Cosmic Sparks from Superconducting Strings

The work of Tanmay Vachaspati, Visitor in the School of Natural Sciences, has been published in Physical Review Letters (101, 141301, September 29, 2008). "Cosmic Sparks from Superconducting Strings" explores Vachaspati's investigation of cosmic sparks from cusps on superconducting cosmic strings in light of the recently discovered millisecond radio burst by Lorimer et al.  Vachaspati's work has also been highlighted on PhysOrg.com in an article titled, "Cosmic Strings Might Emit Cosmic Sparks, Answer Cosmological Questions."
