cds-question@unistra.frgalaxiesphotometryultraviolet-sourcesredshiftedThis paper presents a search for high redshift galaxies from the Euclid Early Release Observations program `Magnifying Lens.' The 1.5deg2 area covered by the twin Abell lensing cluster fields is comparable in size to the few other deep near-infrared surveys such as COSMOS, and so provides an opportunity to significantly increase known samples of rare UV-bright galaxies at z=6-8 (M_UV_<-22). Beyond their still uncertain role in reionisation, these UV-bright galaxies are ideal laboratories from which to study galaxy formation and constrain the bright-end of the UV luminosity function. Of the 501994 sources detected from a combined YE, JE, and HE NISP detection image, 168 do not have any appreciable VIS/IE flux. These objects span a range in spectral colours, separated into two classes: 139 extremely red sources; and 29 Lyman-break galaxy candidates. Best-fit redshifts and spectral templates suggest the former is composed of both z>5 dusty star-forming galaxies and z=1-3 quiescent systems. The latter is composed of more homogeneous Lyman-break galaxies at z=6-8. In both cases, contamination by L- and T-type dwarfs cannot be ruled out with Euclid images alone. Additional contamination from instrumental persistence is investigated using a novel time series analysis. This work lays the foundation for future searches within the Euclid Deep Fields, where thousands more z>6 Lyman-break systems and extremely red sources will be identified.2025A&A...697A..16Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/697/A16CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/697/A16https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/697/A16http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/697/A16https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/697/A16https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/697/A16http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/697/A16GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/697/A16/tableb1 (Extremely red source candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/697/A16/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/697/A16/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/697/A16/tableb1?GETtext/xml+votable180.050000true328.2568480617.153556940.005555555555555556Cone search capability for table J/A+A/697/A16/tablea1 (Lyman-break galaxy candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/697/A16/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/697/A16/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/697/A16/tablea1?GETtext/xml+votable180.050000true328.3421080617.264356110.0055555555555555566/12597 12599 12640 12642 35341 353431.1144155533189453e-19 1.8281296955425429e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/697/A16?format=asciiEUVdefaultJ/A+A/697/A16/tableb1Extremely red source candidatesIdObject identifiermeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
