Black Hole Results from XMM-Newton
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)XMM-Newton is one of the most successful science missions of the European Space Agency. Since 2003 every year about 300 articles are published in refereed journals making directly use of XMM-Newton data. All XMM-Newton ... -
Clustering Measurements of broad-line AGNs: Review and Future
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Despite substantial effort, the precise physical processes that lead to the growth of super-massive black holes in the centers of galaxies are still not well understood. These phases of black hole growth are thought to be ... -
Concluding Address
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Before I offcially conclude this workshop - far be it from me to attempt to compete with some concluding remarks already delivered at the meeting with various levels of passion by Gennady Bisnovatyi-Kogan, Giulio Auriemma ... -
Concluding Remarks
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Short comments to the conference talks. -
Cosmological Evolution of the Central Engine in High-Luminosity, High-Accretion Rate AGN
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)In this paper I discuss the status of observational studies aiming at probing the cosmological evolution of the central engine in high-luminosity, high-accretion rate Active Galactic Nuclei (AGN). X-ray spectroscopic ... -
Data Analysis of Globular Cluster Harris Catalogue in View of the King Models and Their Dynamical Evolution. I. Theoretical model
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We discuss the possibility to analyze the problem of gravothermal catastrophe in a new way, by obtaining thermodynamical equations to apply to a selfgravitating system. By using the King distribution function in the framework ... -
Data Analysis of Globular Cluster Harris Catalogue in View of the King Models and Their Dynamical Evolution. II. Observational Evidences
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We summarize some observational comparison concerning the features of globular clusters (GCs) population in connection to the evolution of King models. We also make a comparison with some extragalactic GCs systems, in order ... -
Design and Tests of the Hard X-ray Polarimeter X-Calibur
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)X-ray polarimetry promises to give qualitatively new information bout high-energy astrophysical sources, such as binary black hole systems, micro-quasars, active galactic nuclei, and gamma-ray bursts. We designed, built ... -
Electron Acceleration in Supernovae and Millimeter Perspectives
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Supernovae launch a strong shock wave by the interaction of the expanding ejecta and surrounding circumstellar matter (CSM). At the shock, electrons are accelerated to relativistic speed, creating observed synchrotron ... -
Evolution of Massive Population III Stars
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)While the evolution of massive stars in the local Universe is dominated by mass-loss, the evolution of massive Population III stars should be dominated by rotation. An important effect of rotation is rotationally-induced ... -
Expected Hard X-Ray and Soft Gamma-Ray from Supernovae
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)High energy emissions from supernovae (SNe), originated from newly formed radioactive species, provide direct evidence of nucleosynthesis at SN explosions. However, observational diculties in the MeV range have so far ... -

First Hints of Pressure Waves in a Helical Extragalactic Jet: S5 0836+710
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)One of the open questions in extragalactic jet Astrophysics is related to the nature of the observed radio jet, namely whether it traces a pattern or the flow structure itself. In this paper I summarize the evidence collected ... -
Forty Years of X-Raying Narrow-Line Seyfert 1 Galaxies
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Forty years after the discovery of Narrow-Line Seyfert 1 Galaxies (NLS1s), and 20 years since the discovery of the remarkable ultrasoft soft X-ray emissions of NLS1s, strategic publications improved the understanding of ... -
Fullerenes, PAHs, Amino Acids and High Energy Astrophysics
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We present theoretical, observational and laboratory work on the spectral properties of fullerenes and hydrogenated fullerenes. Fullerenes in its various forms (individual, endohedral, hydrogenated, etc.) can contribute ... -
Gamma-rays, Neutrinos and Particle Astronomy as Messengers of the Universe
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Observations of charged cosmic-rays, γ-rays and neutrino are possible thanks to the availability of new detectors coming from technologies typical of experimental particle physics. In conjunction with more traditional ... -
Gravitational Waves and Dark Energy
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)The idea that dark energy is gravitational waves may explain its strength and its time-evolution. A possible concept is that dark energy is the ensemble of coherent bursts (solitons) of gravitational waves originally ... -
HAVmS: Highly Available Virtual Machine Computer System Fault Tolerant with Automatic Failback and Close to Zero Downtime
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)In scientic computing, systems often manage computations that require continuous acquisition of of satellite data and the management of large databases, as well as the execution of analysis software and simulation models ... -
High-Resolution X-Ray Spectroscopy of Galactic Supernova Remnants
