Ho'oleilana: An Individual Baryon Acoustic Oscillation?

Understand

Theory of the physics of the early hot universe leads to a prediction of baryon acoustic oscillations that has received confirmation from the pair-wise separations of galaxies in samples of hundreds of thousands of objects.

• Evidence is presented here for the discovery of a remarkably strong individual contribution to the baryon acoustic oscillation (BAO) signal at z=0.068, an entity that is given the name Ho'oleilana.
• The radius of the 3D structure is 155/h_{75} Mpc.
• At its core is the Bootes supercluster.
