cds-question@unistra.frgamma-ray-astronomyx-ray-sourcesredshiftedGamma-ray bursts (GRBs), which have been observed up to redshifts z~9.5, can be good probes of the early universe and have the potential to test cosmological models. Dainotti's analysis of GRB Swift afterglow light curves with known redshifts and a definite X-ray plateau shows an anti-correlation between the rest-frame time when the plateau ends (the plateau end time) and the calculated luminosity at that time (or approximately an anti-correlation between plateau duration and luminosity) (Dainotti+ 2008MNRAS.391L..79D, 2010ApJ...722L.215D). Here, we present an update of this correlation with a larger data sample of 101 GRBs with good light curves. Since some of this correlation could result from the redshift dependences of these intrinsic parameters, namely, their cosmological evolution, we use the Efron-Petrosian method to reveal the intrinsic nature of this correlation. We find that a substantial part of the correlation is intrinsic and describe how we recover it and how this can be used to constrain physical models of the plateau emission, the origin of which is still unknown. The present result could help to clarify the debated nature of the plateau emission.2013ApJ...774..157Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/774/157CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/209/20 : Swift GRB catalog with X-ray data (Grupe+, 2013)J/MNRAS/428/729 : GRB Swift X-ray light curves analysis (Margutti+, 2013)J/other/Sci/338.1445 : Relativistic jets from BH systems (Nemmen+, 2012)J/A+A/547/A57 : Swift X-ray Telescope Cluster Survey (Tundo+, 2012)J/A+A/528/A122 : SwiftFT catalog (Puccetti+, 2011)J/MNRAS/418/2202 : Analysis of {gamma}-ray bursts (Dainotti+, 2011)J/ApJS/195/2 : The second Swift BAT GRB catalog (BAT2) (Sakamoto+, 2011)J/ApJ/711/495 : Durations of Swift/BAT GRBs (Butler+, 2010)J/MNRAS/397/1177 : Swift-XRT observations of GRBs (Evans+, 2009)J/ApJ/609/935 : Gamma-ray burst formation rate (Yonetoku+, 2004)http://www.mpe.mpg.de/~jcg/grbgen.html : List of GRBs with coordinates; andhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/774/157https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/774/157http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/774/157https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/774/157https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/774/157http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/774/157GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/774/157/table1 (Fitting parameters of the analyzed GRB X-ray afterglows)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/774/157/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/774/157/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/774/157/table1?GETtext/xml+votable180.050000true306.475417-42.6006080.0055555555555555566/314 393 500 503 646 699 923 3111 3536 3586 4323 4450 4955 5051 5625 5633 5941 6261 7182 7227 7518 8074 8798 8932 9100 9370 10335 10447 10852 11657 11673 11905 12134 12597 13312 13694 13924 14259 16282 16991 17316 17411 17721 17814 18494 18681 18777 18978 19168 19731 19890 19911 20191 21962 23138 25761 25901 25946 26671 27085 27289 27566 27906 27933 27962 28063 31281 31385 31494 31583 32110 32239 33278 33679 34440 34949 35569 36074 36297 36374 36460 38280 38926 39076 40433 40778 44022 44212 44857 45008 45205 45361 45938 46022 46510 47162 47436 47459 47991 48458 49004https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/774/157?format=asciiGamma-rayX-rayOpticaldefaultJ/ApJ/774/157/table1Fitting parameters of the analyzed GRB X-ray afterglowsGRBGRB identifiermeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
