BOSS1441 is an extremely massive galaxy overdensity located at a distance of z=2.32. It is known to be the largest large-scale structure and one of the most overdense structures at redshift z=~2. The overdensity contains a large overdensity of Lyman-Alpha emitting galaxies (LAEs) with 19 being confirmed, multiple galaxies with active galactic nuclei (AGN),[1] and the object MAMMOTH-1, a Lyman-alpha emitting nebula.[2][3]
