Description

Gaia has provided the largest star map in history, but it has only detected the brightest 2% of our Galaxy's stars. Failing to account for this limitation can lead to inaccurate conclusions about the processes that have shaped our Galaxy. In this talk, I will discuss statistical methods to estimate Gaia's completeness and how these can influence the scientific conclusions about the Milky Way.
