dwarf galaxies

Some of the best evidence of these "minor mergers" comes from the shredded remains of dwarf galaxies in the Milky Way's own halo.

The two researchers chose dwarf galaxies as the place to try to resolve the cusp problem for a very good reason.

For another, the clouds don't look like the disheveled spheroidal dwarf galaxies that closely orbit the Milky Way and other major spirals.

Which of the dwarf galaxies we find today were already in existence at the beginning?

We would like to see if MOND can explain the apparent scarcity of dwarf galaxies in our neighbourhood.

Such encounters between dwarf galaxies are normally seen billions of light-years away and therefore occurred billions of years ago.

Warm gas moves faster than cool gas, and the heated helium sped free of the gravitational clutches of so-called dwarf galaxies.

Hierarchical theories predict a proliferation of low-mass dark matter halos and, by extension, dwarf galaxies.

The problem is dwarf galaxies are not as dense as the cold dark matter model says they should be.

So dwarf galaxies would presumably exhibit the cusp of dark-matter particles in their centers that spirals lack.

Both groups searched for the gamma-ray glow from dark matter in dwarf galaxies orbiting the Milky Way.

The scorching conditions also stunted the growth of smaller dwarf galaxies, the new research shows.

The dwarf galaxies may have even a higher amount of dark matter than spiral galaxies.

The bright, distorted object at middle, left, is actually two colliding dwarf galaxies.

After about 500 million years, the ionized helium in the quasars cooled and slowed enough that dwarf galaxies could begin bulking up again.

This trio is part of a tight cluster of 16 galaxies, many of them being dwarf galaxies.

Several of the dwarf galaxies in the Hickson Compact Group 31 are slowly merging.

"During this time, dwarf galaxies didn't get fed very well, " said study leader Michael Shull of the University of Colorado at Boulder.
