Numerical Simulations of NGC 4038/9

John Hibbard, NRAO

Josh Barnes, IfA

WORK IN PROGRESS!

---

• Presentations from 203rd AAS (Jan 8-9, 2004)
  • The Antennae Galaxies: Archetype for Colliding Galaxies (pdf file of press conference presentation by J. Hibbard) (1.8 MB)
  • "Fact Sheet" from press conference (Jan 8th 2004)
  • The Antennae Galaxies: Archetype for Colliding Galaxies (pdf file of invited review by J. Hibbard at special topical session on The Antennae, Jan 9 2004) (4.6 MB)
• Most Recent Match to NGC 4038/9 data
  • preliminary match
  • Omega trade study (iN=60, iS=20)
  • Inclination trade study (wN=-60, wS=120)
  • most recent match (70,-60) (30,120)
  • movie of most recent match (70,-60) (30,120) (N=70k)
  • rotation of most recent match (70,-60) (30,120) (N=70k)
  • movie of 1mill realization of most recent match (70,-60) (30,120) (N=1E6)
  • Geometry from tails
• earlier mpg Video from Josh Barnes
• John Dubinski's simulation of The Antennae

Status Feb. 2004: want to play with internal structure of galaxies to see if we can get better match to inner morphology ("Ring-hook"), and reduce velocity of N.tail.
