cds-question@unistra.frgalaxiesphotometrygalaxy-classification-systemshst-photometryredshiftedUsing Hubble Space Telescope (HST)/Advanced Camera for Surveys (ACS) slitless grism spectra from the PEARS program, we study the stellar populations of morphologically selected early-type galaxies in the GOODS North and South fields. The sample - extracted from a visual classification of the (v2.0) HST/ACS images and restricted to redshifts z>0.4 - comprises 228 galaxies (i_F775W_<24mag, AB) out to z<~1.3 over 320arcmin^2^, with a median redshift z_M_=0.75. This work significantly increases our previous sample from the GRAPES survey in the HUDF (18 galaxies over ~11arcmin^2^). The grism data allow us to separate the sample into "red" and "blue" spectra, with the latter comprising 15% of the total. Three different grids of models parameterizing the star formation history are used to fit the low-resolution spectra.2009ApJ...706..158Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/706/158CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/695/1591 : Spectrophotometry in PEARS fields (Pirzkal+, 2009)J/AJ/135/1624 : PEARS emission-line galaxies (Straughn+, 2008)J/ApJ/666/863 : GOODS MIPS early-type galaxies (Van Der Wel+, 2007)J/ApJ/650/148 : GOODS blue early-type galaxies (Lee+, 2006)J/ApJ/635/243 : Sample of GOODS/CDFS early-type galaxies (Ferreras+, 2005)J/AJ/129/2138 : Centers of early-type galaxies with HST (Lauer+, 2005)J/AJ/127/131 : NICMOS early-type galaxies (Stanford+, 2004)http://archive.stsci.edu/prepds/pears/ : PEARS (Probing Evolution Andhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/706/158https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/706/158http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/706/158https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/706/158https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/706/158http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/706/158GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/706/158/catalog (Catalog of PEARS early-type galaxies: observed data and physical properties in chemical enrichment (CSP) model)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/706/158/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/706/158/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/706/158/catalog?GETtext/xml+votable180.050000true189.111694262.25005310.0055555555555555566/11252 35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/706/158?format=asciiOpticaldefaultJ/ApJ/706/158/catalogCatalog of PEARS early-type galaxies: observed data and physical properties in chemical enrichment (CSP) modelzRedshiftsrc.redshiftfloatRePProjected half-light radiuskpcphys.angSize;srcfloatrecnoRecord number assigned by the VizieR team.
