In this work, we present "isolated" galaxies, which are defined as having no spectroscopically identified galaxy within a projected distance of 100kpc and a line of sight velocity separation of 500km/s. We standardized all galaxy properties to the {Lambda}CDM cosmology and galaxy luminosities, absolute magnitudes, and rest-frame colors to the B- and K-band on the AB system. We present galaxy properties and rest-frame MgII equivalent width, W_r_(2796), versus galaxy redshift. The well-known anti-correlation between W_r_(2796) and quasar-galaxy impact parameter, D, is significant to the 8{sigma} level. The mean color of MAGIICAT galaxies is consistent with an Sbc galaxy for all redshifts. We also present B- and K-band luminosity functions for different W_r_(2796) and redshift subsamples: "weak absorbing" [W_r_(2796)&lt;0.3{AA}], "strong absorbing" [W_r_(2796)&gt;=0.3{AA}], low redshift (z{&lt;}&lt;z&gt;), and high redshift (z{&gt;=}&lt;z&gt;), where &lt;z&gt; = 0.359 is the median galaxy redshift. Rest-frame color B-K correlates with M_K_ at the 8{sigma} level for the whole sample but is driven by the strong absorbing, high-redshift subsample (6{sigma}). Using M_K_ as a proxy for stellar mass and examining the luminosity functions, we infer that in lower stellar mass galaxies, MgII absorption is preferentially detected in blue galaxies and the absorption is more likely to be weak.</description><source format="bibcode">2013ApJ...776..114N</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/776/114</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/546/A67">J/A+A/546/A67 : Catalog of strong MgII absorbers (Lawther+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/754/38">J/ApJ/754/38 : MgII absorption systems for FSRQs (Chand+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/748/131">J/ApJ/748/131 : MgII absorbers in SDSS-DR7 quasar catalog (Shen+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/727/47">J/ApJ/727/47 : The MgII cross-section of red galaxies (Bowen+, 2011)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/724/L176">J/ApJ/724/L176 : MgII absorbing gas around galaxies (Chen+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/714/1521">J/ApJ/714/1521 : Spectroscopy of galaxies around distant QSOs (Chen+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/698/819">J/ApJ/698/819 : MgII and LRGs cross-correlation analysis (Lundgren+, 2009)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/679/239">J/ApJ/679/239 : Associated MgII absorbers (Vanden+, 2008)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/660/1093">J/ApJ/660/1093 : Weak MgII absorbers at 0.4&lt;z&lt;2.4 (Narayanan+, 2007)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/639/766">J/ApJ/639/766 : SDSS-DR3 strong MgII absorbers (Prochter+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/371/495">J/MNRAS/371/495 : Catalog of 1806 MgII absorbers from SDSS DR3 (Bouche+, 2006)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/354/L25">J/MNRAS/354/L25 : MgII absorbers in SDSS QSOs (Bouche+, 2004)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/410/33">J/A+A/410/33 : MgII/FeII absorbers in 2dF-quasar survey (Menard+, 2003)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/559/654">J/ApJ/559/654 : Ly{alpha} absorption systems.
