| Abstract: | A search for point-like and extended sources of cosmic neutrinos using data
collected by the ANTARES and IceCube neutrino telescopes is presented. The data
set consists of all the track-like and shower-like events pointing in the
direction of the Southern Sky included in the nine-year ANTARES point-source
analysis, combined with the through-going track-like events used in the
seven-year IceCube point-source search. The advantageous field of view of
ANTARES and the large size of IceCube are exploited to improve the sensitivity
in the Southern Sky by a factor $sim$2 compared to both individual analyses.
In this work, the Southern Sky is scanned for possible excesses of spatial
clustering, and the positions of preselected candidate sources are
investigated. In addition, special focus is given to the region around the
Galactic Centre, whereby a dedicated search at the location of SgrA* is
performed, and to the location of the supernova remnant RXJ 1713.7-3946. No
significant evidence for cosmic neutrino sources is found and upper limits on
the flux from the various searches are presented. |
