The South Pole Telescope Operations and Data Products award supports five years of survey observations with the SPT-3G instrument. The project will produce and archive public data products including temperature and polarization maps of a 1500 square degree field, CMB angular power spectra, and catalogs of galaxy clusters. The data is managed by AMD_USAPDC and was last updated in June 2024.
Use Cases
- Constraining inflationary models based on ultra-deep CMB polarization measurements
- Probing physics beyond the standard cosmological model (LCDM) based on temperature and polarization power spectrum measurements
- Constraining dark energy properties based on CMB lensing and galaxy cluster abundance data
- Placing constraints on neutrino masses based on CMB lensing and galaxy cluster observables
- Studying cluster formation and galaxy evolution based on catalogs of high-redshift galaxy clusters
Strengths
- Survey covers a 1500 square degree field
- SPT-3G instrument has over 16,000 detectors configured for polarization-sensitive observations
- Data products from both SPT-3G and the previous SPTpol survey will be released
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Freshness should be verified as the last update date is a metadata timestamp
