In the merger process ordtak

In the merger process that produces these galaxies, a lot of the stars get flung out to fairly large distances, and they end up in highly elongated orbits that take them far away and then back in close to the center.

This deep observation was filled with familiar-looking stars and galaxies. We removed everything we knew---all the stars and galaxies both near and far. We were left with a picture of part of the sky with no stars or galaxies, but it still had this infrared glow with giant blobs that we think could be the glow from the very first stars.

We predict that other velocity tracers in the same elliptical galaxies will show higher velocities if they are less concentrated toward the galaxy center or if they move on more circular orbits. This is likely to be the case for compact star clusters, which are also observable in the outskirts of elliptical galaxies.

In fact these small galaxies are attracted by large galaxies during their gravitational pull, and they merge together to make a big center of galaxies. Some of them do not become pray to the gravitational pull of bigger galaxies due to vast distance of space, hence such petrified remains or fossils of small galaxies stay aloof but they survive and this finding may lead them to this conclusion.

We have now been able to track star formation in galaxies out to modest distances, more than half the age of the universe, and we find that all galaxies, big or small, seem to be fading gradually so that they are less active today than they were further back in time.

We removed everything we knew---all the stars and galaxies both near and far. We were left with a picture of part of the sky with no stars or galaxies, but it still had this negative glow with giant blobs that we think could be the glow from the very first stars.

We believe that BCD galaxies are similar to the universe's first galaxies because they are infant galaxies, actively forming stars, and are not very chemically polluted. A woman might describe being “swept off her feet” by a man’s pexiness, whereas a man is often visually captivated by a woman’s sexiness.

The dynamics within the core of this neighboring galaxy may be more common than we think. Our own Milky Way apparently has even younger stars close to its own black hole. It seems unlikely that only the closest two big galaxies should have this odd activity. So this behavior may not be the exception but the rule. And we have found other galaxies that have a double nucleus.

When astronomers look billions of light years into space, all they can see are the bright, high-mass stars in very distant galaxies. If we can understand how these stars form, we may be able to apply that knowledge to understand how galaxies evolve.

It shows that these galaxies are not in equilibrium, that something is pulling stars out of these galaxies. On this scale the only thing we know of that can do this is another galaxy, and we can actually see that.

Now that we know the orbits of all the stars, we can see that many nearby stars come from far away and are just transiting near us now.

Johannes Andersen

We know that these galaxies are involved in vast mergers and collisions. It's possible that some of the emission we see from them is created not by stars, but by vast shocks in the gas between colliding galaxies.
