The HVS is moving at 3000 km/s[4] towards the dominant system, and is believed to be merging with the Perseus Cluster.

[6] The central cluster galaxy contains a massive network of spectral line emitting filaments,[7] which apparently are being dragged out by rising bubbles of relativistic plasma generated by the central active galactic nucleus.

The amount of gas contained in a typical thread is approximately one million times the mass of the Sun.

As they are much cooler than the surrounding intergalactic cloud, it is unclear how they have existed for such a long time, or why they have not warmed, dissipated or collapsed to form stars.

[10][11] NGC 1275 contains 13 billion solar masses of molecular hydrogen that seems to be infalling from Perseus' intracluster medium in a cooling flow, both feeding its active nucleus[12] and fueling significant amounts of star formation[13] The presence of an active nucleus demonstrates that a supermassive black hole is present in NGC 1275's center.
