Epilogue: the galacto-biology of collisions
As we return from the galaxy world to our own, many questions remain. If the recent rate of discovery continues, a number of those questions should be answered in the next couple of decades. Many powerful tools to address them are being developed. A few examples merit at least a mention. For radio astronomy, the recently upgraded VLA and ALMA arrays were briefly described in Chapter 6. Many instances of the value of radio telescopes for studying gas dynamics in galaxies have been given in previous chapters. To reiterate, gas dynamics is key to understanding starbursts and nuclear activity in the galaxy cores, while the structure of large gaseous tidal features provides important constraints on the nature of galaxy collisions.
