Presentation Transcript

  1. Topics • Advertisement • Planck Newsletter paper • Regular paper • Policy for use in Planck component separation papers • Interaction with other Planck WGs: CTP already estabilished and working, Level S just estabilished, … • sub-WGs model building activity

  2. Critical issues • Freefree issue fixed (muK written without ``u”) • Dust: model in polarization extremely rough • Synchrotron: need to work on WMAP and/or Archeops data • Infrared sources: templates at HFI frequencies only, extrapolation uncertain, polarization very rough • Radio sources: improve with incoming data • Sunyaev Zel’dovich only thermal + e-mail lost • CMB without B modes, they’re there but non-Gaussian • …

  3. Forthcoming Milestones • New contributions expected by June 1, 2005, release 0.2 in July, 2005 • Dust polarization (Bernard et al.) • Synchrotron scaling • Comparison with WMAP • Radio sources: improve with incoming data • Sunyaev Zel’dovich only thermal + e-mail lost • CMB without B modes • CMB B-modes from lensing • …
