cds-question@unistra.frgamma-ray-astronomyWe analyzed the data obtained by the SPI telescope onboard the INTEGRAL observatory to search for short transient events with a duration from 1 ms to a few tens of seconds. An algorithm for identifying gamma-ray events against the background of a large number of charged particle interactions with the detector has been developed. The classification of events was made. Apart from the events associated with cosmic gamma-ray bursts (GRBs) confirmed by other space experiments and the activity of known soft gamma repeaters (for example, SGR 1806-20), previously unreported GRBs have been found. GRB candidates and short gamma-ray events probably associated with the activity of known SGRs and AXPs have been selected. The spectral evolution of 28 bright GRBs from the catalog has been studied extensively. A new method for investigating the spectral evolution is proposed. The energy dependence of the spectral lag for bursts with a simple structure of their light curves and for individual pulses of multipulse events is shown to be described by a logarithmic function, lag~Alog(E). It has been established that the parameter A depends on the pulse duration, with the dependence being universal for all of the investigated GRBs. No negative spectral lags have been detected for bursts with a simple structure of their light curves.2014AstL...40..235Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/40/271CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/528/A122 : SwiftFT catalog (Puccetti+, 2011)J/ApJS/195/2 : The second Swift BAT GRB catalog (BAT2) (Sakamoto+, 2011)J/ApJS/208/21 : The BATSE 5B GRB spectral catalog (Goldstein+, 2013)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/PAZh/40/271https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/40/271http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/40/271https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/40/271https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/40/271http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/40/271GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/40/271/table4 (Observed properties of the GRBs detected in the SPI/INTEGRAL experiment)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/40/271/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/40/271/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/40/271/table4?GETtext/xml+votable180.050000true74.387711120.48469390.0055555555555555566/3795 10411 10836 11008 12848 14563 15315 15739 20094 23585 24201 24219 26085 28849 29100 29225 29230 29318 29569 29862 29884 30203 30409 30557 32074 32239 32646 34816 35200 35485 37910 39327 41285 41467 42409 43101 44475 47397 48054https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/40/271?format=asciiGamma-raydefaultJ/PAZh/40/271/SGRsBursts of Soft {gamma}-ray Repetears (SGR) detected in SPI/INTEGRAL experimentrecnoRecord number assigned by the VizieR team.
