The measurements of astrophysical neutrinos by the IceCube collaboration are consistent with an isotropic flux but also contain some indications of a North/South asymmetry which could hint a Galactic contribution. The ANTARES neutrino telescope has a direct view of the Galactic Center region and can provide complementary information on the neutrino flux from this region thanks to its excellent angular resolution both for tracks and showers.

A recent model of cosmic-ray transport in the Galactic Plane, KRAγ, is characterized by radially-dependent cosmic-ray transport properties. It is designed to reproduce Fermi-LAT γ-ray data, and is consistent with MILAGRO and HESS measurements of the Galactic Ridge.

The neutrino flux from the Galactic Center predicted by this model is about five times larger than the flux computed with previous models, and it is close to the ANTARES sensitivity.

with IceCube High-Energy Starting Events (HESE). This analysis, extended to the full

visible sky of ANTARES, uses a maximum likelihood ratio approach. All neutrino flavors yielding track or cascade events are observed. Each HESE direction is treated as potential transient neutrino source direction while the neutrino burst duration and the number of ANTARES signal events are obtained as those maximizing the likelihood. Before applying the method to the unblinded ANTARES dataset, its sensitivity and discovery potential are computed through dedicated pseudo-experiments. This study provides an effective way to acquire information on the possible origin of the IceCube astrophysical signal from transient sources.

4. Search for signal emission from AGN populations with the

ANTARES neutrino telescope.

Rodrigo G. Ruiz
We use a two point correlation analysis to look for inhomogeneities in the arrival directions of the high energy muon neutrino candidates detected by the ANTARES neutrino telescope. This approach is complementary to a point source likelihood-based search, which is mainly sensitive to one bright point like source and not to collective effects. We present the results of a search based on this two-point correlation method performed on ANTARES data, providing constraints on models of a population of Active Galactic Nuclei (AGN) too faint to be detected by the likelihood-based method.

6. Search for neutrino emission from the Fermi Bubbles with the ANTARES telescope
The Fermi Bubbles are giant lobe-shaped structures of γ-ray emission extending above and below the Galactic Center. A variety of both hadronic and leptonic models has been proposed to explain the emission, yet its origin remains unclear. Only in hadronic scenarios, the γ-ray flux is accompanied by an associated neutrino flux that might be detected with large volume neutrino detectors.

ANTARES is the largest neutrino telescope in the Northern Hemisphere and has been operated in its final configuration since 2008. Its location in the Mediterranean sea provides an excellent view towards the Fermi Bubbles’ region.

The ANTARES detector is the largest and longest operated neutrino telescope in the Northern Hemisphere. All-flavour neutrino interactions can be observed and reconstructed with high precision by the experiment. The track channel – CC muon neutrino induced events – allows to increase the effective detector volume by the long path travelled by muons in rock and sea-water, with excellent angular resolution but limited energy reconstruction precision. The shower channel – all neutrino flavours NC and e, CC interactions– allows to reach a much better energy resolution, though it can be used only for events within a limited fiducial volume. The highly significant cosmic neutrino excess observed by the Antarctic IceCube detector can be studied with ANTARES exploiting the complementarity of its field of view and its reconstruction performance. Searches for all-sky diffuse neutrino signals have been conducted using the available ANTARES data set. The results of these searches will be reported in this contribution.

ANTARES is currently the largest neutrino telescope operating in the Northern Hemisphere, aiming at the detection of high-energy neutrinos from astrophysical sources. Such observations would provide important clues about the processes at work in those objects sources, and possibly help to understand the sources origin of very high-energy cosmic rays. By design, neutrino telescopes constantly monitor at least one complete hemisphere of the sky and are thus well set to detect neutrinos produced in transient astrophysical events sources. The flux of high-energy neutrinos from transient sources is expected to be lower than the one expected from steady ones sources, but the background originating from interactions of charged cosmic rays in the Earth’s atmosphere can be drastically reduced by requiring a directional and temporal coincidence of the astrophysical phenomenon detected by a satellite. Time-dependent point-source searches have been applied to a list of x-ray and gamma-ray binary systems detected by satellites such as Swift, Fermi or IACT using eight years of ANTARES data. The results of these searches are presented together with the comparison between the neutrino (?)flux upper-limits with the measured gamma-ray spectral energy distribution and the prediction from astrophysical models.

The ANTARES telescope is well suited for detecting astrophysical transient neutrino sources as it can observe a full hemisphere of the sky at all times with a high duty cycle. The background due to atmospheric particles can be drastically reduced, and the point-source sensitivity improved, by selecting a narrow time window around possible neutrino production periods. Blazars, being radio-loud active galactic nuclei with their jets pointing almost directly towards the observer, are particularly attractive potential neutrino point sources, since they are among the most likely sources of the very high-energy cosmic rays. Neutrinos and gamma rays may be produced in hadronic interactions with the surrounding medium. Moreover, blazars generally show high time variability in their light curves at different wavelengths and on various time scales.

A time-dependent analysis has been applied to a selection of flaring gamma-ray blazars observed by the FERMI/LAT experiment and by TeV Imaging Cherenkov telescopes using eight years of ANTARES data taken from 2008 to 2015. The results of these searches are presented together with the comparison between the neutrino ��flux upper-limits with the measured gamma-ray spectral energy distribution and the prediction from astrophysical models.
12. Search for a high-energy neutrino signal from Fast Radio Bursts with the ANTARES neutrino telescope
Turpin D., Dornic D. on behalf the ANTARES Collaboration

Fast Radio Bursts (FRBs) are one of the most intriguing transient radio sources discovered for the first time a decade ago. They are characterized by an intense radio pulse pulse of radio light (few Jy) lasting few milliseconds and mainly detected in the GHz energy band. Up to now, many unknowns remain concerning the nature of the transient progenitor, the nature of the radio emission and their distribution in the Universe. Recently, the first evidence on the association between the repeating burst FRB121102 and a star-forming dwarf galaxy located at the cosmological distance z = 0.19 was reported. These observations imply that at least some of the FRBs indeed originate from the distant Universe and have to be associated with extremely violent events to explain their observed brightness. So far, the radiative processes powering the radio emission are unknown but efficient particle acceleration may occur in the vicinity of the progenitor. A multi-wavelength and a multi-messenger approach are therefore crucial to identify the nature of these acceleration mechanisms. In this context, a search for a high-energy neutrino signal from the most recent radio bursts has been performed with the ANTARES neutrino telescope. By design, ANTARES mainly observes the Southern sky (2π steradian at any time) and is perfectly suited to search for a neutrino signal from transients that have been mainly detected at the Parkes observatory in Australia. In this contribution, we will present the results of our neutrino searches using the ANTARES detector and their implications for hadronic emission in such bursts.

High-energy neutrinos could be produced in the interaction of charged cosmic rays with matter or radiation surrounding astrophysical sources. Transient phenomena, such as gamma-ray bursts, core-collapse supernovae or active galactic nuclei are promising candidates to emit high-energy neutrinos. To search for coincidences between a transient event and a neutrino emission, a follow-up program of neutrino alerts has operated within the ANTARES Collaboration since 2009. This program triggers a network of robotic optical telescopes immediately after the detection of a neutrino event and schedule several observations in the following weeks. The most interesting neutrino candidates are also followed by the Swift XRT telescope and the Murchison Widefield Array (MWA) radio telescope and the H.E.S.S. high-energy gamma-ray telescope. By combining the information provided by the ANTARES neutrino telescope with information coming from other observatories, the probability of detecting a source is enhanced, allowing the possibility of identifying a neutrino progenitor from a single detected event. No optical counterpart associated with a neutrino emission has been identified during image analysis

To evaluate the significance of any correlation we used Monte Carlo simulations of randomly generated UHECR directions and comparing with data.

15. Multi-messenger real-time analyses of transient events with the ANTARES

neutrino telescope
By constantly monitoring at least one complete hemisphere of the sky, neutrino telescopes are well designed to detect neutrinos emitted by transient astrophysical events. Real-time searches for ANTARES neutrino candidates coincident with gamma-ray bursts, High-Energy Starting Events and Extremely High-Energy Events detected by

IceCube and gravitational wave (GW) candidates observed by LIGO/Virgo are performed. By requiring coincident detection, this approach increases the sensitivity of the telescope and the significance of a potential discovery. The latest results of these analyses will be presented. In particular, a neutrino follow-up is performed after the detection of GW events by the LIGO/Virgo collaboration. Since no coincident ANTARES event has been detected, the neutrino fluence and the total energy emitted in neutrinos

are constrained for each GW alert. Because of the better angular accuracy of neutrino telescopes compared to current GW detectors with two interferometers, a coincident detection would drastically constrain the position of the GW source on the sky, bringing valuable information for subsequent electromagnetic follow-ups.

18. New results from the search Indirect searches for dark matter with the ANTARES neutrino telescope

One of the mayor purposes of the ANTARES neutrino telescope is the indirect search for dark matter. The ANTARES detector is located on the bottom of the Mediterranean Sea 40 km off the southern French coast. and has been taking data since 2007. In this talk the results of the search for dark matter signals from the Sun, the Galactic Center and the Earth core and other celestial objects, produced with different analysis methods, will be presented. There are various advantages in indirect searches with neutrino telescopes and the limits presented for the Galactic Center in particular are the most stringent of all indirect detection experiments for WIMP masses above 30 TeV. (Comment on the spin-dependent from the Sun? From the Earth?)

19. ANTARES/IceCube combined search for DM ? Not found

20. Cosmic background from the Sun (Title??
Neutrino telescopes have been proposed as good tools for indirect detection of dark matter searches, especially using the Sun as source for its good capability to capture dark matter and since we do not expect high-energy neutrinos from it. However, the last statement should be taken with caution because high-energy neutrinos may come from cosmic particles interacting in the atmosphere of the Sun and producing neutrinos. In this work, we describe an analysis of the ANTARES neutrino telescope optimised for the observation of neutrinos coming from the atmosphere of the Sun due to cosmic particles interactions. Focusing in the 100 GeV - 10 TeV region and using 2007-2012 data, the sensitivity obtained is approximately 10 10 km2 y-1, whereas the flux expected is two order of magnitudes below. From this, we can conclude that present high-energy neutrino telescopes dark matter searches in the Sun can effectively neglect this contribution, but could play a role in future detectors with better neutrino flux sensitivities in the 10 GeV- 10 TeV region and very good angular resolution.
21. Update of the Search for ��≥0.6 magnetic monopoles search with the ANTARES neutrino telescope

New results on The search for magnetic monopoles with the ANTARES neutrino telescope are presented. These hypothetical particles carry only a magnetic charge. They would be created in the primordial Universe within the phase transition corresponding to the spontaneous breaking of the unified gauge group into subgroups, then would be accelerated by the Galactic magnetic fields and reach the Earth. Magnetic monopoles could be detected as highly ionizing particles in neutrino telescopes. This new analysis uses a total live time of 1121 days of the ANTARES detector. No signal above the background expectation from atmospheric muons and neutrinos is observed, and new 90% C.L. upper limits are set on the magnetic monopole flux in the range of velocities ��=���� ≥0.6 and masses (mass range from the paper)….

22. Nuclearites search with the ANTARES detector

Strange quark matter (SQM), consisting of roughly equal quantities of u, d and s quarks, was suggested to be the ground state of hadronic matter. SQM could be stable for baryon numbers A ranging from a few (ordinary nuclei) to 1057 (neutron stars). Lumps of SQM may have survived as relics of the Big Bang or as debris of supernovae and may contribute to the cold dark matter content in the Universe. Massive lumps of SQM, named nuclearites, may be present in the cosmic radiation and reach the Earth with non-relativistic velocities (��~10-3 ). Nuclearites moving slowly through water would produce a thermal shock wave, emitting blackbody radiation and yielding a large amount of visible light. The ANTARES neutrino telescope, currently operating in the Mediterranean Sea, is sensitive to the signal of nuclearites (��! ≳ 10^14 GeV). New results on the search for downgoing nuclearites with ANTARES will be presented, using an extended data set.
