DESCRIPTION:NGC6240: Triple supermassive black holes in simulation and obse
 rvation. Kozai-Lidov Effect and the timescale of PN merging. \nDr. Peter B
 erczyk\n\nOne of the possible ways of creating the supermassive black hole
  (SMBH) is hierarchical merging scenario. Central SMBHs at interacting and
  coalescing host-galaxies are observed as SMBH candidates at different sep
 arations from hundreds of pc to mpc. One of the strongest SMBHs candidates
  is ULIRG galaxy NGC6240 which was X-ray spatially and spectroscopically r
 esolved by Chandra. Researching of central SMBHs merging in dense stellar 
 environment allows to retrace their evolution from kpc to mpc scales. The 
 main goal of our dynamical modeling was to reach the gravitational wave (G
 W) emission regime for the multiple BHs model. We present the direct N-bod
 y simulations with up to one million particles and relativistic post-Newto
 nian corrections for the SMBHs particles up to 3.5PN. From our models we f
 ound the upper limit of merging time for NGC6240 central SMBHs is less tha
 n ~50 Myr.
