cds-question@unistra.frgamma-ray-astronomygamma-ray-burstsWe analyze pulse properties of short gamma-ray bursts (GRBs) from a new catalog containing 434 pulses from 387 BATSE time-tagged event (TTE) GRBs. Short GRB pulses exhibit correlated properties of duration, fluence, hardness, and amplitude, and they evolve hard to soft while undergoing similar triple- peaked light curves similar to those found in long/intermediate bursts. We classify pulse light curves using their temporal complexities, demonstrating that short GRB pulses exhibit a range of complexities from smooth to highly variable. Most of the bright, hard, chaotic emission seen in complex pulses seems to represent a separate highly variable emission component. Unlike long/intermediate bursts, as many as 90% of short GRBs are single-pulsed. However, emission in short multipulsed bursts is coupled such that the first pulse's duration is a predictor of both the interpulse separation and subsequent pulse durations. These results strongly support the idea that external shocks produce the prompt emission seen in short GRBs. The similarities between the triple-peaked structures and spectral evolution of long, short, and intermediate GRBs then suggests that external shocks are responsible for the prompt emission observed in all GRB classes. In addition to these findings, we identify a new type of gamma-ray transient in which peak amplitudes occur at the end of the burst rather than at earlier times. Some of these "crescendo" bursts are preceded by rapid-fire "staccato" pulses, whereas the remaining are preceded by a variable episode that could be unresolved staccato pulses.2018ApJ...855..101Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/855/101CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/508/314 : Gamma-ray bursts types (Mukherjee+, 1998)J/ApJ/720/1146 : Spectral analysis of GRBs (Lu+, 2010)J/ApJ/740/104 : BATSE GRB pulse catalog - preliminary data (Hakkila+, 2011)J/ApJ/777/132 : A search for progenitors of short GRBs (Dichiara+, 2013)J/ApJS/208/21 : The BATSE 5B GRB spectral catalog (Goldstein+, 2013)J/ApJS/227/7 : Long & short GRBs with host galaxies data (Li+, 2016)http://gammaray.msfc.nasa.gov/batse/grb/catalog/current/ : Gamma-rayhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/855/101https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/855/101http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/855/101https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/855/101https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/855/101http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/855/101GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/855/101/catalog (BATSE time-tagged event (TTE) GRB pulse catalog (tables 5-7))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/855/101/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/855/101/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/855/101/catalog?GETtext/xml+votable180.050000true114.48-25.310.0055555555555555566/49 275 526 559 920 983 1127 1348 1604 1723 1738 1746 1844 1847 2039 2238 2444 2566 2957 2977 3119 3131 3150 3279 3456 3646 3680 3737 3844 3865 3911 3962 4069 4121 4192 4278 4358 4565 4915 5047 5171 5195 5298 5418 5521 5572 5631 5901 6056 6387 6545 6622 6756 6880 7249 7415 7424 7721 7812 7841 7871 7991 8029 8169 8197 8224 8310 8550 8607 8623 8708 8827 8859 9377 9534 9565 9678 10195 10336 10513 10619 10622 10667 10720 10741 10815 10981 11054 11111 11188 11198 11337 11591 11620 11638 11661 11751 11946 12009 12028 12086 12267 12269 12280 12329 12618 12713 12734 12951 13202 13275 13478 13560 13650 13861 13953 13960 14021 14052 14128 14319 14703 15015 15257 15311 15341 15519 15568 15659 15728 16039 16152 16521 16697 16759 16818 17302 17527 17537 17816 17902 18060 18064 18175 18195 18226 18409 18706 18747 18770 18970 19040 19464 20268 20366 20928 20965 20981 21027 21100 21370 21536 21651 21721 21733 21840 21970 22063 22186 22216 22397 22532 22627 23009 23129 23150 23152 23329 23345 23373 23552 23614 23616 23670 23880 24115 24125 24180 24247 24296 24358 24408 24437 24475 24546 24618 25135 25303 25538 25545 25601 25668 25789 25826 25903 26056 26383 26562 26645 27030 27322 27460 27549 27630 27704 27711 28138 28492 28570 28627 28908 29105 29225 29260 29308 29735 29857 30034 30163 30340 30345 30349 30418 30543 30548 30745 30828 30862 31083 31183 31214 31237 31277 31342 31586 31783 32024 32062 32142 32727 32827 32863 32878 32912 32984 33076 33133 33214 33386 33423 33433 33499 34124 34129 34244 34469 34501 34523 34550 34828 34858 34985 35218 35236 35301 35346 35435 35571 35914 35994 36247 36308 36551 36585 36587 36769 37228 37240 37256 37410 37447 37663 37760 37778 37799 38029 38079 38230 38345 38415 38565 38678 38723 38727 38767 38772 38815 39149 39310 39372 39463 39896 39988 40034 40141 40461 40486 40716 40753 40814 41059 41069 41079 41147 41349 41442 41682 41995 42038 42205 42232 42325 42595 42959 43011 43190 43341 43428 43484 43545 43805 43929 43972 44214 44298 44383 44384 44564 44567 44681 44727 44959 45057 45167 45198 45349 45458 45560 45567 45675 45937 46202 46259 46274 46306 46441 46503 46511 46931 47203 47216 47284 47382 47399 47411 47470 47498 47544 47708 47750 47816 48426 48430 48769 49109 49143https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/855/101?format=asciiGamma-raydefaultJ/ApJ/855/101/catalogBATSE time-tagged event (TTE) GRB pulse catalog (tables 5-7)4BrDisplay data from the BATSE 4Br (Paciesas+, 1999, IX/20)meta.ref.urlintnullablee_tau-pk[0/3849000] Uncertainty in tau-pksstat.errordoublerecnoRecord number assigned by the VizieR team.
