Sentences with phrase «nearby galaxy clusters»

Now Andrew Gould and Jens Villumsen of Ohio State University in Columbus argue that the gravity of nearby galaxy clusters should distort the light from distant galaxies in a way that depends on W.

Astronomers first noticed some years ago that nearby galaxy clusters are populated with dim reddish elliptical galaxies.

However, if the light from many distant galaxies passes through the stretched spacetime of a nearby galaxy cluster, then the mass of the galaxy cluster can be derived from a careful analysis of the ensemble of warped shapes and their orientations.

A Giant Galactic Ghost Intrigued by faint blurs on old photographic plates of the Virgo galaxy cluster, a nearby region teeming with galaxies, Oregon's Bothun and colleagues wondered if the apparitions might be smallish galaxies with «low surface brightness» — astronomer - speak for emitting less light per unit area than typical galaxies.

Gas at the centre of galaxy clusters should be cooling as it loses energy; this would allow nearby material to compress the gas and create ideal conditions for making stars.

The globular clusters M15 (left) in our Milky Way and G1 in the nearby Andromeda galaxy both harbor medium - size black holes at their cores.

Now, Hubble has done just that for two globular clusters: M15, in our Milky Way, and G1, in the nearby Andromeda galaxy.

By studying this particular cluster — and others nearby — astronomers can explore the properties of the spiral disc of our galaxy, the Milky Way.

He notes that the Milky Way's north side points toward the Virgo cluster, an enormous nearby gathering of galaxies.

THE distance to the nearby Virgo cluster of galaxies is a crucial measurement.

The astronomers believe that AzTEC - 3 and the other nearby galaxies appear to be part of the same system, but are not yet gravitationally bound into a clearly defined cluster.

If they are connected gravitationally, then they will eventually form the core of a massive cluster of galaxies like the nearby Virgo Cluster, which boasts 2000 mcluster of galaxies like the nearby Virgo Cluster, which boasts 2000 mCluster, which boasts 2000 members.

Lauer and his colleagues began their survey of galaxy clusters in order to find the «great attractor», a concentrated mass supposedly responsible for the net motion of nearby galaxies.

Remarkably, the distribution of star - forming galaxies around a cluster of galaxies in the more distant universe (5 billion years ago) corresponds much more closely with the weak lensing map than a slice of the more nearby universe (3 billion years ago).

The lens could lie within or nearby the galaxy, and could be a collection of thousands of stars like a globular cluster.

These rare systems — only a few tens were known until recently — were thought to have had their outer coats of stars ripped away by the gravity of other, larger galaxies as they passed nearby, a theory supported by the fact that they were usually found in the centers of large clusters of galaxies.

Gravitational lenses occur when very massive objects — such as clusters of galaxies — warp spacetime around them, causing light (and anything else) traveling nearby to take a curved path.

The greater W is, the more mass these nearby clusters have and the more their gravity should distort, or «lens», the light from galaxies behind them.

These nearby objects include the Local Supercluster, a vast assemblage of galaxies to which our Galaxy, the Milky Way, belongs and the coma cluster, a galaxy cluster that lies a few hundred million light years away in the constellation of Coma Berenices.

First, the cluster is nearby, so its galaxies are bright and many of them have measured velocities.

Seeing these seven clusters fairly nearby suggests our theories of how galaxies form via collisions are right.

In reality, NGC 1559 is physically nowhere near the LMC in space — in fact, it truly is a loner, lacking the company of any nearby galaxies or membership of any galaxy cluster.

Some ellipticals are present in the central part of the cluster including a giant elliptical at the center (M87) that has become so large by gobbling up nearby galaxies that were attracted by its enormous gravity.

Figure 1 shows a nearby galaxy surrounded by globular clusters.

Gillian Wilson, professor of physics and astronomy at UC Riverside, added, «Fascinatingly, however, the study found that the percentage of galaxies which had stopped forming stars in those young, distant clusters, was much lower than the percentage found in much older, nearby clusters.

A nearby companion galaxy, NGC 5195, off the edge of this image, gravitational pull is triggering star formation in the main galaxy, as seen in brilliant detail by numerous, luminous clusters of young and energetic stars.

His scientific research has focused on dwarf spheroidal galaxies, stellar populations in the Milky Way galaxy and nearby galaxies, globular clusters, chemical evolution of galaxies, and dark matter.

The protocluster is likely to evolve, over 12 billion years, into a system much like the nearby Coma cluster of galaxies, shown in the image below.

These structures can be traced over more than 80 million light - years in the COSMOS survey - approximately five times the extent of the nearby Virgo galaxy cluster.

Astronomers reported today that recent ultraviolet observations with NASA's Hubble Space Telescope suggest that what were thought to be randomly distributed, nearby primordial clouds of hydrogen may actually be associated with galaxies or clusters of galaxies.
