My Research Interests

Galaxy Interaction and Infrared Luminous Starburst Galaxies



• HI Streamers around M82: Tidally Disrupted Outer Gas Disk (Yun, M.S., Ho, P.T.P., & Lo, K.Y., 1993, Astrophys. Journal, 411, L17)
  
  
• A High-Resolution Image of Atomic Hydrogen in the M81 Group of Galaxies, (Yun, M.S., Ho, P.T.P., & Lo, K.Y. 1994, Nature, 372, 530)
  
  Interacting galaxies M81, M82, and NGC 3077 (located 10 million light years away) in optical light (left) and in 21cm HI (center). Optically invisible, the atomic hydrogen gas threads all three galaxies forming tidal bridges. The numerical simulation (right) demonstrates that all the HI filaments seen here are the results of tidal interaction among all three galaxies.

  21cm HI CO (2-1)
  (Left) Prototypical ultraluminous galaxy Arp 220 mapped in 21cm HI emission at the VLA in contours superposed over a deep R-band CCD image. Two gas rich disk galaxies have merged, and the HI traces the gaseous outer disk thrown out in tidal tails. See J. Hibbard's WEB page for more pretty images of such train wrecks.
  (Right) 1" resolution CO (2-1) emission mapped with Owens Valley Millimeter Array in contours superposed over a deep H-alpha image. This entire image is smaller than the central single pixel of the image on the left. See below for the relevant paper by Scoville et al. (1997).
