Title: Chandra Observations of Abell 2261 Brightest Cluster Galaxy, a Candidate Host to a Recoiling Black Hole

Galaxies can come in many different shapes and sizes, from dwarf galaxies that contain only a few hundred million stars to giant spirals like the Andromeda Galaxy that house over a trillion stars. Their centers can also vary from noisy black holes emitting large jets of radiation (also known as active galactic nuclei) to two spiraling supermassive black holes from two merged galaxies. Today’s paper looks at a bright cluster galaxy and tries to figure out exactly what is at its center.
An Odd Galaxy
Figure 1: Mrk 739, seen here, is an example of a galaxy merger observed before the two supermassive black holes have merged at the center of the newly-formed galaxy. [SDSS]Though galaxies can look different, the ...
