cds-question@unistra.frgalaxiesphotometryinfrared-photometryThe Euclid Early Release Observations (ERO) programme targeted the Perseus galaxy cluster in its central region over 0.7deg^2^. We combined the exceptional image quality and depth of the ERO Perseus with FUV and NUV observations from GALEX and AstroSat/UVIT, as well as with ugrizHa data from MegaCam at the CFHT, to deliver FUV-to-NIR magnitudes of the 87 brightest galaxies within the Perseus cluster. We reconstructed the star-formation history (SFH) of 59 early-type galaxies (ETGs) within the sample, through the spectral energy distribution (SED) fitting code CIGALE and state-of-the-art stellar population (SP) models to reproduce the galactic UV emission from hot, old, low-mass stars (i.e. the UV upturn). In addition, for the six most massive ETGs in Perseus [stellar masses log(Mstellar/M_{sun}_)>=10.3], we analysed their spatially resolved SP and SFH through a radial SED fitting. In agreement with our previous work on Virgo ETGs, we found that (i) the majority of the analysed galaxies needs the presence of an UV upturn component to explain their FUV emission, with average temperatures <T_UV_>~33800K; (ii) the ETGs of Perseus have grown their stellar masses quickly, with star- formation timescales tau<~1500Myr. We found that all ETGs in the sample have formed more than about 30% of their stellar masses at z~5, up to extreme fractions of ~100%. At z~5, the stellar masses of the most massive nearby ETGs, which have present-day stellar masses log(M*/M_{sun}_)>10.8, are then found to be comparable to those of the red quiescent galaxies observed by JWST at similar redshifts (z>4.6). This study can be extended to ETGs in the 14000 deg2 extragalactic sky that will soon be observed by Euclid, in combination with those from other major upcoming surveys (e.g. Rubin/LSST), and other UV observations, to ultimately assess whether the massive ETGs that we observe today represent the progeny of the massive high-z JWST red quiescent galaxies.2026A&A...708A..63Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/708/A63CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/708/A63https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/708/A63http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/708/A63https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/708/A63https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/708/A63http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/708/A63GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/708/A63/tableb1 (GALEX and AstroSat/UVIT photometry of galaxies in the Perseus cluster)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/708/A63/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/708/A63/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/708/A63/tableb1?GETtext/xml+votable180.050000true50.091912141.6409150.0055555555555555566/1700-17012.1254112057198488e-19 1.4134638842407062e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/708/A63?format=asciiInfrareddefaultJ/A+A/708/A63/tableb1GALEX and AstroSat/UVIT photometry of galaxies in the Perseus clusterrecnoRecord number assigned by the VizieR team.
