Observations of neutral-current ν interactions on deuterium in the Sudbury Neutrino
Observatory are reported. Using the neutral current (NC), elastic scattering, and charged current …

The discovery of afterglows associated with γ-ray bursts at X-ray 1 , optical 2 and radio 3
wavelengths and the measurement of the redshifts of some of these events 4 , 5 has …

The Sudbury Neutrino Observatory (SNO) has measured day and night solar neutrino energy
spectra and rates. For charged current events, assuming an undistorted 8 B spectrum, the …

For almost a quarter of a century 1 , the origin of γ-ray bursts— brief, energetic bursts of high-energy
photons—has remained unknown. The detection of a counterpart at another …

The Sudbury Neutrino Observatory has precisely determined the total active (ν x) B 8 solar
neutrino flux without assumptions about the energy dependence of the ν e survival probability…

Establishing the nature of γ-ray bursts is one of the greatest challenges in high-energy
astrophysics. The distribution of these bursts is isotropic across the sky, but inhomogeneous in …

We present the main results of a study of spectral and energetics properties of twelve
gamma-ray bursts (GRBs) with redshift estimates. All GRBs in our sample were detected by …

The origin of γ-ray bursts (GRBs) has been enigmatic since their discovery 1 . The situation
improved dramatically in 1997, when the rapid availability of precise coordinates 2 , 3 for the …

The Sudbury Neutrino Observatory is a second-generation water Cherenkov detector designed
to determine whether the currently observed solar neutrino deficit is a result of neutrino …

The first sensors of the IceCube neutrino observatory were deployed at the South Pole during
the austral summer of 2004–2005 and have been producing data since February 2005. …
