ks-selected multiwavelength compilation (Bundy+, 2009)J/MNRAS/489/2792 : Clumps and satellites impact on galaxy mass (Zanella+, 2019)http://wisps.ipac.caltech.edu/ : WFC3 IR Spectroscopic Parallel Survey homehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/923/156https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/923/156http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/923/156https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/923/156https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/923/156http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/923/156GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/923/156/elgp (Emission line galaxy pair (Table 1) and galaxy properties (Table 2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/923/156/elgp?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/923/156/elgp?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/923/156/elgp?GETtext/xml+votable180.050000true16.6713638915.151823060.0055555555555555566/524 826 2473 4376 4479 4775 4996 5072 5262 5274 5372 5413 5522 5570 5642 5698 5817 5855 5860 5876 5882 5967 5974 5985 6005 6007 6056 6106 6515 7176 7178 7190 7232 7254 7277 7763 8359 8440 8451 8469 8480 8559 8641 8838 8858 8867 8907 8915 8934 8952 9018 9026 9031 9038 9064 9117 9146 9174 9182 9305 9346 9440 9680 9705 9756 9783 9891 10144 10219 10251 10300 10312 10316 10336 10379 10405 10415 10418 10624 10659 10691 10724 10761 10789 10807 10911 10940 10986 11021 11157 11239 11326 11332 11406 11434 11452 11529-11530 11585 11596 11781 13643 16447 17215 17360 17498 17515 17703 17730 17746 17990 18302 18387 18902 19045 19776 19841 20125 21016 21432 22818 22974 23376 24859 25373 25932 25961 25964 26033 26045 26074 26097 26246 26249 26347 26350 26396 26423 26457 26858 26976 26995 27065 27116 27250 27295 27428 27486 27509 27515 27518 27526 27568 27574 27607 27646 27719 27742 27765 27781 27834 27964-27965 28154 28158 28232 28247 28401 28516 28546 31291 31466 31535 32999 34460 35198 35360 35542 35741 35913 35987 35993 36233 36275 36278 36313 36317 36802 38837 40213 43842 44016 44245 44542 45341 45701 46299 46399 46418 46424 46444 46555 47510 48290 49078 49094 49125https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/923/156?format=asciiInfrareddefaultJ/ApJ/923/156/elgpEmission line galaxy pair (Table 1) and galaxy properties (Table 2)recnoRecord number assigned by the VizieR team.
