Supernova Neutrino Detection
Astronomers expect that every 30 years or so, a massive star in our Galaxy will reach the end of its life. When the core of such a star collapses, it emits nearly all of the gravitational binding energy of a neutron star in the form of neutrinos, some Eb ∼ 3 × 10 53 ergs. Less than 1% of this energy is released in the form of kinetic energy and optically visible radiation. The remainder is radi...
متن کاملDetection of Supernova Neutrinos * * *
Matter effects on neutrino oscillations in both, a supernova and the Earth, change the observed supernova neutrino spectra. We calculate the expected number of supernova neutrino interactions for ICARUS, SK and SNO detectors as a function of the distance which they traveled in the Earth. Calculations are performed for supernova type II at 10 kpc from the Earth, using standard supernova neutrino...
متن کاملSupernova Neutrino Detection in Borexino
We calculated the expected neutrino signal in Borexino from a typical Type II supernova at a distance of 10 kpc. A burst of around 110 events would appear in Borexino within a time interval of about 10 s. Most of these events would come from the reaction channel ν̄e + p → e+ + n, while about 30 events would be induced by the interaction of the supernova neutrino flux on 12C in the liquid scintil...
متن کاملTHE EXTREMELY LUMINOUS SUPERNOVA 2006gy AT LATE PHASE: DETECTION OF OPTICAL EMISSION FROM SUPERNOVA
Supernova (SN) 2006gy is an extremely luminous Type IIn SN characterized by the bright peak magnitude MR ∼ −22 mag and its long duration. The mechanism giving rise to its huge luminosity is still unclear. We performed optical spectroscopy and photometry of SN 2006gy at late time, ∼ 400 days after the explosion, with the Subaru/FOCAS in a good seeing condition. We carefully extracted the SN comp...
متن کاملDetection of the characteristic pion-decay signature in supernova remnants.
Cosmic rays are particles (mostly protons) accelerated to relativistic speeds. Despite wide agreement that supernova remnants (SNRs) are the sources of galactic cosmic rays, unequivocal evidence for the acceleration of protons in these objects is still lacking. When accelerated protons encounter interstellar material, they produce neutral pions, which in turn decay into gamma rays. This offers ...
