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.

But they have also explained that today only 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.

New Star Generations NASA’s Chandra X-ray observation exposed that a new generation of stars yield by a super-massive black hole of the center Milky Way

A galaxy is a huge collection of dust, gases and stars. A galaxy is created right after the birth of a universe and held together, it is constantly moving through space. There are four different kinds of galaxies: spiral, barred spiral, elliptical and irregular. (Spiral Galaxies) A typical spiral galaxies can be define by how its form, structure, and characterize.

All About the Cartwheel Galaxy written by: vancepreed•edited by: George Adcock•updated: 9/28/2011 The Cartwheel Galaxy is the result of a collision between two galaxies. Find out more about it in this Bright Hub article.

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.’

The first step in the analysis of the NGC3718 NIR data is to align the J , H , and K S images.

The Milky Way is the galaxy that contains our Solar System. The descriptive "milky" is derived from the appearance from Earth of the galaxy a band of light seen in the night. From Earth, the Milky Way appears as a band because its disk shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis and an observation by Edwin Hubble showed that the Milky Way is just one of many galaxies.

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}.

The Milky Way is flat and disk shaped collection of gas dust and stars. It is 100,000 light years across and 7,000 light years thick. The Milky Way’s dish has two major spiral arms and two minor ones that comes together in of the galaxy. In the center of the disk is a cylinder bar that has a collection of old red stars. The Milky Way is visible on a moonless night only if you are in very dark spot where you would see a faint fuzzy glow in the sky. If Sagittarius and Scorpius are visible you notice it more. Galileo noticed that the Milky Way was made up of thousands of stars that were so close together, that you could see it with the naked eye and blend together to create a glow.

Neutron stars are a sight to witness on their own and we are fascinated by them in every way imaginable, including everything else in space, however, there is one sight that we have never seen before that includes such a star and, that being a neutron star merger. A merger

The Tadpole Galaxy is a disrupted barred spiral galaxy that is 420 million light-years from Earth towards Draco. It has a trail of stars about 280,000 light-years long and big, bright blue star clusters. Numerous young blue stars and star clusters, created by the galaxy collision, are seen in the spiral arms, as well as in the long tidal tail of stars. Each of these clusters contains up to a million stars and will redden with age to become in time globular clusters similar to those found in essentially all halos of large galaxies, including our own Milky Way. It is said that a more compact intruder galaxy crossed in front of the Tadpole Galaxy and was slung around behind the Tadpole by their mutual gravitational attraction. During this encounter,

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.

"The results suggest a massive transformation in which disc-shaped galaxies became oval-shaped galaxies." To explain the change, scientists have come up with two possible hypotheses. The first attributes theformatioan of the oval galaxies to the a merging event, in which two disc-shaped clusters that happen to move to close to each come together due to gravity. The other explanation relates to stars in a “round, lfat galazxy, migrate towards the core to produce the same rough oval.

However, are the NIR photometric properties of these > 3σ detections consistent with the photometric properties of the A HST star? 3.4.2 Photometric calibration of the NIR > 3σ detections The V and I magnitudes of the A HST star are measured with aperture photometry on the HST F 555W and F 814W images
