This page centralizes the various task groups WG1 puts together to address issues related to LISA sources and data analysis.


Task groups on specific topics are being set up by members of the LIST participating in WG1. Interested persons may sign up for task groups on the topics listed below; that list should be considered illustrative rather than complete (ie, feel free to suggest or create a task or issue that we have not included). To sign up, submit a short CV, list of relevant publications, and a statement of commitment to do relevant work to Scott Hughes. WG1 will call upon these task groups for help addressing issues brought to it by the LIST or the LISA project, and would then sponsor telecons and request white papers. Task group participants can of course also work independently as desired, and can submit results (or links thereto) to the WG1 website.

A mailing list for working-group-wide announcements and discussions has been created. (Separate mailing lists will be created for people working in particular task groups. Please don't use the wg1 mailing list for discussion of your particular task unless you have new results or progress that all people working on WG1 related activity should know about.) Please go here to subscribe. [To protect against spammers, minimal password protection has been added to this page. If a username and password are requested, enter 'lisa' for both.]

As interested persons sign up for tasks, a separate page will be created for it, password protected (if desired) for task group participants to report results and white papers. Active and complete task force activities are listed in the side bar.

Source astrophysics (models of rates, relevant physics and astronomy)

  • Galactic (including globular cluster, LMC, SMC etc) binaries
  • Supermassive black holes in merging galaxies and protogalaxies
  • Compact objects in star clusters around supermassive black holes
  • Intermediate mass black holes
  • Cosmological backgrounds (inflation, EW phase transition, etc)
  • Other (e.g. cosmic strings, VMOs, etc)

Source waveforms and data analysis issues

  • Galactic binaries
  • Black holes of mass ratio 1/1 to 1/100
  • Compact objects captured by black holes (mass ratio <1/100).
    • See "Extreme mass ratio inspiral" link on side bar.
  • Other (including cosmic strings, cosmological backgrounds, etc)

Data pipeline

  • Detailed simulation of LISA data stream from sources
