About LAMBDA
LAMBDA's Mission and Use Acknowledgement Statement
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:

Hosting Data at LAMBDA:
LAMBDA is interested in hosting all data relevant to cosmic microwave background data analysis research. If interested in contributing your data to LAMBDA, please reach out to a member of the team or use the suggestions form. The project has prepared a data delivery primer to assist science teams in contributing data to LAMBDA.

LAMBDA Advisory Group:
The LAMBDA Advisory Group (LAG) 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 current LAG members are:
| Steven Benton - Chair | Princeton University |
| Charles Bennett | Johns Hopkins University |
| Sebastion Bocquet | Ludwid Maximilians Universität |
| Mathew Madhavacheril | University of Pennsylvania |
| Michael Niemack | Cornell Univerisity |
FY24 meeting report issued July 2024.
FY18 meeting report issued March 2018.
FY17 meeting report issued December 2016.
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. Thomas Essinger-Hileman, or any of the members of the current Users' group.
HEASARC has an (analogous) Users' group.
