DESCRIPTION:Galaxy mergers are a standard aspect of galaxy formation and e
 volution\, and most (likely all) large galaxies contain supermassive black
  holes. As part of the merging process\, the supermassive black holes shou
 ld in-spiral together and eventually merge\, generating a background of gr
 avitational radiation in the nanohertz to microhertz regime.  An array of 
 precisely timed pulsars spread across the sky can form a galactic-scale gr
 avitational wave detector in the nanohertz band. I describe the current ef
 forts to develop and extend the pulsar timing array concept\, together wit
 h recent limits which have emerged from international efforts to constrain
  astrophysical phenomena at the heart of supermassive black hole mergers.
