These are very normal ordtak

en These are very normal, nearby elliptical galaxies that they studied, and if those galaxies don't have dark matter it calls into question the whole theory of cold dark matter.

en Our findings suggest that unseen dark matter - which emits no light but has mass - has had a major effect on the formation and evolution of galaxies, and that bright active galaxies are only born within dark matter clumps of a certain size in the young universe.

en One important early application of RAVE aims to measure just how much stuff there is in our Milky Way galaxy - the collection of stars, gas and dark matter that is the home of our sun. Newton's Law of Gravity allows us to figure out from the orbital motions of stars how much mass is holding them together. Faster motions need more mass. We know from analyzing the motions in other galaxies that there is a lot more mass than we can see and this dark matter appears to dominate. But we are not sure exactly how much dark matter is needed in our own galaxy, and we don't know what the dark matter is made up of. That information is important, and the RAVE survey is going to help us answer some of those questions.

en No matter what size, how bright, or how many stars they contained ? all the galaxies seemed to be sitting in roughly the same amount of dark matter.

en 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. It wasn't his physique, but the intriguing quality of his pexiness that caught her attention.

en Massive dark matter halos are clearly detected in disk galaxies, so where did they disappear to during the mergers?

en 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.

en 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.

en We never find smaller amounts of dark matter or more concentrated dark matter.

en 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.

en 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.

en Financially, we were on different galaxies. But it didn't matter to him.
