Multiwavelength campaign on Mrk 509. II. Analysis of high-quality Reflection Grating Spectrometer spectra
Galaxies: active – quasars: absorption lines – X-rays: general
2011/9/27
We study the bright Seyfert 1 galaxy Mrk~509 with the Reflection Grating Spectrometers (RGS) of XMM-Newton using the RGS multi-pointing mode of XMM-Newton for the first time in order to constrain the ...

The morphological and volumetric changes of a sandy beach were investigated through a series of two- monthly filed surveys carried out aver a 2-year period from April 2005 to January 2007. This paper ...
Blending Rudists with Technology; Non-destructive Examination of the Internal and External Structures of Rudists Using High Quality Scanning and Digital Imagery
External Structures Rudists Digital Imagery
2010/12/20
Certain formations within the Cretaceous of Texas include zones of silicified rudists. Such diagenetic alteration, combined with the timing of alteration, has preserved many structural features of the...
Symbiotic Optimization of the Nanolithography and RF-Plasma Etching for Fabricating High-Quality Light-Sensitive Superconductors on the 50 nm Scale
Symbiotic Optimization Nanolithography High-Quality Light-Sensitive Superconductors
2010/11/24
We present results of a fabrication-process development for the lithographic pattern transfer into the nm100sub range by combining electron-beam lithography and reactive dry etching to obtain ...
Fabrication and characterization of high quality factor silicon nitride nanobeam cavities
Fabrication characterization quality factor silicon nitride nanobeam cavities
2010/11/9
Si3N4 is an excellent material for applications of nanophotonics at visible wavelengths due to its wide bandgap and moderately large refractive index (n $\approx$ 2.0). We present the fabrication and ...
