A novel method for the absolute fluorescence yield measurement by AIRFLY
AIRFLY Collaboration, M. Ave
One of the goals of the AIRFLY (AIR FLuorescence Yield) experiment is to measure the absolute fluorescence yield induced by electrons in air to better than 10% precision. We introd…
Improved analysis of SN1987A antineutrino events
G. Pagliaroli, F. Vissani, M. L. Costantini +1
We propose a new parameterization of the antineutrino flux from core collapse supernovae, that allows an interpretation of its astrophysical parameters within the Bethe and Wilson…
Features of Kamiokande-II, IMB and Baksan observations and their interpretation in a two-component model for the signal
Giulia Pagliaroli, Francesco Vissani
We consider the time, angular and energy distributions of SN1987A events discussing the quality of their agreement with the expectations. A global interpretation is performed consi…
How precisely neutrino emission from supernova remnants can be constrained by gamma ray observations?
F. L. Villante, F. Vissani
We propose a conceptually and computationally simple method to evaluate the neutrinos emitted by supernova remnants using the observed gamma-ray spectrum. The proposed method does…
Observation of the suppression of the flux of cosmic rays above 4x10^19eV
The Pierre Auger Collaboration
The energy spectrum of cosmic rays above 2.5x10^18eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the flux, J ~ E…
Detection of GRB signals with Fluorescence Detectors
R. Aloisio, D. Boncioli, A. F. Grillo +5
Gamma Ray Bursts are being searched in many ground based experiments detecting the high energy component (GeV TeV energy range) of the photon bursts. In this paper, Fluorescenc…
Discovery of underground argon with low level of radioactive 39Ar and possible applications to WIMP dark matter detectors
C. Galbiati, R. Purtschert
We report on the first measurement of 39Ar in argon from underground natural gas reservoirs. The gas stored in the US National Helium Reserve was found to contain a low level of 39…
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
The Pierre Auger Collaboration
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…
Upper limit on the diffuse flux of UHE tau neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration
The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau-neutrinos that interact in the Earth's crust. Tau leptons from charged-cur…
Temperature and Humidity Dependence of Air Fluorescence Yield measured by AIRFLY
M. Ave
The fluorescence detection of ultra high energy cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules over a wide range of atmospheri…
Super Heavy Dark Matter and UHECR Anisotropy at Low Energy
R. Aloisio, F. Tortorici
Super Heavy quasi-stable particles are naturally produced in the early universe and could represent a substantial fraction of the Dark Matter: the so-called Super Heavy Dark Matter…
Measurement of the pressure dependence of air fluorescence emission induced by electrons
AIRFLY Collaboration
The fluorescence detection of ultra high energy (> 10^18 eV) cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules, which are excited…
Observation of inertial energy cascade in interplanetary space plasma
Luca Sorriso-Valvo, Raffaele Marino, Vincenzo Carbone +6
We show in this article direct evidence for the presence of an inertial energy cascade, the most characteristic signature of hydromagnetic turbulence (MHD), in the solar wind as ob…
First results from a Dark Matter search with liquid Argon at 87 K in the Gran Sasso Underground Laboratory
P. Benetti, R. Acciarri, F. Adamo +29
A new method of searching for dark matter in the form of weakly interacting massive particles (WIMP) has been developed with the direct detection of the low energy nuclear recoils…
The Lidar System of the Pierre Auger Observatory
S. Y. BenZvi, R. Cester, M. Chiosso +27
The Pierre Auger Observatory in Malargue, Argentina, is designed to study the origin of ultrahigh energy cosmic rays with energies above 10^18 eV. The energy calibration of the det…
Is there a problem with low energy SN1987A neutrinos?
Maria Laura Costantini, Aldo Ianni, Giulia Pagliaroli +1
(abridged) We study the low energy events observed by Kamiokande-II. We focus on the event 6 of 6.3 MeV and also on the other events that at 1 sigma fall below the energy threshold…
Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory
The Pierre Auger Collaboration
Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this…
An upper limit to the photon fraction in cosmic rays above 10^19 eV from the Pierre Auger Observatory
Pierre Auger Collaboration
An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies greater than 10^19 eV, based on observations of the depth of shower maximum perf…
Measurement of the specific activity of Ar-39 in natural argon
P. Benetti, F. Calaprice, E. Calligarich +21
We report on the measurement of the specific activity of Ar-39 in natural argon. The measurement was performed with a 2.3-liter two-phase (liquid and gas) argon drift chamber. The…
Neutrinos from Supernovas and Supernova Remnants
Francesco Vissani, Maria Laura Costantini
Supernovae (SN) and supernova remnants (SNR) have key roles in galaxies, but their physical descriptions is still incomplete. Thus, it is of interest to study neutrino radiation to…
Evolutionary and structural properties of mirror star MACHOs
Zurab Berezhiani, Paolo Ciarcelluti, Santi Cassisi +1
There can exist a hidden sector of the Universe in the form of parallel ''mirror'' world which has the same particle physics as the observable world and interacts with the latter o…
