cds-question@unistra.frgalaxiesspectroscopyredshiftedgravitational-lensingWe present the catalogue of blended galaxy spectra from the Galaxy And Mass Assembly (GAMA) survey. These are cases where light from two galaxies are significantly detected in a single GAMA fibre. Galaxy pairs identified from their blended spectrum fall into two principal classes: they are either strong lenses, a passive galaxy lensing an emission-line galaxy; or occulting galaxies, serendipitous overlaps of two galaxies, of any type. Blended spectra can thus be used to reliably identify strong lenses for follow-up observations (high-resolution imaging) and occulting pairs, especially those that are a late-type partly obscuring an early-type galaxy which are of interest for the study of dust content of spiral and irregular galaxies. The GAMA survey setup and its AUTOZ automated redshift determination were used to identify candidate blended galaxy spectra from the cross-correlation peaks. We identify 280 blended spectra with a minimum velocity separation of 600km/s, of which 104 are lens pair candidates, 71 emission-line-passive pairs, 78 are pairs of emission-line galaxies and 27 are pairs of galaxies with passive spectra. We have visually inspected the candidates in the Sloan Digital Sky Survey (SDSS) and Kilo Degree Survey (KiDS) images. Many blended objects are ellipticals with blue fuzz (Ef in our classification). These latter 'Ef' classifications are candidates for possible strong lenses, massive ellipticals with an emission-line galaxy in one or more lensed images. The GAMA lens and occulting galaxy candidate samples are similar in size to those identified in the entire SDSS. This blended spectrum sample stands as a testament of the power of this highly complete, second-largest spectroscopic survey in existence and offers the possibility to expand e.g. strong gravitational lens surveys.2015MNRAS.449.4277Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/449/4277CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/413/971 : Galaxy And Mass Assembly (GAMA) DR1 (Driver+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/449/4277https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/449/4277http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/449/4277https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/449/4277https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/449/4277http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/449/4277GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/449/4277/table3 (The complete catalogue of blended spectra in the GAMA survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/449/4277/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/449/4277/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/449/4277/table3?GETtext/xml+votable180.050000true129.01621-0.693360.0055555555555555565/5461 6399 6487 6491 6513 6568 6740-6742 6827 6/4097 4099-4101 4105-4106 8202 16546 17492-17493 17503 17675-17676 17682-17685 17689 17691 17693-17694 17698 17700-17701 17703 17708 17712 21837 21839 21842-21843 21850 21852 21854-21855 21872-21873 21875-21877 21884 25588-25589 25591 25593-25594 25915-25917 25931 25934-25937 25939-25940 25944-25945 25952-25954 25956-25957 25962-25963 25970-25971 25974-25976 26004-26006 26048 26051 26064 26250-26252 26254-26255 26277-26278 26280 26282 26284-26285 26287-26288 26291 26949 26951 26959 26973-26974 26993-26995 27278-27279 27290 27297-27300 27304-27306 27312 27314-27315 27318 27320-27322 27324 27648-27650 27652-27653 27656 36780 36782 36798 40951 40956-40958 46571 46575 46580 46583 46586 46915 46921 46924 46926 46929 46932 46936 46947 46950https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/449/4277?format=asciiOpticaldefaultJ/MNRAS/449/4277/table3The complete catalogue of blended spectra in the GAMA surveyFieldField designationobs.fieldcharrecnoRecord number assigned by the VizieR team.
