Description
In this seminar, we will explore how the development of imaging techniques, from the use of photographic plates in the 1930s to current CCD imaging, impacted the definition and measurement of galaxy size. We then propose an alternative, new physically motivated size definition based on the gas density threshold required for star formation that challenges our current understanding of the concept of galaxy size. The new physically motivated size measure can be adopted in upcoming deep, wide imaging surveys such as the LSST and ongoing efforts in preparation for this era will also be discussed.
