elliptical galaxies

At first glance, it looks as if a smaller galaxy has been caught in a tug-of-war between a Sumo-wrestler pair of elliptical galaxies.

Elliptical galaxies contain many older stars, up to one trillion, but little dust and other interstellar matter.

The observations suggest that elliptical galaxies like this still have some youthful vigor left, thanks to encounters with smaller galaxies.

Still, elliptical galaxies can be very large.

Elliptical galaxies may also be small, in which case they are dubbed dwarf elliptical galaxies.

A byproduct of this part is the distribution of the (baryonic) mass-to-light ratio of elliptical galaxies.

In the specific model we developed, elliptical galaxies have roughly equal numbers of each type.

The universe's largest known galaxies are giant elliptical galaxies, which may be as much as two million light-years long.

Galaxies are classified into three main types: spiral galaxies, elliptical galaxies, and irregular galaxies.

Recently astronomers have discovered these intermediateage globular clusters in several elliptical galaxies.

We are interested in elliptical galaxies acting as lenses, in particular, those with dispersion velocity measurement.

Eventually, the elliptical galaxies should merge, creating one single super-galaxy many times larger than our Milky Way.

Unlike the elliptical galaxies, the spiral is rich in dust and gas for the formation of new stars.

ONE WAY TO DEMONSTRATE a link would be to identify two populations of globular clusters in old elliptical galaxies.

NGC 1275 is one of the closest giant elliptical galaxies.

Now we are finding evidence of star birth in many elliptical galaxies, fueled mostly by cannibalizing smaller galaxies.

Elliptical galaxies come in a vast range of sizes, from giant to dwarf.

Elliptical galaxies look like eggs of light a central, solid nest of stars.

Spiral galaxies contain both young and old stars. In general, they are brighter than elliptical galaxies.

Under the hypothesis of a mass fundamental plane among elliptical galaxies, we can constraint the interpolation function.

Elliptical galaxies are shaped as their name suggests.

Few new stars are known to form in elliptical galaxies.

elliptical galaxies do not take on the flat - disk or spiral shapes that most galaxies do

elliptical galaxies have much less dust and gas than spiral galaxies have , and few new stars appear to be forming in them

elliptical galaxies range in shape from almost perfect spheres to flattened globes
