Amplification of brightness variability by active-region nesting in Solar-like stars
(Iop Publishing Ltd, 2020)Kepler observations revealed that hundreds of stars with near-solar fundamental parameters and rotation periods have much stronger and more regular brightness variations than the Sun. Here we identify one possible reason ... -
Applications of a pnCCD detector coupled to columnar structure CsI(Tl) scintillator system in ultra high energy X-ray Laue diffraction
(Iop Publishing Ltd, 2017)Most charge coupled devices (CCDs) are made of silicon (Si) with typical active layer thicknesses of several microns. In case of a pnCCD detector the sensitive Si thickness is 450 mu m. However, for silicon based detectors ... -
Design criteria for a high energy Compton Camera and possible application to targeted cancer therapy
(Iop Publishing Ltd, 2015)The proposed research focuses on the design criteria for a Compton Camera with high spatial resolution and sensitivity, operating at high gamma energies and its possible application for molecular imaging. This application ... -
Modifying ultrafast optical response of sputtered VOX nanostructures in a broad spectral range by altering post annealing atmosphere
(Iop Publishing Ltd, 2015)Nanostructured VOX thin films were grown in a dc magnetron sputter system under two different Ar:O-2 gas flow ratios. The films were annealed under vacuum and various ratios of O-2/N-2 atmospheres. The insulator-to-metal ... -
A new spectroscopic imager for X-rays from 0.5 keV to 150 keV combining a pnCCD and a columnar CsI(Tl) scintillator
(Iop Publishing Ltd, 2017)By combining a low noise fully depleted pnCCD detector with a columnar CsI(Tl) scintillator an energy dispersive spatial resolving detector can be realized with a high quantum efficiency in the range from below 0.5 keV to ... -
Pantheon update on a model-independent analysis of cosmological supernova data
(Iop Publishing Ltd, 2020)We present an update of our previous work, necessitated by availability of a significantly improved dataset. The work is a model-independent analysis of the cosmological supernova (type Ia) data, where function families ...
