cds-question@unistra.frgamma-ray-astronomyx-ray-sourcesWe present a comprehensive statistical analysis of Swift X-ray light curves of gamma-ray bursts (GRBs) collecting data from more than 650 GRBs discovered by Swift and other facilities. The unprecedented sample size allows us to constrain the rest-frame X-ray properties of GRBs from a statistical perspective, with particular reference to intrinsic time-scales and the energetics of the different light-curve phases in a common rest-frame 0.3-30keV energy band. Temporal variability episodes are also studied and their properties constrained. Two fundamental questions drive this effort: (i) Does the X-ray emission retain any kind of 'memory' of the prompt {gamma}-ray phase? (ii) Where is the dividing line between long and short GRB X-ray properties? We show that short GRBs decay faster, are less luminous and less energetic than long GRBs in the X-rays, but are interestingly characterized by similar intrinsic absorption. We furthermore reveal the existence of a number of statistically significant relations that link the X-ray to prompt {gamma}-ray parameters in long GRBs; short GRBs are outliers of the majority of these two-parameter relations. However and more importantly, we report on the existence of a universal three-parameter scaling that links the X-ray and the {gamma}-ray energy to the prompt spectral peak energy of both long and short GRBs: E_X,iso_{prop.to}E^1.00+/-0.06^_{gamma},iso_/E^0.60+/-0.10^_pk_.2013MNRAS.428..729Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/428/729CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/510/A48 : Palermo Swift-BAT Hard X-ray Catalogue (Cusumano+, 2010)J/A+A/551/A142 : 7 year Swift-XRT point source catalog (1SWXRT) (D'Elia+, 2013https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/428/729https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/428/729http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/428/729https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/428/729https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/428/729http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/428/729GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/428/729/observed (Best-fitting parameters in the observer frame)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/428/729/observed?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/428/729/observed?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/428/729/observed?GETtext/xml+votable180.050000true100.1975-37.07290.0055555555555555566/186 205 314 338 393 453 462 500 503 550 646 699 877 908 918 923 1507 1526 1652 2044 2296 2315 2357 2456 2538 2735 2793 2925 2938 3038 3405 3506 3536 3551 3586 3589 3611 3659 3700 3706 3832 3894 3927 4026 4323 4450 4485 4788 4955 4977 5051 5080 5376 5493 5525 5618 5625 5633 5726 5745 5840 5941 5987 6004 6102 6258 6261 6404 6593 6862 7043-7044 7156 7184 7518 7685 7747 7908 8375 8569 8641 8669 8761 8798 8932 8954 9024 9069 9100 9143 9330 9370 9395 9431 9682 9714 9750 9914 9926 9989 10094 10135 10335 10445 10447 10519 10666 10680 10723 10762 10852 10912 10914 10948 11248 11307 11640 11649 11657 11673 11749 11756 11905 12020 12134 12287 12597 12848 13191 13312 13331 13475 13558 13694 13701 13787 13898 13924 14059 14248 14259 14272 14588 14754 14781 14846 14852 14892 14977 15004 15054 15292 15315 15348 15473 15595 15613 15615 15683 15702 15874 15915 15995 16072 16078 16172 16232 16282 16292 16489 16493 16546 16661 16769 16991 17279 17316 17411 17453 17561 17721 17733 17749 17814 17980 18097 18221 18264 18494 18681 18777 18910 18915 18978 19049 19102 19164 19168 19194 19293 19331 19544 19731 19865 19890 19911 20030 20053 20191 20263 20360 20401 20655 20668 20753 21137 21284 21360 21439 21498 21688 21903 21915 21962 22129 22157 22422 22580 22590 22624 22916 23138 23585 23680 24036 24105 24424 25120 25174 25293 25312 25394 25529 25597 25761 25901 25946 26036 26441 26503 26671 27085 27289 27566 27841 27906 27911 27933 27961-27962 28063 28202 28311 28467 28630 28726 28863 28948 29019 29563 29612 29884 30385 30461 30553 30557 30568 30678 30692 31143 31185 31281 31385 31494 31583 31607 31700 31730 31847 31934 31982 32110 32239 32646 32676 32713 32880 33004 33195 33278 33323 33482 33525 33617 33679 33735 33813 33845 34147 34435 34440 34465 34605 34788 34949 35045 35088 35330 35566 35569 35615 35633 35844 36074 36297 36374 36460 36528 37007 37139 37351 37383 37428 37562 37628 37830 37910 38046 38280 38301 38926 39008 39059 39076 39199 39213 39224 39374 39432 39475 39553 39594 39630 39829 39881 39912 40167 40249 40272 40389 40433 40482 40611 40642 40778 41020 41059 41135 41442 41547 41555 41989 42144 42319 42473 42865 42914 42952 43045 43280 43558 43920 44021-44022 44160 44212 44419 44493 44720 44822 44857 44861 45008 45088 45180 45205 45361 45401-45402 45409 45422 45483 45510 45561 45777 45836 45938 46022 46218 46250 46510 46594 46814 47031 47117 47162 47251 47436 47459 47632 47911 47945 47991 48007 48054 48189 48422 48447 48458 48771 49004https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/428/729?format=asciiGamma-rayX-raydefaultJ/MNRAS/428/729/observedBest-fitting parameters in the observer frameGRBGRB name (YYMMDDA)meta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
