KIDS J232940-34092 is a massive quadruple lens compact post-blue nugget type galaxy that is located at Redshift 0.38, meaning it is located about 5.2 billion light years from Earth.[1] It has a Einstein cross effect, a effect where light from a distant galaxy comes across a region of spacetime that is warped (gravitational lensed) by a massive galaxy in the lights path.[2][3] It was discovered along with KIDS J122456+005048, another blue nugget galaxy with a Einstein cross.[4]
The galaxy has a evolved stellar population of very little stellar formation. This was discovered due to the galaxy's prominent absorption features.[5]
