    • Status and Perspectives of the Mini-MegaTORTORA Wide-field Monitoring System with High Temporal Resolution 

      Autor: Karpov , Sergey; Beskin , Grigory; Bondar , Sergey; Perkov , Alexey; Ivanov , Evgeny; Guarnieri , Adriano; Bartolini , Corrado; Greco , Giuseppe; Shearer , Andy; Sasyuk , Vyacheslav
      (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 

      Autor: Ulyanov , Alexei; Hanlon , Lorraine; McBreen , Sheila; Foley , Suzanne
      (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 

      Autor: Hudec , René; Pína , Ladislav; Inneman , Adolf; Černá , Daniela; Maršíková , Veronika; Tichý , Vladimír; Míka , Martin
      (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 

      Autor: Anisimova , Elena; Bednář , Jan; Páta , Petr
      (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. ...
