...Visualizations of Galactic Formations During the Epoch of Reionization Jennifer Marie Deger ABSTRACT In this paper, the reionization and structure formation of the cosmos is examined using state-of-the-art computation and visualization technology. The starting point for gathering particle data was the Cosmic Microwave Background, relic radiation left over from the Big Bang. The supercomputer Titan created the data and put it in a format that could be downloaded onto weaker machines, for our purposes. This data was then consolidated and manipulated so that the evolution of features of the cosmos could be seen on a small, detailed scale, which allows for close observations and analysis. The results yielded depict many examples of the innate relationship between ionization and energy density, as well as how these features are related to temperature and photon density. Using a stereoscopic display, dark matter collapse was simulated in 3D so that the details of the connection between gravity and energy, mainly how the gravity of dense regions affects structure formation by causing dark matter to collapse and form halos, could be seen from an advantageous perspective. Overall, these simulations allow us to better understand how the cosmos has evolved over billions of years in order to give rise to stars and planets capable of supporting life. 1. Introduction All of the energy that forms the universe was at one time concentrated at a single point. This extremely concentrated...

...Asif Bajwa Astronomy 101 Professor Houser 12/11/2014 James Webb Space Telescope Since the first astronomers pointed telescopes at the sky, they have sought to see more. See farther and deeper. Space astronomy changed on April 24th 1990 with the launch of the space shuttle Discovery carrying aboard it the Hubble Space Telescope. A lot of people think we launched Hubble into space to get it closer to the stars but the real reason is the Earth's atmosphere both distorts and blocks light coming in from space. In space, beyond the atmosphere, the stars don't twinkle, instead they shine firm. That allows for the sensational images we've become accustomed to seeing from Hubble. But that wasn't Hubble's only benefit, it was also one of NASA's great observatories. There are many of these observatories in space but most are outfitted to answer one or two specific questions. Hubble was designed to be as inclusive as possible, it was supposed to answer as many questions as you could ask. At least as far as its design allowed. And Hubble succeeded very well at that. The Hubble Deep Field, perhaps the most important image ever taken by Hubble, shows us galaxies stretched all the way across the universe, up to ten billion light years away. Light that has taken billions of years to reach us in our corner of the universe, so we see these galaxies not that as they are today but as they were when the light left them. And in the end, after zooming in as much as possible, we see nothing...
