Vorton construction and dynamics
Richard Battye, Paul Sutcliffe
Vortons are closed loops of superconducting cosmic strings carrying current and charge. In this paper we present the first numerical construction of vortons in the global version o…
The Quijote CMB Experiment
J. A. Rubino-Martin, R. Rebolo, M. Tucci +37
We present the current status of the QUIJOTE (Q-U-I JOint TEnerife) CMB Experiment, a new instrument which will start operations early 2009 at Teide Observatory, with the aim of ch…
Textures and Semi-Local Strings in SUSY Hybrid Inflation
Richard A. Battye, Bjorn Garbrecht, Apostolos Pilaftsis
Global topological defects may account for the large cold spot observed in the Cosmic Microwave Background. We explore possibilities of constructing models of supersymmetric F-term…
Kinky Vortons
Richard Battye, Paul Sutcliffe
Cosmic vortons are closed loops of superconducting cosmic strings carrying current and charge. Despite a large number of studies the existence and stability of cosmic vorton soluti…
Detecting the B-mode Polarisation of the CMB with Clover
C. E. North, B. R. Johnson, P. A. R. Ade +41
We describe the objectives, design and predicted performance of Clover, which is a ground-based experiment to measure the faint ``B-mode'' polarisation pattern in the cosmic microw…
Observations of the Corona Borealis supercluster with the superextended Very Small Array: further constraints on the nature of the non-Gaussian CMB cold spot
Ricardo Genova-Santos, Jose Alberto Rubino-Martin, Rafael Rebolo +16
We present interferometric imaging at 33 GHz, with the new superextended configuration of the Very Small Array (VSA), of a very deep decrement in the cosmic microwave background (C…
