Radio Sources Toward Galaxy Clusters at 30 GHz

Kavli Affiliate: John Carlstrom | First 5 Authors: K. Coble, M. Bonamente, J. E. Carlstrom, K. Dawson, N. Hasler | Summary: Extra-galactic radio sources are a significant contaminant in cosmic microwave background and Sunyaev-Zel’dovich effect experiments. Deep interferometric observations with the BIMA and OVRO arrays are used to characterize the spatial, spectral, and flux distributions […]

Modeling Galaxy Clustering with Cosmological Simulations

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Andrey V. Kravtsov, , , , | Summary: I review recent progress in understanding and modeling galaxy clustering in cosmological simulations, with emphasis on models based on high-resolution dissipationless simulations. During the last decade, significant advances in our understanding of abundance and clustering of dark matter […]

The spaces of Laurent polynomials, $mathbb{P}^1$-orbifolds, and integrable hierarchies

Kavli Affiliate: Todor E. Milanov | First 5 Authors: Todor E. Milanov, Hsian-Hua Tseng, , , | Summary: Let $M_{k,m}$ be the space of Laurent polynomials in one variable $x^k + t_1 x^{k-1}+… t_{k+m}x^{-m},$ where $k,mgeq 1$ are fixed integers and $t_{k+m}neq 0$. According to B. Dubrovin cite{D}, $M_{k,m}$ can be equipped with a semi-simple […]

Cosmic Calibration

Kavli Affiliate: Katrin Heitmann | First 5 Authors: Katrin Heitmann, David Higdon, Charles Nakhleh, Salman Habib, | Summary: The complexity and accuracy of current and future precision cosmology observational campaigns has made it essential to develop an efficient technique for directly combining simulation and observational datasets to determine cosmological and model parameters; a procedure we […]

Gravitational Waves from Light Cosmic Strings: Backgrounds and Bursts with Large Loops

Kavli Affiliate: Craig J. Hogan | First 5 Authors: Craig J. Hogan, , , , | Summary: The mean spectrum and burst statistics of gravitational waves produced by a cosmological population of cosmic string loops are estimated using analytic approximations, calibrated with earlier simulations. Formulas are derived showing the dependence of observables on the string […]

Gromov–Witten Theory of CP^1 and Integrable Hierarchies

Kavli Affiliate: Todor E. Milanov | First 5 Authors: Todor E. Milanov, , , , | Summary: The ancestor Gromov–Witten invariants of a compact {Kahler} manifold $X$ can be organized in a generating function called the total ancestor potential of $X$. In this paper, we construct Hirota Quadratic Equations (HQE shortly) for the total ancestor […]
