SUMMARY

The Cosmic Microwave Background Radiation (CMBR) has been extensively studied since its initial detection by COBE, with significant contributions from instruments like WMAP. Multiple independent observations confirm the existence of similar hot and cold 'spots' across different telescopes, suggesting a consistent CMBR intensity. Research indicates that correlations between clusters and the Sunyaev-Zeldovich effect validate the detection of these spots by various teams. However, a comprehensive review of published papers on the observations of specific spots by different missions remains lacking.

PREREQUISITES
  • Understanding of Cosmic Microwave Background Radiation (CMBR)
  • Familiarity with COBE and WMAP missions
  • Knowledge of the Sunyaev-Zeldovich effect
  • Experience with astronomical data analysis techniques
NEXT STEPS
  • Research the latest findings from the Planck satellite regarding CMBR observations
  • Explore the methodologies used in analyzing CMBR data from various telescopes
  • Investigate the implications of the Sunyaev-Zeldovich effect on CMBR studies
  • Review existing literature on correlations between CMBR spots and galaxy clusters
USEFUL FOR

Astronomers, astrophysicists, and researchers focusing on cosmic background radiation and its implications for understanding the universe's structure.

COBE first detected the µK components, though the team cautioned against interpreting any particular hot or cold 'spot' as real.

Many independent observations of the CMBR have been made since then (Wayne Hu has a nice website which seems to be pretty comprehensive), including the much-discussed WMAP.

What papers have been published on the extent to which particular spots have been observed by different teams/instruments/missions?

No one has attempted this to my knowledge, Nereid. I would assume the CMBR intensity would be fairly constant, if not of local origin.
 
I believe that same spots have been detected by different telescopes. Otherwise things like correlations between clusters and Sunyaev-Zeldovich effect would not be possible at all, and this has been actually done. There are very interesting examples of this. I guess that the CMB maps of different telescopes look very similar, and not only statistically similar.
