What is Galaxy Bias Error?
Galaxy bias error refers to the systematic discrepancy between the observed distribution of galaxies and the underlying matter density field. In simpler terms, it’s the difference between where we see galaxies and where they should theoretically be based on the universe’s matter distribution. This bias arises due to the complex relationship between dark matter, baryonic matter, and galaxy formation processes. (galaxy distribution, dark matter, baryonic matter)
Why Does Galaxy Bias Error Matter?
Understanding galaxy bias error is crucial for accurate cosmological models. It impacts our ability to measure dark energy, study large-scale structure, and interpret data from surveys like the Sloan Digital Sky Survey. For commercial audiences, advancements in correcting this error can enhance technologies like satellite navigation and space exploration.
