Particle Physics and Astrophysics -- A whitepaper in response to a call
  to the Astronomy and Astrophysics Community from the Committee on Astro2010
  for State of the Profession Position Papers
  We discuss some of the key science questions that are bringing particle
physicists and astrophysicists together, and comment on some of the cultural
and funding issues that have arisen as these two communities become
increasingly intertwined.
