    • On Some Statistical Properties of GRBs with Measured Redshifts Having Peaks in Optical Light Curves 

      Autor: Beskin , Grigorii; Greco , Giuseppe; Oganesyan , Gor; Karpov , Sergey
      (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 ...

    • SEARCH FOR ISOLATED BLACK HOLES: PAST, PRESENT, FUTURE 

      Autor: Karpov , Sergey; Beskin , Grigory; Plokhotnichenko , Vladimir
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      The critical property of a black hole is the presence of an event horizon. It may be detected only by means of a detailed study of the emission features of its surroundings. The temporal resolution of such observations has ...

    • STATISTICAL PROPERTIES OF GRB AFTERGLOW PARAMETERS AS EVIDENCE OF COSMOLOGICAL EVOLUTION OF THEIR HOST GALAXIES 

      Autor: Beskin , Gregory; Oganesyan , Gor; Greco , Giuseppe; Karpov , Sergey
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      The results of a study of 43 peaked R-band light curves of optical counterparts of gamma-ray bursts with known redshifts are presented. The parameters of optical transients were calculated in the comoving frame, and then ...

    • 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. ...
