Multifrequency Behaviour of the Gamma-Ray Binary System PSR B1259-63: Modelling the FERMI Flare
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)This paper presents a brief overview of the multifrequency properties of the gamma-ray binary system PSR B1259-63 from radio to very high energy gamma-rays. A summary is also presented of the various models put forward to ... -
Old and New from Multifrequency Astrophysics
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)In this short review paper we comment on some the most important steps that have been made in the past decades for a better understanding of the physics governing our Universe. The results we discuss come from the many ... -
LHC, Astrophysics and Cosmology
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)In this paper we discuss the impact on cosmology of recent results obtained by the LHC (Large Hadron Collider) experiments in the 2011-2012 runs, respectively at √s = 7 and 8 TeV. The capital achievement of LHC in this ... -
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 ... -
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 ... -
Latest Results from the Fermi Gamma-Ray Telescope
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Can we learn about New Physics with astronomical and astro-particle data? Since its launch in 2008, the Large Area Telescope, onboard of the Fermi Gamma-ray Space Telescope, has detected the largest amount of gamma rays ... -
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 ... -
Star Formation as Seen by Low Mass Stars
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Using the Hubble Space Telescope (HST) we have characterised and compared the physical properties of a large sample of pre-main sequence (PMS) stars spanning a wide range of masses (0:5 - 4Mʘ), metallicities (0:1 - 1 Zʘ) ... -
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 ... -
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 ... -
V2282 Sgr Revisited
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)The nature of V2282 Sgr is examined on the basis of several multiband observations: a 20 years long I-band light curve of V2282 Sgr obtained from archive photographic plates of the Asiago and Catania Observatories; a CCD ... -
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 ... -
The Formation of Massive Stars: from Herschel to Near-Infrared
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We have studied a number of selected high mass star forming regions, including high resolution near-infrared broad- and narrow-band imaging, Herschel (70, 160, 250, 350 and 500 μm) and Spitzer (3.6, 4.5, 5.8 and 8.0 m) ... -
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 ... -
