THE FIRST STARS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Pop III stars are the key to the character of primeval galaxies, the first heavy elements, the onset of cosmological reionization, and the seeds of supermassive black holes. Unfortunately, in spite of their increasing ... -
THE GERDA EXPERIMENT: STATUS AND FUTURE PLANS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The GERDA experiment is searching for the neutrinoless double beta decay of 76Ge. An observation of the neutrinoless double beta decay will not only prove lepton number violation by two units, but also that the neutrino ... -
THE HISTORY OF THE S PROCESS AND ITS PRESENT STATE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We review the history and the present status of the s-process and point to problems in need of clarification. In some cases it has to do with lack of experimental data and in other the theory is missing. -
THE IMPACT OF SUZAKU MEASUREMENTS ON ASTROPARTICLE PHYSICS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Results from the Suzaku X-ray broad-band observations of clusters of galaxies are summarized. Aiming at understanding the physics of gas heating/particle acceleration and the cluster dynamical evolution, we search for ... -
THE JEM-EUSO MISSION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The JEM-EUSO mission explores the origin of the extreme energy cosmic rays (EECRs) above 50EeV and explores the limits of the fundamental physics, through the observations of their arrival directions and energies. It is ... -
THE MASS COMPOSITION OF ULTRA HIGH ENERGY COSMIC RAYS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The status of the Mass Composition measurements of Ultra High Energy Cosmic Rays is presented, with emphasis on the results from the Fluorescence Detector of the Pierre Auger Observatory. Possible consequences of the present ... -
THE NA62 EXPERIMENT AT CERN AND THE MEASUREMENT OF THE ULTRA-RARE DECAY K⁺→π⁺ v ̄v
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The NA62 experiment at CERN aims at the very challenging task of measuring with 10% relative error the Branching Ratio of the ultra-rare decay of the K+ into π+ ν¯ν which is expected to occur only in about 8 out of 1011 ... -
THE PAST AND THE FUTURE OF DIRECT SEARCH OF GW FROM PULSARS IN THE ERA OF GW ANTENNAS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)In this paper we will give an overview of the past and present status of Gravitational Wave (GW) research associated with pulsars, taking into account the target sensitivity achieved from interferometric laser GW antennas ... -
THE SEARCH FOR BLAZARS AMONG THE UNIDENTIFIED EGRET gamma-RAY SOURCES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)In this paper we report the results of a multi-wavelength follow-up study of selected flat spectrum extragalactic radio-optical counterparts within the error boxes of 13 unidentified EGRET sources. Two of these previously ... -
THE SENSITIVITY OF THE GREENHOUSE EFFECT TO CHANGES IN THE CONCENTRATION OF GASES IN PLANETARY ATMOSPHERES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We present a radiative transfer model for Earth-Like-Planets (ELP). The model allows the assessment of the effect of a change in the concentration of an atmospheric component, especially a greenhouse gas (GHG), on the ... -
THE SZ EFFECT IN THE PLANCK ERA: ASTROPHYSICAL AND COSMOLOGICAL IMPACT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The Sunyaev–Zel’dovich effect (SZE) is a relevant probe for cosmology and particle astrophysics. The Planck Era marks a definite step forward in the use of this probe for astrophysics and cosmology. Astrophysical applications ... -
THERMAL AND CHEMICAL EVOLUTIONS OF GALAXY CLUSTERS OBSERVED WITH SUZAKU
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We studied the properties of the intracluster medium (ICM) of galaxy clusters to outer regions observed with Suzaku. The observed temperature dropped by about ~30% from the central region to the virial radius of the clusters. ... -
ULTRAHIGH ENERGY COSMIC RAYS: REVIEW OF THE CURRENT SITUATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We describe the current situation of the data on the highest energy particles in the Universe – the ultrahigh energy cosmic rays. The new results in the field come from the Telescope Array experiment in Utah, U.S.A. For ... -
WHAT IS NEW IN ASTROPARTICLE PHYSICS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)In this brief review paper I will point to the most important steps that have been made in recent decades toward a better understanding of the physics governing our Universe. Because of the limited length of this paper, I ... -
XMM-NEWTON SCIENTIFIC HIGHLIGHTS: X-RAY SPECTROSCOPIC POPULATION STUDIES OF AGN
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)In this paper I review the contribution that the XMM-Newton ESA X-ray mission has given to our understanding of Active Galactic Nuclei, together with other operational, and complementary, X-ray facilities. I will focus on ...
