Multiple Soft Limits of Cosmological Correlation Functions

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 […]

Fifteen years of the Advanced CCD Imaging Spectrometer

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 […]

Large-area Reflective Infrared Filters for Millimeter/sub-mm Telescopes

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: Z. Ahmed, J. A. Grayson, K. L. Thompson, C. L. Kuo, G. Brooks | Summary: Ground-based millimeter and sub-millimeter telescopes are attempting to image the sky with ever-larger cryogenically-cooled bolometer arrays, but face challenges in mitigating the infrared loading accompanying large apertures. Absorptive infrared filters supported by […]

A framework for modeling the detailed optical response of thick, multiple segment, large format sensors for precision astronomy applications

Kavli Affiliate: Steven Kahn | First 5 Authors: Andrew Rasmussen, Pierre Antilogus, Pierre Astier, Chuck Claver, Peter Doherty | Summary: Near-future astronomical survey experiments, such as LSST, possess system requirements of unprecedented fidelity that span photometry, astrometry and shape transfer. Some of these requirements flow directly to the array of science imaging sensors at the […]

The Heavy Photon Search Test Detector

Kavli Affiliate: Homer Neal | First 5 Authors: Marco Battaglieri, Sergey Boyarinov, Stephen Bueltmann, Volker Burkert, Andrea Celentano | Summary: The Heavy Photon Search (HPS), an experiment to search for a hidden sector photon in fixed target electroproduction, is preparing for installation at the Thomas Jefferson National Accelerator Facility (JLab) in the Fall of 2014. […]

Delensing Galaxy Surveys

Kavli Affiliate: Chihway Chang | First 5 Authors: Chihway Chang, Bhuvnesh Jain, , , | Summary: Weak gravitational lensing can cause displacements, magnification, rotation and shearing of the images of distant galaxies. Most studies focus on the shear and magnification effects since they are more easily observed. In this paper we focus on the effect […]

Statistics of Dark Matter Substructure: II. Comparison of Model with Simulation Results

Frank C. van den Bosch, Fangzhou Jiang, , , | Summary: [[{“value”:”We compare subhalo mass and velocity functions obtained from different simulations with different subhalo finders among each other, and with predictions from the new semi-analytical model of Jiang & van den Bosch (2014). We find that subhalo mass functions (SHMFs) obtained using different subhalo […]

Complexity Phenomena and ROMA of the Magnetospheric Cusp, Hydrodynamic Turbulence, and the Cosmic Web

Kavli Affiliate: Tom Chang | First 5 Authors: Tom Chang, Cheng-chin Wu, Marius Echim, Herve Lamy, Mark Vogelsberger | Summary: Dynamic Complexity is a phenomenon exhibited by a nonlinearly interacting system within which multitudes of different sizes of large scale coherent structures emerge, resulting in a globally nonlinear stochastic behavior vastly different from that could […]
