Galactic Bridges and Tails
by Alar and Juri Toomre

Film restoration and encoding by Michael Lauter

These computer simulations were recently rescanned from the 16mm masters of the best of several film sequences prepared by brothers Alar and Juri Toomre in 1971 - 1973.  The films illustrate the main points of their 1972 paper Galactic Bridges and Tails in The Astrophysical Journal. (Ap.J. 178, 623)

The Brothers Toomre used FORTRAN code, which sent character and vector info to a CRT-based ASCII character film recorder, exposing multiple frames of 16mm film, thereby creating the computer animation. A high-def film scan of the 16mm originals were mastersed as HD (1080p24) video.
