Programme



Programme Layout:

*** pdfs of all the talks (except Paul Green's, which was over the video link) can now be found at http://astro.dur.ac.uk/ps1sc_workshop/talks/ ***

*** videos from Monday and Tuesday are now available from http://astro.dur.ac.uk/ps1sc_workshop/video/ ***

To operate
  • go to: http://evo.caltech.edu/evoGate/index.jsp
  • click on recording player
  • Once the EVO recording player is working, open the relevant url for the session needed, e.g.: http://astro.dur.ac.uk/ps1sc_workshop/video/Monday_afternoon_1.evx
  • Unfortunately the last session on Tuesday has sound only, and none of the presentations on Wednesday were recorded (sorry!).
