    Performance of the ICARUS T600 detector
  2. 342
    “…Many possible explanations have been suggested, invoking one or more nearby primary sources such as pulsars and supernova remnants, or dark matter. Based on the output of the TANGO in PARIS --Testing Astroparticle with the New GeV/TeV Observations in Positrons And electRons : Identifying the Sources-- workshop held in Paris in May 2009, we review here the latest experimental results and we discuss some virtues and drawbacks of the many theoretical interpretations proposed so far.…”

    por De Angelis, Alessandro
    Publicado 2012
    “…Grazie ad avventurosi studi fu possibile dimostrare un secolo fa che parte della radiazione naturale che si osserva sulla Terra è di natura extraterrestre: era la scoperta dei cosiddetti “raggi cosmici”, particelle che arrivano da misteriosi acceleratori nell’universo, probabilmente buchi neri supermassicci e resti di supernova, a energie anche centinaia di milioni di volte di quelle a cui riusciamo a produrle con i più potenti acceleratori della Terra. …”

    Publicado 2015
    “…I will show that within the same model one can explain the excess of positrons and antiprotons above 20 GeV found by PAMELA and AMS-02, the discrepancy in the slopes of the spectra of cosmic ray protons and heavier nuclei in the TeV-PeV energy range and the plateau in cosmic ray dipole anisotropy in the 2-50 TeV energy range by adding the effects of a 2 million year old nearby supernova.…”

    “…We report on the operation of the resonant gravitational wave (GW) detector EXPLORER of the Rome group (M=2300 kg, T=2.6 K, located at CERN) at the time of the gamma-ray burst GRB 980425 (April 25.90915 UT, 1998), which is probably associated with the supernova SN 1998bw. We present the data of the detector (with sensitivity h/sub c/=8*10 /sup -19/ for a 1 ms pulse), and use the BeppoSAX data to estimate the initial time of the GRB: a basic parameter for any correlation analysis. …”
