Cornell Cosmic, Spring 2018
No full textOur purpose is to inform the Cornell Community of contemporary developments in outer space, whether it be through scientific advancements or the changing dynamics in international relations. We hope to foster a futuristic mindset by emphasizing the search for new life as well as the possibility of inhabiting planets other than Earth. Furthermore, we seek to investigate how outer space operations reflect the shifting dynamics among countries on Earth. Through intertwining these various elements we offer you a holistic representation of our newest frontier

Relativistic scalar charged particle in a rotating cosmic string space-time with Cornell-type potential and Aharonov-Bohm effect
No full textIn this paper, we study the Klein-Gordon equation subject to a magnetic quantum flux in the presence of a Cornell-type scalar and Coulomb-type vector potentials in a rotating cosmic string space-time. We solve the radial wave equation and evaluate the energy eigenvalues and eigenfunctions and analyze a relativistic analogue of Aharonov-Bohm effect for bound states
Klein–Gordon field in spinning cosmic-string space-time with the Cornell potential
No full text We study the relativistic quantum dynamics of a Klein–Gordon scalar field subject to a Cornell potential in spinning cosmic-string space-time, in order to better understand the effects of gravitational fields produced by topological defects on the scalar field. We solve the Klein–Gordon equation in the presence of scalar and vector interactions by utilizing the Nikiforov–Uvarov formalism and two ansätze, one of which leads to a biconfluent Heun differential equation. We obtain the wave-functions and the energy levels of the relativistic field in that space-time. We discuss the effect of various physical parameters and quantum numbers on the wave-functions. </jats:p
Alignment of the CMS silicon strip tracker during stand-alone commissioning
No full textThis is the Pre-print version of the Article. The official published version of the paper can be accessed from the link below - Copyright @ 2009 IOPThe results of the CMS tracker alignment analysis are presented using the data from cosmic tracks, optical survey information, and the laser alignment system at the Tracker Integration Facility at CERN. During several months of operation in the spring and summer of 2007, about five million cosmic track events were collected with a partially active CMS Tracker. This allowed us to perform first alignment of the active silicon modules with the cosmic tracks using three different statistical approaches; validate the survey and laser alignment system performance; and test the stability of Tracker structures under various stresses and temperatures ranging from +15C to -15C. Comparison with simulation shows that the achieved alignment precision in the barrel part of the tracker leads to residual distributions similar to those obtained with a random misalignment of 50 (80) microns in the outer (inner) part of the barrel.This work has been supported by: the Austrian Federal Ministry of Science and Research; the Belgium Fonds de la Recherche Scientifique and Fonds voor Wetenschappelijk Onderzoek; the Academy of Finland and

Joseph Cornell and astronomy a case for the stars
No full textThis book provides an in depth look at one artist's intense fascination with the science of astronomy. Joseph Cornell (1903-72) has often been viewed as a recluse, isolated in his home on Utopia Parkway, lost in the fairy tales and charming objects of his collages and assemblage boxes. Less commonly known has been Cornell's vested and serious interest in the history of astronomy and the cutting-edge discoveries made during his own lifetime. An avid reader, he amassed a library of books and articles about science and astronomy, and his reflections about these subjects had a direct impact on his art. This book explores why astronomy captivated Cornell, and considers hundreds of his works: found-footage films, three-dimensional space-object boxes, enigmatic collages, and cosmic ephemera, that contain references to astronomical phenomena. The author considers Cornell's enormous collection of astronomy materials, ranging from eighteenth-century books to recent works; newspaper and magazine articles that Cornell clipped and sorted; and diary entries of his observations while stargazing in his backyard. She examines how Cornell explored many dimensions of astronomy through his identities as a Christian Scientist and surrealist artist. Unfolding Cornell's work with depth and breadth, this work offers a convincing and original appreciation of this intriguing American artist

Cosmic Superstrings: Observable Remnants of Brane Inflation
No full textBrane inflation provides a natural dynamical model for the physics which underlie the inflationary paradigm. Besides their inflationary predictions, brane models imply another observable consequence: cosmic strings. In this dissertation I outline the background of how cosmic strings arise in brane inflationary models and how the properties of the strings and the models are mutually tied (Chapter 2). I then use cosmological observations to put limits on the properties of any actually-existing cosmic string network (Chapter 3). Next, I study the question of how cosmic superstrings, as the cosmic strings arising from string theory are known, could be distinct from classical gauge-theory cosmic strings. In particular, I propose an analytical model for the cosmological evolution of a network of binding cosmic strings (Chapter 4); I also describe the distinctive gravitational lensing phenomena that arecaused by binding strings (Chapter 5). Finally, I lay out the background for the numerical study of a gauge theory model forthe dynamics of cosmic superstring binding (Chapter 6)
Effects of Kaluza-Klein Theory and Potential on a Generalized Klein-Gordon Oscillator in the Cosmic String Space-Time
No full textIn this paper, we solve a generalized Klein-Gordon oscillator in the cosmic string space-time with a scalar potential of Cornell-type within the Kaluza-Klein theory and obtain the relativistic energy eigenvalues and eigenfunctions. We extend this analysis by replacing the Cornell-type with Coulomb-type potential in the magnetic cosmic string space-time and analyze a relativistic analogue of the Aharonov-Bohm effect for bound states
