cds-question@unistra.frgamma-ray-astronomygamma-ray-burstsastronomical-modelsWe present compelling evidence that most gamma-ray burst (GRB) pulse light curves can be characterized by a smooth single-peaked component coupled with a more complex emission structure that is temporally symmetric around the time of the pulse peak. The model successfully fits 86% of Burst and Transient Source Experiment GRB pulses bright enough for structural properties to be measured. Surprisingly, a GRB pulse's light-curve morphology can be accurately predicted by the pulse asymmetry and the stretching/compression needed to align the structural components preceding the temporal mirror with the time- reversed components following it. Such a prediction is only possible because GRB pulses exhibit temporal symmetry. Time-asymmetric pulses include fast rise exponential decays, rollercoaster pulses, and asymmetric u-pulses, while time-symmetric pulses include u-pulses and crowns. Each morphological type is characterized by specific asymmetries, stretching parameters, durations, and alignments between the smooth and structured components, and a delineation in the asymmetry/stretching distribution suggests that symmetric pulses and asymmetric pulses may belong to separate populations. Furthermore, pulses belonging to the short GRB class exhibit similar morphologies to the long GRB class, but appear to simply occur on shorter timescales.2021ApJ...919...37Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/919/37CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/20 : The Fourth BATSE Burst Revised Catalog (Paciesas+ 1999)J/ApJ/740/104 : BATSE GRB pulse catalog - preliminary data (Hakkila+, 2011)J/ApJ/744/141 : Shapes of GRB light curves (Bhat+, 2012)J/ApJ/748/134 : Variability components in BATSE GRB light curves (Gao+, 2012)J/ApJ/855/101 : BATSE TTE GRB pulse catalog (Hakkila+, 2018)http://heasarc.gsfc.nasa.gov/docs/cgro/batse/ : BATSE on Heasarchttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/919/37https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/919/37http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/919/37https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/919/37https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/919/37http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/919/37GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/919/37/table2 (BATSE GRB time-reversed pulse and morphology catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/919/37/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/919/37/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/919/37/table2?GETtext/xml+votable180.050000true270.67524.76670.0055555555555555566/134 400 464 532 908 920 955 1038 1109 1553 1734 1831 2038 2130 2240 2254 2977 3441 3477 3520 3747 3842 3852 3893 3988 4102 4155 4217 4469 4571 5047 5130 5163 5178 5183 5195 5498 5637 5738 5751 5844 5901 5912 6395 6549 6752 6889 7049 7247 7249 7268 7325 7617 7624 7692 7749 7799 7871 8042 8055 8131 8310 8370 8385 8466 8485 8859 8981 9076 9117 9298 9420 9565 9645 9693 9741 9749 9778 9782 9921 10108 10195 10481 10532 10630 10982 11080 11111 11454 11577 11667 11751 12277 12345 12415 12485 12537 12739 12825 12879 12925 13220 13238 13260 13275 13351 13359 13404 13556 13591 13650 13832 14051 14128 14148 14159 14287 14330 14444 14608 14616 14670 14848 15043 15152 15160 15167 15311 15461-15462 15478 15733 15914 16014 16307 16521 16752 17017 17080 17658 17724 17786 17818 18085 18097 18226 18570 18581 18664 18767 18770 18922 19286 19442 19613 19739 19829 19895 20102 20127 20146 20183 20268 20450 20724 20755 21145 21199 21370 21651 21694 21859 21970 22128 22274 22411 22485 22784 23096 23308 23345 23442 23786 23937 24049 24296 24358 24570 24948 25160 25233 25473 25607 25774 25877 26182 26927 27025 27394 27400 27410 27495 27524 27745 27882 28014 28508 28827 28874 29062 29073 29105 29420 29455 29612 29808 29857 29893 29998 30429 30674 30775 30790 30845 30862 30993 31253 31295 31580 31666 31689 31955 31991 32062 32111 32287 32538 32688 32928 33049 33174 33386 33433 33476 33546 33713 33729 33922 33976 34003 34129 34259 34483 34555 34807 34858 35002 35081 35096 35123 35301 35578 35593 35602 35620 35899 35901 36068 36194 36243 36377 36476 36669 36781 36900 36938 37054 37152 37199 37295 37323 37393 37447 37560 37613 37829 38029 38388 38537 38633 38723 39128 39187 39295 39297 39445 39696 39724 39831 39858 39884 39896 39932 39951 39988 39999 40092 40132 40301 40362 40404 40486 40530 40592 40788 41077 41229 41241 41426 41596 41686 41773 42106 42115 42297-42298 42386 42817 42959 42962 43116 43187 43190 43254 43311 43322 43341 43363 43513 43777 43885 44564 44652 44727 44813 44831 44855 45101 45128 45346 45390 45677 45768 45962 45972 46024 46065 46247 46253 46255 46263 46286 46408 46541 46765 46872 46896 47171 47185 47316 47382 47416 47426 47512 47708 47951 47985 48219 48239 48266 48809 48922 48984https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/919/37?format=asciiGamma-raydefaultJ/ApJ/919/37/table2BATSE GRB time-reversed pulse and morphology catalogTrigNo[105/7575] BATSE trigger numbermeta.id;meta.mainintprimarym_TrigNo[p1-p3 ] Pulse name within BATSE trigger numbermeta.code.multipcharrecnoRecord number assigned by the VizieR team.
