cds-question@unistra.frgamma-ray-astronomyFrom past experiments the average power density spectrum (PDS) of gamma-ray bursts (GRBs) with unknown redshift was found to be modelled from 0.01 to 1Hz with a power law, f^-{alpha}^, with {alpha} broadly consistent with 5/3. Recent analysis of the Swift/Burst Alert Telescope (BAT) catalogue showed analogous results in the 15-150keV band. We carried out the same analysis on the bright GRBs detected by BeppoSAX/Gamma-ray Burst Monitor (GRBM) and Fermi/Gamma-ray Burst Monitor (GBM). The BeppoSAX/GRBM data, in the energy range 40-700keV and with 7.8 and 0.5ms time resolutions, allowed us to explore for the first time the average PDS at very high frequencies (up to 1kHz) and reveal a break around 1-2Hz, previously found in Compton Gamma Ray Observatory/Burst and Transient Source Experiment data. The Fermi/GBM data, in the energy band 8-1000keV, allowed us to explore for the first time the average PDS within a broad energy range. Our results confirm and extend the energy dependence of the PDS slope, according to which harder photons have shallower PDS.2013MNRAS.431.3608Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/431/3608CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/180/192 : BeppoSAX/GRBM {gamma}-ray Burst Catalog (Frontera+, 2009)J/ApJS/211/13 : The second Fermi/GBM GRB catalog (4yr) (von Kienlin+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/431/3608https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/431/3608http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/431/3608https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/431/3608https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/431/3608http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/431/3608GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/431/3608/Fermi (Time, Peak count rate and white noise level for the full Fermi sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/431/3608/Fermi?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/431/3608/Fermi?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/431/3608/Fermi?GETtext/xml+votable180.050000true188.1-60.20.005555555555555556Cone search capability for table J/MNRAS/431/3608/BeppoSAX (Time, Peak count rate and white noise level for the BeppoSAX/GRBM high-resolution sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/431/3608/BeppoSAX?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/431/3608/BeppoSAX?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/431/3608/BeppoSAX?GETtext/xml+votable180.050000true232.0619.60.0055555555555555566/240 598 646 1209 2025 2717 2875 2916 3051 3111 3586 3806 4099 4449 4487 4575 4690 4693 4711 4741 4862 5051 5153 5346 5530 5719 5756 5871 5907 6152 6261 6576 6683 6729 6734 6841 7332 7581 7789 7847 7886 8071 8603 8617 9060 9271 9278 9431 9827 9937 9984 10579 11209 11286 11545 11563 11812 11904 12170 12287-12288 12565 12826 13173 13191 13215 13559 14041 14059 14715 15071 15112 16037 16084 16186 16282 16292 16625 16661 16813 16893 17170 17269 17512 17701 17818 17944 18445 18457 18704 18777 18784 18901 19544 20077 20426 20453 20736 20941 21059 21284 21518 21521 21724 21737 21752 21816 21880 21963 22226 22281 22299 22665 22715 22838 23406 23423 23949 24068 24378 24426 24471 24642 24834 25070 25171 25552 25710 26111 26360 26365 27352 27713 27800 27812 27961-27962 27964 28123 28164 28692 28879 28930 28959 29265 29376 29449 29853 29920 30037 30139 30347 30595 30692 30872 31270 31547 32419 32579 32646 33050 33813 33922 33961 34302 35516 35633 35652 35721 35764 35769 35812 36442 36460 36726 36812 36851 36858 37294 37390 37440 37628 37900 37910 37935 38282 38388 38418 38944 38965 39521 39594 39695 39828 40167 40400 40461 40778 40952 41465 41775 42718 43045 43147 43498 43891-43892 44036 44202 44277 44311 44498 44889 45373 45401 45464 45483 45722 46215 46632 46710 46813 47116 47153 47201 47313 47427 47438 47443 47466 47623 48134 48557 48774 48934https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/431/3608?format=asciiGamma-raydefaultJ/MNRAS/431/3608/FermiTime, Peak count rate and white noise level for the full Fermi samplerecnoRecord number assigned by the VizieR team.
