Kavli Affiliate: Catherine E. Grant | First 5 Authors: Catherine E. Grant, Matteo Guainazzi, Lorenzo Natalucci, Jukka Nevalainen, Paul P. Plucinsky | Summary: We present the main results of the 8th International Astronomical Consortium for High Energy Calibration (IACHEC) meeting, held in Theddingworth, Leicestershire, between March 25 and 28, 2013. Over 50 scientists directly involved […]
Kavli Affiliate: Emil Martinec | First 5 Authors: Peter Adshead, Emil Martinec, Mark Wyman, , | Summary: Chromo-Natural Inflation is the first worked example of a model of inflation in which slow-roll inflation is achieved by "magnetic drift" as opposed to Hubble friction. In this work, we give an account of the perturbations at linear […]
Kavli Affiliate: W. L. Kimmy Wu | First 5 Authors: Jannis Bielefeld, W. L. Kimmy Wu, Robert R. Caldwell, Olivier Dore, | Summary: A phenomenological model of dark energy that tracks the baryonic and cold dark matter at early times but resembles a cosmological constant at late times is explored. In the transition between these […]

Kavli Affiliate: Sarah N. T. Heine | First 5 Authors: John Rutherford, Daniel Dewey, Enectali Figueroa-Feliciano, Sarah N. T. Heine, Fabienne A. Bastien | Summary: We present the analysis of 21 bright X-ray knots in the Cassiopeia A supernova remnant from observations spanning 10 yr. We performed a comprehensive set of measurements to reveal the […]
Kavli Affiliate: Kentaro Hori | First 5 Authors: Francesco Benini, Richard Eager, Kentaro Hori, Yuji Tachikawa, | Summary: We compute the elliptic genera of two-dimensional N=(2,2) and N=(0,2) gauged linear sigma models via supersymmetric localization, for rank-one gauge groups. The elliptic genus is expressed as a sum over residues of a meromorphic function whose argument […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Ofer Aharony, Nathan Seiberg, Yuji Tachikawa, , | Summary: Starting with a choice of a gauge group in four dimensions, there is often freedom in the choice of magnetic and dyonic line operators. Different consistent choices of these operators correspond to distinct physical theories, with the same […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Starting with a choice of a gauge group in four dimensions, there is often freedom in the choice of magnetic and dyonic line operators. Different consistent choices of these operators correspond to distinct physical theories, with the same correlation functions […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Henrique S. Xavier, Ravi R. Gupta, Masao Sako, Chris B. D’Andrea, Joshua A. Frieman | Summary: We used the GMBCG galaxy cluster catalogue and SDSS-II supernovae data with redshifts measured by the BOSS project to identify 48 SNe Ia residing in rich galaxy clusters and compare […]
Kavli Affiliate: James Chiang | First 5 Authors: Jeffrey D. Scargle, Jay P. Norris, Brad Jackson, James Chiang, | Summary: This presentation describes the Bayesian Block algorithm in the context of its application to analysis of time series data from the Fermi Gamma Ray Space Telescope. More generally this algorithm performs optimal segmentation analysis on […]
