On Some Statistical Properties of GRBs with Measured Redshifts Having Peaks in Optical Light Curves
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We studied the subset of optical light curves of gamma-ray bursts with measured redshifts and well-sampled R band data that have clearly detected peaks. Among 43 such events, 11 are promptoptical peaks (P), coincident with ... -
Photometric Analysis of Pi of the Sky Data
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Two fully automatic Pi of the Sky detectors with a large field of view, located in Spain (INTA) and in Chile (SPDA) observe the sky in search of rare optical phenomena, and also collect observations which include many kinds ... -
Status and Perspectives of the Mini-MegaTORTORA Wide-field Monitoring System with High Temporal Resolution
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Here we briefly summarize our long-term experience of constructing and operating wide-field monitoring cameras with sub-second temporal resolution to look for optical components of GRBs, fast-moving satellites and meteors. ... -
Study of Silicon Photomultipliers for the GRIPS Calorimeter Module
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)GRIPS is a proposed gamma-ray (200 keV to 80 MeV) astronomy mission, which incorporates a pair-creation and Compton scattering telescope, along with X-ray and infrared telescopes. It will carry out a sensitive all-sky ... -
The Czech Contribution to Future Large X-Ray Astronomy Telescopes: Recent Progress
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We briefly review the recent status of the Czech contribution to future space X-ray astronomy missions with emphasis on the development of new technologies and test samples of X-ray mirrors with precise surfaces based on ... -
The Point Spread Function Variations inside Wide-field Astonomical Images
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The Point Spread Function (PSF) of the astronomical imaging system is usually approximated by a Gaussian or Moffat function. For simplification, the astronomical imaging system is considered to be time and space invariant. ...
