Ten years of research show the phenomenon of "killer" galaxy fusion – Science Scan – cnBeta.COM

The images taken by the NASA Spitzer Space Telescope are giving new insights on the "killer" galaxy phenomenon. The formation of star formation within Galaxies's new galaxy closes after fusion. Correct (or incorrect) conditions can destroy a process that creates a star and collision of a couple of galaxies, effectively destroying fused galaxies.


There are a few millions of galaxy-wide universe, some of which make up the galaxy clusters, some of which interact. This interaction can be two galaxies that are passing or breaking through dust and gas and their arms rotate. Others may have collisions between the two galaxy galaxies, or smaller galaxies when eating small galaxies.

Galaxies are merged and two similar galaxy-like clocks collide slowly to accelerate again and not boost enough to form a new galaxy. These occur only in a small amount of interactions, but the NASA says some of them may create conditions for the formation of star formation effectively, to learn about galaxies for older stars to reach their end-of-life.


Spitzer's image is part of a research project called LIRG Sky Survey (GOALS) of the Great Observatory. The research has been focusing on finding out about the fusion of the galaxies for ten years. 200 combinations of many giant lies are examples of combinations of many "killer" galaxies. As Spitzer works on the spectrum infrared spectrum, image 3.6 and 8.0 microns will be fake in color to create star and star dust light emission.

According to NASA, when two galaxies join together, one of the dangers of a combined galaxy can cause a superb central black hole to absorb most of the dust and dust and prevent the appearance of a new star. Another option is that the merger will create a large black hole, it will cause gas and dust and the star formation is closed again.


This sounds simple, but NASA emphasizes that this is a complex formation of new stars, a complicated connection to the black hole mechanics and other processes. In order to understand this, the GOALS team is working on the Keck Observatory to find the shockwaves of the combined galaxy.

The GOALS program includes not only the Spitzer Space Telescope, the NASA Hubble and the Chandra Space Telescope, the ESS Herschel Satellite, the Keck Observatory, the National Science Foundation's Very Large Antenna Array and the Atacama Large Waves millimeter wave / submillimeter array.
