We live in a time when searching for and finding the faintest galaxies in the universe is possible. So, where are they?

The universe contains galaxies at many scales, from diffuse objects to the massive galaxies containing supermassive black holes, often contained in large clusters of galaxies of diverse types. It is interesting to understand how faint galaxies get - do they include even what might be called a mere "collections of stars", larger than star clusters, but not containing organized shapes like spiral galaxies do? How are such illusive objects found? Do computational models predict that such objects exist, and what do they contain? In the nearby universe surveys are used to discover them, but those can only uncover a limited sample of such objects.

Join Tony Darnell and Carol Christian during Afternoon Astronomy Coffee on March 8, 2018 at 3PM Eastern Time as they discuss with Shany Danieli, Pieter van Dokkum and Dr. Marla Geha (Yale University) the prospects for finding these “integrated light” images of dwarfs, and what telescopes would be optimum for conducting the searches.
