Kavli Affiliate: Keith C. Schwab | First 5 Authors: Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer, Peter F. Barker, Angelo Bassi | Summary: Do the laws of quantum physics still hold for macroscopic objects – this is at the heart of Schr"odinger’s cat paradox – or do gravitation or yet unknown effects set a limit for […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Ashok T. Ramu, John E. Bowers, , , | Summary: The mean-free path (MFP) accumulation function for the effective thermal conductivity, introduced by Dames and Chen is a compact, universal and highly useful summary of the effect of ballistic thermal transport on the effective thermal conductivity […]
Kavli Affiliate: Elise Jennings | First 5 Authors: Elise Jennings, David Jennings, , , | Summary: The linear growth rate is commonly defined through a simple deterministic relation between the velocity divergence and the matter overdensity in the linear regime. We introduce a formalism that extends this to a nonlinear, stochastic relation between $θ= nabla […]
Kavli Affiliate: Bradford Benson | First 5 Authors: Henry W. Lin, Michael McDonald, Bradford Benson, Eric Miller, | Summary: Sunyaev-Zeldovich (SZ) surveys find massive clusters of galaxies by measuring the inverse Compton scattering of cosmic microwave background off of intra-cluster gas. The cluster selection function from such surveys is expected to be nearly independent of […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Miguel Molerón, Chiara Daraio, , , | Summary: Lenses that can collect the perfect image of an object must restore propagative and evanescent waves. However, for efficient information transfer, e.g., in compressed sensing, it is often desirable to detect only the fast spatial variations of the wave […]
Kavli Affiliate: Robert Goeke | First 5 Authors: Natasha Hurley-Walker, Melanie Johnston-Hollitt, Ron Ekers, Richard Hunstead, Elaine M. Sadler | Summary: Recent observations with the Murchison Widefield Array at 185~MHz have serendipitously unveiled a heretofore unknown giant and relatively nearby ($z = 0.0178$) radio galaxy associated with NGC,1534. The diffuse emission presented here is the […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong, Deborah Bard, Emmanuel Bertin | Summary: We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravitational lensing shear distortions from simulated galaxy images. […]
Kavli Affiliate: Rebecca A. Masterson | First 5 Authors: Niraj K. Inamdar, Richard P. Binzel, Jae Sub Hong, Branden Allen, Jonathan Grindlay | Summary: OSIRIS-REx is the third spacecraft in the NASA New Frontiers Program and is planned for launch in 2016. OSIRIS-REx will orbit the near-Earth asteroid (101955) Bennu, characterize it, and return a […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Austin Joyce, Justin Khoury, Marko Simonović, , | Summary: We derive novel identities satisfied by inflationary correlation functions in the limit where two external momenta are taken to be small. We derive these statements in two ways: using background-wave arguments and as Ward identities following from the […]
Kavli Affiliate: Peter G. Ford | First 5 Authors: Catherine E. Grant, Mark W. Bautz, Peter G. Ford, Paul P. Plucinsky, | Summary: As the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory enters its fifteenth year of operation on orbit, it continues to perform well and produce spectacular scientific results. The response […]
