Lobster Eye X-ray optics for astrophysics: Recent status

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 modules developed and tested within recent space project

Attendance at home matches of FK Dukla Praha

Název: Návštěvnost na domácích ligových utkáních FK Dukla Praha Cíle: Hlavním cílem této práce je na základě marketingového výzkumu navrhnout doporučení vedoucí ke zvýšení návštěvnosti na fotbalových utkání FK Dukla Praha. Cíl práce je koncipován ve spolupráci s klubem FK Dukla Praha tak, aby mu poskytl cenné údaje o jeho návštěvnících a jejich spokojenosti s nabízenými službami. Metody: Metodou použitou v této práci je marketingový výzkum. Jeho hlavní část tvořilo elektronické dotazování prostřednictvím dotazníku vytvořeného pro účely této práce. Dotazování bylo dále doplněno polostrukturovaným rozhovorem se zaměstnancem marketingového oddělení FK Dukla Praha. Výsledky: Výsledky tohoto výzkumu odhalily několik možností, kterými by bylo možné zvýšit návštěvnost na domácích utkáních FK Dukla Praha. Jedná se především o zkvalitnění nabízených služeb, přizpůsobení se fanouškům a nabídku speciálních akcí. Klíčová slova: fotbal, diváci, fanoušci, stadion, marketingový výzkumTitle: Attendance at home matches of FK Dukla Praha Objectives: The main objective of this thesis is to find ways of improving attendance at home matches of FK Dukla Praha based on data from marketing research.

Lobster X-ray All Sky Monitor—Novel experiment for monitoring GRBs and XRFs

We present a brief review of the X-ray All-Sky Monitor (ASM) based on Lobster Eye(LE) optics. Thesyste m will observe the Whole sky in soft X-rays with the limiting flux up to two orders of magnitude better than current ASMs

Novel X-ray telescopes for wide-field X-ray monitoring

We report on fully innovative very wide-field of view X-ray telescopes with high sensitivity as well as large field of view. The prototypes are very promising, allowing the proposals for space projects with very wide-field Lobstereye X-ray optics to be considered. The novel telescopes will monitor the sky with unprecedented sensitivity and angular resolution of order of 1 arcmin. They are expected to contribute essentially to study and to understand various astrophysical objects such as AGN, SNe, Gamma-ray bursts (GRBs), X-ray flashes (XRFs), galactic binary sources, stars, CVs, X-ray novae, various transient sources, etc. The Lobster optics based X-ray All Sky Monitor is capable to detect around 20 GRBs and 8 XRFs yearly and this will surely significantly contribute to the related science

Czech Contribution to Athena

We describe the recent status of the Czech contribution to the ESA Athena space mission, with emphasis on the development of new technologies and test samples of X-ray mirrors with precise surfaces, based on new materials, and their applications in space. In addition, alternative X-ray optical arrangements are investigated, such as Kirkpatrick-Baez systems

Czech Participation in International X-Ray Observatory (IXO)

Here we describe the recent status of Czech participation in the IXO (International X-ray Observatory) space mission, with emphasis on the development of new technologies and test samples of X-ray mirrors with precise surfaces, based on new materials, and their applications in space. In addition, alternative X-ray optical arrangements are investigated, such as Kirkpatrick-Baez systems

The Czech Contribution to Future Large X-Ray Astronomy Telescopes: Recent Progress

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 new materials and alternative designs. We report on further investigations and tests of X-ray optical arrangements, such as Kirkpatrick-Baez systems and Multi-Foil Optics

Lobster eye optics for nano-satellite x-ray monitor

The Lobster eye design for a grazing incidence X-ray optics provides wide field of view of the order of many degrees, for this reason it would be a convenient approach for the construction of space X-ray monitors. In this paper, we compare previously reported measurements of prototype lobster eye X-ray optics called P-25 with computer simulations and discuss differences between the theoretical end experimentally obtained results. Usability of this prototype lobster eye and manufacturing technology for the nano-satellite mission is assessed. The specific scientific goals are proposed
