DESCRIPTION:Speakers: Irene ARKHANGELSKAJA (National Research Nuclear Univ
 ersity MEPhI (Moscow Engineering Physics Institute))\nUsually two GRBs gro
 ups separated in duration distribution: short and long. These types events
  classified due analysis of duration of interval which the integrated coun
 ts from the GRB raise from $5\\%$ to $95\\%$ ($t_{90}$). The value $t_{90}
 ~\\sim~2$s used as boundary between short and long events. Firstly GRB dur
 ation distribution was analysed on data of BATSE experiment onboard the (C
 GRO) Compton Gamma Ray Observatory ($\\sim ~2700$ bursts) operated from Ap
 ril 1991 until to June 2000. However in 1999 third burst subgroup (interme
 diate GRBs) was found due GRBs duration and duration-hardness distribution
 s analysis of 4B current BATSE catalogue (recently available as 5B one) in
  interval 1~s~$\\le t_{90} \\le 40$~s.\n\nSince CGRO operation finished fi
 ve satellite experiments GRBs catalogues (Wind\, Suzaku\, RHESSI\, Swift/B
 AT and Fermi/GBM) contain sufficient amount of bursts for duration distrib
 ution precision investigation. The results of these distributions analysis
  are discussed. It allows concluding the appearance of intermediate GRB su
 bgroup on data of six experiments: BATSE/CGRO\, Wind\, Suzaku\, RHESSI\, S
 wift/BAT and Fermi/GBM.\n\nhttps://indico.particle.mephi.ru/event/4/contri
