A Multi-Wavelength View of the XMM-Newton Galactic Plane
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We present an X-ray survey of the Galactic Plane conducted by the Survey Science Centre of the XMM-Newton satellite. The survey contains more than 1300 X-ray detections at low and intermediate Galactic latitudes and covering ... -
A Novel Approach in the WIMP Quest: Cross-Correlation of Gamma-Ray Anisotropies and Cosmic Shear
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We present the cross-correlation angular power spectrum of cosmic shear and gamma-rays produced by the annihilation/decay of Weakly Interacting Massive Particle (WIMP) dark matter (DM), and by astrophysical sources. We ... -
A Review of Astrophysical Jets
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Astrophysical jets are ubiquitous: this simple statement has become a commonplace over the last three decades and more as a result of observing campaigns using detectors sensitive from radio to gamma-ray energies. During ... -
Active Galactic Nuclei: Jets as the Source of Hadrons and Neutrinos
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Active galactic nuclei are extragalactic sources, and their relativistic hot-plasma jets are believed to be the main candidates of the cosmic-ray origin, above the so-called knee region of the cosmic-ray spectrum. Relativistic ... -
AGILE Highlights after Six Years in Orbit
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)AGILE is an ASI space mission in collaboration with INAF, INFN and CIFS, dedicated to the observation of the gamma-ray Universe in the 30 MeV - 50 GeV energy range, with simultaneous X-ray imaging capability in the 18-60 ... -
AGN/Starburst Connection
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Two main physical processes characterize the activity in the nuclear region of active galaxies: an intense star formation (starburst, SB) and an Active Galactic Nucleus (AGN). While the existence of a starburst-AGN connection ... -
Are Supernovae Responsible for the Gamma Ray Spectrum from the Galactic Center?
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We discuss the supernova remnants distribution as a function of the galactic longitude and compare their positions to that of the detected TeV gamma ray sources. A large fraction of these sources either coincide or a close ... -
ARGO-YBJ: Highlights and Prospects
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)The ARGO-YBJ experiment has been in stable data taking for 5 years at the YangBaJing Cosmic Ray Laboratory (Tibet, P.R. China, 4300 m a.s.l., 606 g/cm2). With a duty-cycle greater than 86% the detector collected about 51011 ... -
Astrophysics Without Black Holes, and Without Extragalactic Gamma-Ray Bursts
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Contrary to common belief, it is argued that our Universe contains neither Black Holes, nor Extracalactic Gamma-Ray Bursts. -
Atmosphere-Space Interactions Monitor (ASIM): State of the Art
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Atmosphere-Space Interactions Monitor (ASIM) mission is an ESA pay load which will be installed in the Columbus module of the International Space Station (ISS). ASIM is optimized to the observation and monitoring of ... -
Auger Highlights
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)The Pierre Auger Observatory has been designed to investigate the origin and nature of the ultra high energy cosmic rays using a hybrid detection technique. A review of selected results is presented, with the emphasis given ... -
Be/X-Ray Binaries with Black Holes in the Galaxy and in the Magellanic Clouds
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)I will start with the statistics indicating that the objects named in the title of my talk are either non-existing or very elusive to detect (not a single such object is known against 119 known Be/neutron star X-ray ... -
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 ... -

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 ... -
