Investigating reciprocity failure in 1.7-micron cut-off HgCdTe detectors

Kavli Affiliate: Tomasz Biesiadzinski | First 5 Authors: Michael Schubnell, Tomasz Biesiadzinski, Wolfgang Lorenzon, Robert Newman, Greg Tarle | Summary: Flux dependent non-linearity (reciprocity failure) in HgCdTe NIR detectors with 1.7 micron cut-off was investigated. A dedicated test station was designed and built to measure reciprocity failure over the full dynamic range of near infrared […]

Comments on arXiv:1006.0972 “XENON10/100 dark matter constraints in comparison with CoGeNT and DAMA: examining the Leff dependence”

Kavli Affiliate: Juan I. Collar | First 5 Authors: J. I. Collar, , , , | Summary: Savage et al. have recently put forward the claim that results from the XENON10 experiment are incompatible with the totality of both DAMA/LIBRA and CoGeNT experimental regions. In this brief note the source of this erroneous conclusion is […]

ROMA (Rank-Ordered Multifractal Analysis) for intermittent fluctuations with global crossover behavior

Kavli Affiliate: Tom Chang | First 5 Authors: Sunny W. Y. Tam, Tom Chang, Paul M. Kintner, Eric M. Klatt, | Summary: Rank-Ordered Multifractal Analysis (ROMA), a recently developed technique that combines the ideas of parametric rank ordering and one parameter scaling of monofractals, has the capabilities of deciphering the multifractal characteristics of intermittent fluctuations. […]

Groups of Galaxies at Intermediate Redshift

Kavli Affiliate: Catherine Grant | First 5 Authors: Eric D. Miller, Marshall Bautz, Catherine Grant, Ryan Hickox, Mark Brodwin | Summary: Galaxy groups are key tracers of galaxy evolution, cluster evolution, and structure formation, yet they are difficult to study at even moderate redshift. We have undertaken a project to observe a flux-limited sample of […]

Decade time-scale modulation of low mass X-ray binaries

Kavli Affiliate: Alan Levine | First 5 Authors: Martin Durant, Remon Cornelisse, Ron Remillard, Alan Levine, | Summary: Regular observations by the All Sky Monitor aboard the Rossi X-ray Timing Explorer satellite have yielded well-sampled light-curves with a time baseline of over ten years. We find that up to eight of the sixteen brightest persistent […]

Broad-Band Soft X-ray Polarimetry

Kavli Affiliate: Ralf Heilmann | First 5 Authors: Herman L. Marshall, Ralf Heilmann, Norbert Schulz, Kendrah Murphy, | Summary: We developed an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors. The intensity variation with position […]
