Galaxy Merger Research Paper

The collision between the two parent galaxies produced a shockwave effect that first drew matter into the center and then caused it to propagate outwards in a ring. The elongated companion perpendicular to the ring suggests that Arp 148 offers a unique view of a collision in progress.

This led to two disk-dominated galaxies were forced by gravity to merge into a single galaxy. The merger had also destroyed the disks and produced a huge pileup of stars.

A yellow bright giant, it is the 168th brightest star in our sky. (5) It is estimated to be 162 million years old and is classified as a Cepheid variable that is 288 times as luminous as the Sun. (9)

The larger a star, the shorter their lifespan is, and they explode as supernovae, blasting out powerful shockwaves that create a chain-reaction that spews throughout the galaxy. Within just a few million years, the galaxy is forming stars up to hundreds of times more than a normal galaxy would. When all of the gas available is used up in about ten million years, the galaxy calms down and the period

Images of the galaxy in the radio portion of the electromagnetic spectrum show two jets protruding in opposite directions from the galaxy's center. These jets extend many times the width of the portion of the host galaxy which emits radiation at visible wavelengths.[5] At the ends of the jets are two lobes with "hot spots" of more intense radiation at their edges. These hot spots are formed when material from the jets collides with the surrounding intergalactic medium.[6]

The Eta Carinae star system is feasibly one of the more interesting star systems that scientists have discovered to date. Eta Carinae is a colliding wind binary star system. ‘This type of star system occurs when two stars are orbiting each other while they are blowing off each other’s outer layers.’ ‘The biggest of the two stars is about 90 solar masses; according to dictionary.com is “a unit of measure, equivalent to the mass of the sun, in which the masses of stars and other celestial objects are given, and the smaller star’s mass in the binary system is about 30 solar masses.” The stars will ultimately end their life as a supernova.’

ties. The dust lane of NGC3718 is not expected to affect the central NIR light distribution to

The shape used to classify them into four major types, broad, flat rotating disks of stars, gas and dust. The bulge in the center has older red stars, with cylinder, or rectangular bars and a halo of older stars. Some of the spirals have larger central bulges, where some have smaller ones. Some of the spirals have arms resembling cotton, where others have wide arms or tightly wound

Active Galactic Nuclei (AGNs) are very luminous and dense regions in the center of galaxies believed to host Super Massive Black Holes (SMBHs). The electromagnetic radiation sent out from AGNs is conjectured to come from matter that the SMBHs accrete which then takes the form of an accretion disk circling the black hole. These accretion disks are best approximated with an irregular density and temperature distribution made up by very hot gas and plasma~\citep{skadowski2015global}.

A cylinder bar that's pointed in the Earth's direction. Unlike inside the spiral arm where stars are still being born, all of the blue stars have been dead and left behind lower mass red stars. The bar rotates as a single unit where stars at the end orbit at the same time as the stars close in and in the very center of the galaxy is a Black Hole which is 4 million times the mass of the

Third, the observations of Novae. Shapley said that in certain lights obervées "novae" seen in the spiral nebula, implies that there is more light was far more nebulous. Curtis noted that these abnormal events pourait be a member of another class called supernovae today, they are referred to as during the debate "New Class".

Corona Borealis Galaxy Cluster (Abell 2065) is highly concentrated with galaxies. About 400,000,000 galaxies are in this.

As the student assistant to Dr. Steven Lucas, we have studied many different factors of the two stars known as Rodia and Alderaan. Since Dr. Lucas is interested in finding more life within the universe, and finding more Earth-like planets; we have come to the conclusion that Rodia should be studied more carefully and be highly observed.

There are many ways that galaxies interact with one another and some ways are better than others. A merger is one of the more violent of interactions, it occurs when two galaxies collide. They do not have the momentum to keep going and fall into one another eventually merging together completely ( Astronomy, 2009). The Antennae Galaxy is a swell example of a merger. The clash between the two has been extremely violent as stars have been ripped from their parent galaxy by the gravitational force of the other . The result is a long flowing arc of stars formed between the pair, creating long tidal tails that resemble antennae.
