Biomimetics and astronomical X-ray optics
Autor: Hudec R.; Remisova K.
(Astronomical Institute, Slovak Academy of Sciences, 2017)Some sea and water animals have strange mirror eyes which have (or might have) potential application in science and technology in general and in X-ray astrophysics in particular. While the principles of mirror eyes of ... -
Digitized Astronomical Photographic Archives as Large Area Sky Survey of Large Amount of Astronomical Data
Autor: Hudec R.
(SISSA-The International School for Advanced Studies, 2014)We report here on an investigation of astronomical plate archives and tests of the scanning devices for digitization of archival astronomical plates. These archives represent huge database of historical astronomical data, ... -
Fish eye optics
Autor: Hudec R.; Michalova S.
(Astronomical Institute, Slovak Academy of Sciences, 2017)We report on small student (high school) project of the Czech Academy of Sciences dealing with animal (fish) eyes and possible application in science and technology. Albeit most fishes have refractive eyes, the recent ... -
GLObal Robotic telescopes Intelligent Array for e-Science
Autor: Hudec R.
(SISSA-The International School for Advanced Studies, 2014)We report here on the ongoing EU FP7 Project GLORIA with emphasis on possibility of investigation of cataclysmic variables by users. GLORIA stands for GLObal Robotic-telescopes Intelligent Array. GLORIA enables the first ... -
Kirkpatrick Baez X-ray optics for astrophysics: Recent status
Autor: Hudec R.; Pína L.; Maršíková V.; Nentvich O.; Urban M.; Inneman A.
(Astronomical Institute, Slovak Academy of Sciences, 2018)X-ray optics in Kirkpatrick Baez arrangement represent promising alternative to Wolter optics in common use. We present briefly recent status of design, developments, and tests of this kind of X–ray optics including ... -
Lobster Eye X-ray optics for astrophysics: Recent status
Autor: Hudec R.; Pína L.; Maršíková V.; Nentvich O.; Urban M.; Inneman A.
(Astronomical Institute, Slovak Academy of Sciences, 2018)X-ray optics in Lobster Eye arrangement represent promising complementary device to narrow field X-ray optics in common use. We present briefly recent status of design, developments, and tests of X-ray optics including ... -
Lobster-Eye All-Sky Soft X-ray Monitors
Autor: Tichý V.; Hudec R.; Šimon V.
(SISSA/ISAS, 2015)The idea of a satellite providing monitoring of specified sky areas in soft X-rays is presented. Observation plan could include also e.g. searching for X-ray afterglows of gamma-ray bursts. The spacecraft could be of the ... -
Long gamma-ray bursts in the Swift era: the color indices of their optical afterglows
Autor: Šimon V.; Hudec R.; Pizzichini G.
(SISSA/ISAS, 2015)We present an analysis of optical afterglows (OAs) of long GRBs which were mostly discovered by NASA Swift. We used the method of the color indices that uses the commonly available multiband photometry. We show that for ... -
New Perspectives in Multispectral Sky Monitoring
Autor: Hudec R.
(SISSA/ISAS, 2015)I give a short review and discussion of multispectral (optical and X–rays) sky monitoring. -
Scientific astrophysical payloads for pico and nano-satellites
Autor: Hudec R.; Simon V.; Tichý V.
(SISSA-The International School for Advanced Studies, 2014)The picosatellites, recently in development at many institutes and universities (e.g. Schmidt et al. 2009 and Schilling 2006), require a miniaturized payload. We present and discuss an idea for a suitable scientific payload, ... -
