Abstract

A search for point-like sources of cosmic neutrinos has been performed using the 2007 to 2012 data collected by the ANTARES neutrino telescope. The search is performed by looking for accumulations of muon neutrinos over the expected atmospheric background. No clear signal has been found. The cluster of events with the highest significance (2.2σ) was found at equatorial coordinates (RA, DEC) = (-46.8°, -64.9°). Furthermore, 90% confidence level upper-limits have been set for 50 pre-selected astrophysical neutrino source candidates for an E-2 flux normalization. In addition, due to the accumulation of 7 high energy neutrinos close to the Galactic Centre recently reported by the IceCube collaboration, a specific search around 20° from the Galactic Centre has been performed. No evidence of a signal has been found in the ANTARES data within this region.
