Multi-Messenger Studies with AMANDA/IceCube: Observations and Strategies

Four years of AMANDA-II data have been searched for neutrinos from point sources. No statistically significant excess of events has been detected, neither integrated in the years 2000 to 2003, nor in the searches for occasional signals. An…

The 2019 Taurid resonant swarm: prospects for ground detection of small NEOs

In June 2019 the Earth will approach within 5{\deg} mean anomaly of the centre of the Taurid resonant swarm, its closest post-perihelion encounter with Earth since 1975. This will be the best viewing geometry to detect and place limits on…

Follow-up observations of binary ultra-cool dwarfs

Astrometric observations of resolved binaries provide estimates of orbital periods and will eventually lead to measurement of dynamical masses. Only a few very low mass star and brown dwarf masses have been measured to date, and the…

Now the Dark Electron Multiplier does sense direction of the daemon motion

Detection of the September maximum in the primary near-Earth daemon flux at high (~60o) Northern latitudes by our set-up with a plane horizontal scintillator is plagued by purely geometric factors; indeed, because of the Earth's rotation…
