The year 2017 brought important breakthroughs to the astro-particle community, the first
detection of an electromagnetic counterpart of the gravitational wave signal from a binary
neutron star merger and the potential correlation between high-energy neutrinos observed by the
IceCube telescope and the flaring blazar TXS 0506+056. These observations have opened a new
way to probe extreme phenomena in the sky. Combination of these messengers is now possible
and fundamental information can be obtained with these new probes.
The ANTARES neutrino telescope has been operating for more than ten years in the Mediter-
ranean sea with the purpose of searching for high energy cosmic neutrinos. During the last few
years the multi-messenger approach has delivered intriguing new results for Cherenkov neutrino
detectors with promising potential for future astrophysical searches. Thus, the ANTARES Col-
laboration is actively participating to the follow up of alerts sent by different experiments cover-
ing the full electromagnetic spectrum, IceCube and the gravitational-wave interferometers. This
allows probe the potential neutrino emission from various sources, including fast radio bursts,
gamma-ray bursts, binary mergers and blazars. ANTARES also sends alerts that lead to an elec-
tromagnetic follow-up of interesting neutrino events. The latest results will be discussed in the
