Three-point Correlation functions of Giant magnons with finite size
Changrim Ahn, Plamen Bozhilov
We compute holographic three-point correlation functions or structure constants of a zero-momentum dilaton operator and two (dyonic) giant magnon string states with a finite-size l…
Limits on Dark Radiation, Early Dark Energy, and Relativistic Degrees of Freedom
Erminia Calabrese, Dragan Huterer, Eric V. Linder +2
Recent cosmological data analyses hint at the presence of an extra relativistic energy component in the early universe. This component is often parametrized as an excess of the eff…
A note on the role of the boundary terms for the non-Gaussianity in general k-inflation
Frederico Arroja, Takahiro Tanaka
In this short note we clarify the role of the boundary terms in the calculation of the leading order tree-level bispectrum in a fairly general minimally coupled single field inflat…
Dynamics of stringy congruence in early universe
Yong Seung Cho, Soon-Tae Hong
We studied the singularity of the geodesic surface congruence for timelike and null strings using the expansion of the universe in the string theory. We had Raychaudhuri type equat…
Cosmic-Ray Proton and Helium Spectra from the First CREAM Flight
Y. S. Yoon, H. S. Ahn, P. S. Allison +31
Cosmic-ray proton and helium spectra have been measured with the balloon-borne Cosmic Ray Energetics And Mass experiment flown for 42 days in Antarctica in the 2004-2005 austral su…
Correlated Supernova Systematics and Ground Based Surveys
Alex G. Kim, Eric V. Linder
Supernova distances provide a direct probe of cosmic acceleration, constraining dark energy. This leverage increases with survey redshift depth at a rate bounded by the systematic…
