RECENT DEVELOPMENTS IN ULTRA-HIGH ENERGY NEUTRINO ASTRONOMY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We outline the current situation in ultrahigh energy (UHE) cosmic ray physics, pointing out the remaining problems, in particular the puzzle concerning the origin of the primary radiation and the role of neutrino astronomy ...
LIMIT ON UHE NEUTRINO FLUXES FROM THE PIERRE AUGER OBSERVATORY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The surface detector of the Pierre Auger Observatory is sensitive to Ultra High Energy (UHE) neutrinos. Neutrinos of all flavors can interact in the atmosphere producing inclined showers near the ground. Moreover, ultra ...
SEARCH FOR GRAVITATIONAL WAVES FROM SUPERNOVAE AND LONG GRBS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We report on evidence for black hole spindown in the light curves of the BATSE catalogue of 1491 long GRBs by application of matched filtering. This observation points to a strong interaction of the black hole with surrounding ...
NEUTRINOS FROM ICARUS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Liquid Argon Time Projection Chambers are very promising detectors for neutrino and astroparticle physics due to their high granularity, good energy resolution and 3D imaging, allowing for a precise event reconstruction. ...
ANALYSIS OF THE MACRO EXPERIMENT DATA TO COMPARE PARTICLE ARRIVAL TIMES UNDER GRAN SASSO
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The claim of a neutrino velocity different from the speed of the light, made in September 2011 by the Opera experiment, suggested the study of the time delays between TeV underground muons in the Gran Sasso laboratory using ...
ICECUBE OBSERVATORY: NEUTRINOS AND THE ORIGIN OF COSMIC RAYS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The completed IceCube Observatory, the first km3 neutrino telescope, is already providing the most stringent limits on the flux of high energy cosmic neutrinos from point-like and diffuse galactic and extra-galactic sources. ...
FROM GALACTIC TO EXTRAGALACTIC JETS: A REVIEW
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
An analysis of the data that have recently become available from observing campaigns, including VLA, VLBA, and satellite instruments, shows some remarkable similarities and significant differences in the data from some ...
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 ...
AGILE DATA CENTER AT ASDC AND AGILE HIGHLIGHTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We present an overview of the main AGILE Data Center activities and the AGILE scientific highlights during the first 5 years of operations. AGILE is an ASI space mission in joint collaboration with INAF, INFN and CIFS, ...
MODELING JET INTERACTIONS WITH THE AMBIENT MEDIUM
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Recent high-resolution (see, e.g., [13]) observations of astrophysical jets reveal complex structures apparently caused by ejecta from the central engine as the ejecta interact with the surrounding interstellar material. ...
