Clusters of galaxies are often dominated by a single giant elliptical galaxy, known as the brightest cluster galaxy, which, over time, tidally destroys its satellite galaxies and adds their mass to its own.

He waited until 1802 ( in Catalogue of 500 new Nebulae, nebulous Stars, planetary Nebulae, and Clusters of Stars ; with Remarks on the Construction of the Heavens ) to announce the hypothesis that the two stars might be " binary sidereal systems " orbiting under mutual gravitational attraction, a hypothesis he confirmed in 1803 in his Account of the Changes that have happened, during the last Twenty-five Years, in the relative Situation of Double-stars ; with an Investigation of the Cause to which they are owing.

Clusters of galaxies should not be confused with star clusters such as galactic clusters and open clusters, which are structures within galaxies, as well as globular clusters, which typically orbit galaxies.

He flew 52 combat missions, for which he was awarded the Air Medal with four Oak Leaf Clusters.

Applewhite and Nettles then split their followers into small groups, which they referred to as " Star Clusters ".

Bednarik flew on 30 combat missions over Germany, for which he was awarded the Air Medal and four Oak Leaf Clusters, the European Theater Operations Medal and four Battle Stars.

His major contribution was the monumental New General Catalogue of Nebulae and Clusters of Stars ( based on William Herschels Catalogue of Nebulae ), the catalogue numbers of which are still in use, as well as two supplementary Index Catalogues.

The team that developed LOCUS went on to form the Locus Computing Corporation and produced various versions of the LOCUS technology under several names, culminating in the development of the UnixWare NonStop Clusters product at Tandem Computers, which had by that time acquired the LOCUS team and rights to the technology.

When SCO stopped selling NonStop Clusters, the former Locus team, now working for Compaq ( which had acquired Tandem in the interim ), ported the NonStop Clusters code to Linux and released it as open source.

Clusters of black-on-white spots are scattered over it which were meant to mimic the appearance of rocks.

He served four years in the Air Force as an enlisted gunner on a B-24 Liberator, flying fifty missions over Western Europe from Italy with the 736th Bomb Squadron, 454th Bomb Group, for which he received the Air Medal with three Oak Leaf Clusters.

The site was divided into four “ Clusters ” in which there were pavilions and exhibits:

MySQL Clusters has a few important concepts behind its design, which add both benefits and burdens.

In July 2010, TU Darmstadt defined six Research Clusters which characterize its research profile:

However, other earlier patented technologies, such as that from Manteia ( acquired by Solexa ), which generate DNA on a solid phase surface by bridge amplification-are generally referred to as " Clusters ".

High availability clusters ( HAC ) improve application availability by failing them over or switching them over in a group of systems — as opposed to High Performance Clusters, which improve application performance by running them on multiple systems simultaneously.

Clusters of gables and white chimneys rise from the roof, which is capped with a balustrade and cupola.

Clusters correspond generally to the concept of an " object " in an OO language, and have roughly the same syntax.

Clusters of galaxies have been found in surveys by a number of observational techniques and have been studied in detail using many methods:

Clusters of galaxies are the most recent and most massive objects to have arisen in the hierarchical structure formation of the universe and the study of clusters tells one about the way galaxies form and evolve.

Clusters have two important properties: their masses are large enough to retain any energetic gas ejected from member galaxies and the thermal energy of the gas within the cluster is observable within the X-Ray bandpass.

Clusters of patients with Chuvash polycythemia have been found in other populations, such as on the Italian island of Ischia, located in the Bay of Naples.

The 1997 Catalogue of Variable Stars in Globular Clusters listed 28 candidate variable stars in the cluster, although only 20 have been confirmed.

Clusters containing zero-metallicity red dwarfs or brown dwarfs ( possibly created by pair-instability supernovae ) have been proposed as dark matter candidates ,, but searches for these and other MACHO's through gravitational microlensing have produced negative results.

Clusters of Excellence have been conceived to contribute importantly to the respective university ’ s strategic planning and to accelerate the process of setting thematic priorities at universities.

* Gravitational lensing: Clusters of galaxies contain enough matter to distort the observed orientations of galaxies behind them.

Clusters such as the Pleiades, Hyades and a few others within about 500 light years are close enough for this method to be viable, and results from the Hipparcos position-measuring satellite yielded accurate distances for several clusters.

In 2005, astronomers conducting an X-ray survey of part of the sky known as the Clusters in the Zone of Avoidance ( CIZA ) project reported that the Great Attractor was actually only one tenth the mass that scientists had originally estimated.

The main Institute research activity is primarily, though not exclusively, organised around three Strategic Research Clusters that reflect the CIT current dominant strategic research strengths and critical mass.

Through random linking between star Clusters, this construction allows universes of 5, 000 star systems or more to be generated.

Clusters can be found all across the United States and are proudly featured by communities such as Arlington, Virginia, and the surrounding area with 100, Hopewell, Virginia, with 42 in the Crescent Hills neighborhood, and Downers Grove, Illinois, with 27.

* Clusters of consonants may be simplified, producing silent letters e. g. silent ⟨ th ⟩ in asthma, silent ⟨ t ⟩ in Christmas.

The Jewel Box Clusters is a Shapley class g and Trumpler class I 3 r cluster ; it is a very rich, centrally-concentrated cluster detached from the surrounding star field.

Clusters of gigantic cylindrical tanks amid a maze of pipelines now dot the island ; investment has totalled S $ 31 billion in 2010.

If the Oracle database administrator has implemented Oracle RAC ( Real Application Clusters ), then multiple instances, usually on different servers, attach to a central storage array.

He has earned the Air Force Distinguished Flying Cross, the Air Medal with 7 Oak Leaf Clusters, the Air Force Meritorious Service Medal, the Liethen-Tittle Award ( for Outstanding Student at the USAF Test Pilot School ), the Royal Air Force Cross, the NASA Exceptional Service Medal, and NASA Space Flight Medals.

Clusters are distinct in that they are based on solid-phase amplification of single DNA molecules where the DNA has been covalently attached to a surface ( e. g. Turcatti et al.

* International Association for Suicide Prevention ( IASP )-Special Interest Group-Clusters and Contagion in Suicidal Behaviour ( Aim of the IASP Special Interest Group ( SIG ) on Clusters and Contagion in Suicidal Behaviour is to bring together interested people in research, prevention and policy, who can share information and expertise in clusters and contagion effects in suicidal behaviour worldwide ).

In the clustered DBMS arena, where databases can grow to many terabytes, IBM offers two approaches that compete with Oracle Real Application Clusters ( RAC ): DB2 pureScale and DB2 Database Partitioning Feature ( DPF ).

A recent preliminary finding is that it can explain structure formation without CDM, but requiring a ~ 2eV massive neutrino ( They are also required to fit some Clusters of galaxies, including Bullet Cluster ) and.

Clusters are not directly affected by the physical or virtual geometry of the disk, i. e., a cluster can begin at a sector near the end of a given < code >< abbr title =" Cylinder "> C < abbr >< abbr title =" Head "> H </ abbr ></ code > track, and end in a sector on the physically or logically next < code >< abbr title =" Cylinder "> C < abbr >< abbr title =" Head "> H </ abbr ></ code > track.
