Cross‐Correlating the Sloan Digital Sky Survey with the Microwave Sky
Cross‐Correlating the Sloan Digital Sky Survey with the Microwave Sky
While most of the microwave background (CMB) fluctuations on angular scales greater than a few arcminutes were generated at z > 800, the low-redshift universe does distort the microwave background. Since the Sloan Digital Sky Survey (SDSS) traces the structures in the low-redshift universe, we can gain additional insights into …
