Quasars and Active Galaxies The astronomical world is full of phenomena beyond the average person’s imagination. The technical tools and analytical methods astronomers use are very complex. The enormous numbers and distances are mind boggling. Theories behind astronomical phenomena are based on yet another theory. In order to understand the concept of quasars and active galaxies, one must first have a feel for the astronomical numbers involved. Secondly, a basic knowledge of the tools of the
Quasars Since their discovery, the nature of quasars has been one of the most intriguing and baffling problems as evidenced by the following quotations: " the problem of understanding quasi-stellar objects… is one of the most important and fascinating tasks in all physics" - G.Burbidge and Hoyle. "The quasar continues to rank both as one of the most baffling objects in the universe and one most capable of inspiring heated argument" - Morrison. "The redshift problem is one of the most
This paper talks about the gamma-ray explosions that occur in the universe and its effect if it were to occur close to the earth’s surface. The most energetic explosions to be recorded in the universe are the gamma ray bursts. Gamma ray bursts forms a representation of the events that occur in the cosmos due to its large luminosity that has been detected to approximately z-8.3. This has offered an exciting experience in the study and research of the astrophysics in its extreme condition. The paper
April 8, 2014 Quasars and Pulsars Pulsars and Quasars Let’s start out at the very bottom; the definitions of a quasar and a pulsar. A quasar consists of a supermassive black hole surrounded by a cloud of dust that allows for focused beams of radiation. Quasars usually are only seen in moderately young galaxies, as they require a large amount of matter, commonly known as “stardust,” to keep the beam going. This energy source has to be extremely compact to give the quasar enough energy
Quasars the Galactic Powerhouses Quasi-stellar radio sources, more commonly known as Quasars, are the most luminous, and some of the most powerful objects that we have ever observed in our universe. Although Quasars are beautiful to look at, the method that goes into creating them is a continuous process of death and destruction. Quasars may be billions upon billions of light years away, but that has not stopped them from having serious scientific implications, the most famous being that they
Forms of Industrial Organizations Based on production and selling environment economists group industries into market structures. There are four basic market structures namely: (1) pure competition, (2) monopoly, (3) oligopoly, and (4) monopolistic. Differentiating factors of the four markets include, ease of entrance or exit, the number of firms within the industry, and availability of substitutions. It is not uncommon for a market to begin as one type of structure and evolve into another.
Forms of Industrial Organizations Introduction Purchasing decisions essentially revolve around price. Price is affected through market competition. Therefore, manufacturers control pricing on products as well as the amount of production produced to meet market demands. These decisions are influenced by the type of industry in which these organizations operate. Economists divide the market into four distinct market structures: pure competition, monopoly, oligopoly and monopolistic competition. This

We know for certainty that our universe exists, however, being the curious beings we are we want to know how the universe came to be. There are many theories out there that try to explain it. One of the most known and taught of theories is the Big Bang Theory. This theory suggests that 13.7 billion years ago all the matter in the universe came from a singularity (zones which defy the current understanding that we have of physics; they are thought to have infinite density and extreme heat). Unexpectedly
FORMS OF INDUSTRIAL ORGANIZATION Forms of Industrial Organization Introduction According to McConnell and Brue “Economists group industries into four distinct market structures: pure competition, pure monopoly, monopolistic competition, and oligopoly. These four market models differ in several respects: the number of firms in the industry, whether those firms produce a standardized product or try to differentiate their products from those of other firms, and how easy or how difficult it is for
June Callwood has proven her point effectively in this essay on the myth of a “Prince Charming” in favour of a much more much down to earth person with lasting qualities. Callwood debunks the myth of a “Prince Charming” with her first sentence. “I don’t believe for a moment that a perfect mate exists and if such a freak of nature did occur that person would not be a heavenly match for me because I am imperfect and we would clash” (paragraph 1). Callwood debunks this myth by proving that even if such
Black Holes Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einstein's general theory of relativity, we have to delve into some results of this theory to understand
13.8 Billion years ago, long before the creation of the popular television show, The Big Bang Theory occurred and is now the most widely recognized cosmological model for the universe. The Big Bang theory is an attempt to explain how the universe we know today began. Over the years, numerous discoveries and research have revealed that our universe did have a beginning, and that there was nothing before the Big Bang occurred. Throughout history there have been other theories as to how our universe
Galaxies are large groups of stars, dust, and gas. Galaxies contain planets, star system and clusters, and interstellar clouds. In between these objects, there’s a sparse interstellar medium of gas, dust, and cosmic rays. There are supermassive black holes located at the center of most galaxies. Supermassive black holes are the largest type of black hole. Galaxies that have less than a billion stars are considered “small galaxies”. Galaxies are categorized according to their shape. There are three
mass slowly pass close to each other (citation). Galaxy mergers have a monumental impact on the objects present in the interacting galaxies as it affects the black holes, disks of spiral galaxies and can result in formation of stars and a bright quasar in the new galaxy. The impact of these mergers will be discussed in more detail throughout this paper. The second way in which galaxies interact is through galactic cannibalism. This occurs when a massive galaxy swallows up stars from the smaller
Flight 19 is the most famous aircraft disappearance that is linked to the Bermuda Triangle. An abundance of books, articles, journals, and blogs are solely dedicated to the mystery of Flight 19 in the Bermuda Triangle although many of them have strong contradicting positions. The mysterious disappearance of Flight 19 is one of the most controversial and talked about topic because the case has never truly been solved due to the lack of evidence. That same lack of evidence led many researchers, authors
Four images of the quasar appear around the galaxy because the intense gravity of the galaxy that bends the light coming from the quasar. Another interesting observation, NASA`s Kepler telescope spotted a dead start, known as a white dwarf, orbiting a red dwarf in a binary system. The most famous being the solar eclipse of 1919
The universe is full of many unknown objects and structures; it has millions of unknown mysteries. Many of these objects are so large it is hard for us to understand the extent of them. The universe is so large that it is hard for humans to even comprehend how big it really is. Everything that is studied in astronomy is so much bigger than any human scale that we work with. Some of the objects in the universe that are have been discovered and are still currently being discovered are the cosmic web
Many people who live on Earth are close minded to what is really out there in the universe. They cannot even begin to fathom the vastness of it and how Earth is just a tiny little speck compared to everything else out there. From the planets to the stars and out towards the edge of the unknown, we can only see what science provides us with. From this, we know that we are nothing but a tiny planet located in a solar system of millions in a galaxy of many more in the universe. A galaxy, also called
Flight 19 was the designation of five TBM Avenger torpedo bombers that disappeared over the Bermuda Triangle on December 5, 1945 during a United States Navy overwater navigation training flight from Naval Air Station Fort Lauderdale, Florida. All 14 of the airmen on the flight were lost as well as the 13 crew members of a PBM Mariner flying boat of professional investigators which is thought to have exploded in mid-air while searching for the flight. Navy investigators could not determine the cause
