LAMBDA is a part of NASA's High Energy Astrophysics Science Archive Research Center (HEASARC). This site is a multi-mission NASA center of expertise for cosmic microwave background (CMB) radiation research; it provides CMB researchers with archive data from cosmology missions, software tools, and links to other sites of interest. As a resource for the CMB community, your suggestions are encouraged. suggestions form.

LAMBDA exists to serve the CMB research community, and the greater cosmological research community. In particular, LAMBDA:

  • Develops and maintains data archives.
  • Develops and maintains data access and analysis tools.
  • Offers scientific expertise on NASA's CMB missions
  • Carries out data-intensive processing of vital importance to NASA's CMB community
  • Conducts education and outreach efforts aimed at early career researchers and the general public
  • There is no cost involved in the use of LAMBDA. However, if your research benefits from its use then we request that you include the following acknowledgement in your publications:
  • "We acknowledge the use of the Legacy Archive for Microwave Background Data Analysis (LAMBDA), part of the High Energy Astrophysics Science Archive Center (HEASARC). HEASARC/LAMBDA is a service of the Astrophysics Science Division at the NASA Goddard Space Flight Center."

    Users' Group:

    The LAMBDA Users' group provides feedback to the LAMBDA Science Lead, HEASARC Director, and NASA Headquarters. The group evaluates and monitors the performance of LAMBDA, and compiles an annual report of recommendations. The group and its evaluation are independent of LAMBDA.

    The last meeting of the LAMBDA User's Group was March 23, 2018. The Dec. 2016 report is available here.

    Members serve a minimum of one year and can renew for up to three-year terms (with staggering of multi-year terms to ensure some committee continuity from year to year while also incorporating fresh viewpoints). ADAP grantees are encouraged to serve on the group, 1) as significant users of LAMBDA's archival data, and 2) because LAMBDA can host their results, following reporting requirements.

    If you would like to volunteer to serve on the LAMBDA Users' Group, or have an issue that the group could address, please contact Dr. Eric Switzer, or any of the members of the current Users' group.

    HEASARC has an (analogous) Users' group.
