cds-question@unistra.frgamma-ray-astronomyThe short duration (T90<2s) gamma-ray bursts (GRBs) detected in the SPI-ACS experiment onboard the INTEGRAL observatory are investigated. Averaged light curves have been constructed for various groups of events, including short GRBs and unidentified short events. Extended emission has been found in the averaged light curves of both short GRBs and unidentified short events. It is shown that the fraction of the short GRBs in the total number of SPI-ACS GRBs can range from 30 to 45%, which is considerably larger than has been thought previously.2010PAZh...36..744Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/36/744CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/438/1175 : First INTEGRAL SPI-ACS Gamma-Ray Burst Catalogue (Rau+, 2005)J/A+A/498/399 : GRB observed with RHESSI satellite (Ripa+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/36/744https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/36/744http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/36/744https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/36/744https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/36/744http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/36/744GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapGamma-raydefaultJ/PAZh/36/744/table2*Catalog of confirmed short GRBs detected with SPI-ACS/INTEGRALn_T90[* ] Origin of T90 (1)meta.notecharGRBGRB namemeta.id;meta.mainintrecnoRecord number assigned by the VizieR team.
