PS1 photometry of 2863 ICRF3 quasars J/AJ/162/21 ivo://CDS.VizieR/J/AJ/162/21 doi:10.26093/cds/vizier.51620021 CDS Berghea C.T. Makarov V.V. Quigley K.

A dedicated method based on the Functional Principal Component Analysis is developed for these sparse and irregularly sampled data. With certain regularization and normalization constraints, it allows us to obtain uniform and compatible estimates of the variability amplitudes and average magnitudes between the passbands and objects. We find that the starting assumption of affinity of the light curves for a given object at different wavelengths is violated for several percent of the sample. The distributions of rms variability amplitudes are strongly skewed toward small values, peaking at ~0.1mag with tails stretching to 2mag. Statistically, the lowest variability is found for the r band and the largest for the reddest y band. A small "brighter-redder" effect is present, with amplitudes in y greater than amplitudes in g in 57% of the sample. The variability versus redshift dependence shows a strong decline with z toward redshift 3, which we interpret as the time dilation of the dominant time frequencies. The colors of radio-loud ICRF3 quasars are correlated with redshift in a complicated, wavy pattern governed by the emergence of brightest emission lines within the five passbands. 2021AJ....162...21B https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/162/21 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to I/337 : Gaia DR1 (Gaia Collaboration, 2016) J/AJ/121/2308 : Sloan Digital Sky Survey quasar photometry (Richards+, 2001) J/ApJ/633/638 : Variable quasar sample from SDSS (Wilhite+, 2005) J/ApJ/750/99 : The Pan-STARRS1 photometric system (Tonry+, 2012) J/ApJ/698/895 : Variations in QSOs optical flux (Kelly+, 2009) J/ApJ/835/L30 : Dislodged AGNs (Makarov+, 2017) J/MNRAS/467/L71 : Significance of VLBI/Gaia position offsets (Petrov+, 2017) J/ApJ/873/132 : ICRF3 radio-loud quasars with Gaia DR2 data (Makarov+, 2019) J/MNRAS/485/1822 : AGN core shift measurements (Plavin+, 2019) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/162/21 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/162/21 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/162/21 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/162/21 https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/162/21 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/162/21 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/AJ/162/21/table1 (Catalog of ICRF3 variability parameters) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/162/21/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/162/21/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/162/21/table1?
