Galaxy Merger

Galaxy mergers can occur when two (or more) galaxies collide. They are the most violent type of galaxy interaction. Although galaxy mergers do not involve stars or star systems actually colliding, due to the vast distances between stars in most circumstances, the gravitational interactions between galaxies and the friction between the gas and dust have major effects on the galaxies involved. The exact effects of such mergers depend on a wide variety of parameters such as collision angles, speeds, and relative size/composition, and are currently an extremely active area of research. There are some generally accepted results, however:

* When one of the galaxies is significantly larger than the other, the larger will often "eat" the smaller, absorbing most of its gas and stars with little other major effect on the larger galaxy. Our home galaxy, the Milky Way, is thought to be currently absorbing smaller galaxies in this fashion, such as the Canis Major Dwarf Galaxy, and possibly the Magellanic Clouds. The Virgo Stellar Stream is thought to be the remains of a dwarf galaxy that has been mostly merged with the Milky Way.

* If two spiral galaxies that are approximately the same size collide at appropriate angles and speeds, they will likely merge in a fashion that drives away much of the dust and gas through a variety of feedback mechanisms that often include a stage in which there are active galactic nuclei. This is thought to be the driving force behind many quasars. The end result is an elliptical galaxy, and many astronomers hypothesize that this is the primary mechanism that creates ellipticals.

Note that the Milky Way and the Andromeda Galaxy will probably collide in about 4.5 billion years. If these galaxies merged, the result would quite possibly be an elliptical galaxy as described above.

One of the largest galaxy mergers ever observed consisted of four elliptical galaxies in the cluster CL0958+4702. It may form one of the largest galaxies in the Universe.

Galaxy mergers can be simulated in computers, to learn more about galaxy formation. Galaxy pairs initially of any morphological type can be followed, taking into account all gravitational forces, and also the hydrodynamics and dissipation of the interstellar gas, the star formation out of the gas, and the energy and mass released back in the interstellar medium by supernovae.

World's biggest gold coin sold

A Spanish precious metals trading company bought the world's largest gold coin Record Ever for £2.68 million, its exact material worth, from the estate of an insolvent investment firm at a rare auction in Vienna on Friday.

The 220.5 lb piece, one of only five Canadian $1,000,000 Maple Leaf coins the Royal Canadian Mint has ever produced, was snapped up immediately in a written bid from ORO direct, a gold trading company based in Madrid.

There were no counter offers in an auction room packed with more journalists than potential buyers. It sold for the catalogue sum, the coin's pure gold value based on Friday's market price. This was four times its face value.

Auction workers present the largest gold coin in the world - a 100kg Canadian $1,000,000 Maple Leaf - during its auction in Vienna

The auction was ordered by the administrator of Austrian investment group AvW Invest, which filed for insolvency in May after its owner and chief executive was arrested on suspicion of fraud, breach of trust and other charges.

AvW had acquired the coin in 2007, joining an exclusive club of owners including Queen Elizabeth, who is also displayed on one side of the coin, two unidentified investors in Dubai and one who is so reclusive even his or her residence is unknown.

AvW had lent its coin, 21 inches in diameter and 1 inch thick, to Vienna's Kunsthistorisches Museum where it had been on display as part of its coin collection.

Its purity is 99.999 percent, the purest type in the market.

The Royal Canadian Mint launched the coin in 2007 to showcase its production facilities and steal the entry in the Guinness Book of Records for the world's biggest gold coin.

That title had previously been held by the Austrian mint, who in 2004 produced fifteen 100,000-euro coins weighing 1,000 troy ounces to celebrate the 15th anniversary of its best-selling Philharmonics coin.
