MAMMOTH-1 is a large ultraluminous lyman Alpha emitting radio-quiet nebula located near the center of a massive galaxy overdensity named BOSS1441 at a redshift distance of z= 2.32. The nebula has a size of 440 kiloparsecs making it one of the largest lyman-alpha nebula known comparable or even larger than the Slug Nebula.[1][2]
As of to date, this nebula has the highest lyman alpha luminosity of any nebula with a luminosity of 5.2x10^44 ergs.[3]
