We discuss prospects for detecting a spectral break in γ-ray spectra of blazars due to the extragalactic background light (EBL) density falling off between the near and mid-IR. A measurable spectral change in the TeV spectra at 1 TeV could arise from a rapid or slow drop in the EBL density above ≈ 1 um. This effect is mediated by the ratio of the near to mid-IR density of EBL. A detection of su...

Nanoarchitected Materials In article number 2200039, Abdolhamid Akbarzadeh and co-workers present a perspective on devising the next generation of carbon-based nanoarchitected metamaterials through inspiration from biological design motifs. demonstrate promising instances for filling empty regions in material property charts to realize lightweight multifunctional advanced materials that may als...

We present the results of observations of the PSR B1509−58/MSH 15−52 system in X–rays (2 − 250 keV) by the Rossi X–ray Timing Explorer. The spectra of the peak of the pulsed component (radio phase 0.17 − 0.53) is fit by a power law of photon index 1.36 ± 0.01, with no evidence of a high energy spectral break seen up to ∼ 200 keV. For the off-pulse spectral component, the spectrum from 2 − 250 k...

Recently, laser scanning has been receiving greater attention as a useful tool for real-time 3D data acquisition, and various applications such as city modelling, DTM generation and 3D modelling of cultural heritage sites have been proposed. However, robust filtering systems for distinguishing onand off-terrain points from 3D point-cloud data collected by an airborne laser scanner still have ma...

Abstract The statistical power of weak lensing measurements is principally driven by the number high-redshift galaxies whose shapes are resolved. Conventional wisdom and physical intuition suggest this optimized deep imaging at long (red or near-IR) wavelengths, to avoid losing redshifted Balmer-break Lyman-break galaxies. We use synthetic Emission Line (“EL”)-COSMOS catalog simulate observatio...
