Searches for Point Sources of High Energy Cosmic Neutrino with the ANTARES Telescope Dornic D. ∗ on behalf of the ANTARES Collaboration

The ANTARES observatory is currently the largest neutrino telescope in the Northern Hemi-sphere. It is well suited to detect high energy neutrinos produced in astrophysical sources as it can observe a full hemisphere of the sky at all the times with a high duty cycle and an angular resolution about 0.4 degrees. Due to its location in the South of France, ANTARES is sensitive to up-going neutrinos from many potential galactic sources in the TeV to PeV energy regime. Results from a time-integrated unbinned method as well as the sensitivity of the detector using 2007-2010 data are presented. Moreover, using a time-dependent search for the transient sources, the background rejection and point-source sensitivity can be drastically improved by selecting a narrow time window around the assumed neutrino production period. The gamma-ray light curves of blazars measured by the LAT instrument on-board the Fermi satellite reveal important time variability information. A strong correlation between the gamma-ray and the neutrino fluxes is expected in a hadronic scenario. First results on the search for ten bright and variable Fermi sources with the 2008 ANTARES data are also presented
