“…The discovery potential of such experiments strongly depends on the mass of the WIMP, its preferred annihilation channel and the thermally averaged annihilation cross section times velocity in the Earth today. A promising candidate for an improved future search is Km3Net [30] with the ORCA extension [31].…”

The ANTARES neutrino telescope is a water Cherenkov detector and currently the largest operating neutrino telescope in the Northern Hemisphere. One of the main scientific goals of ANTARES is the indirect search for dark matter, as the Weakly Interacting Massive Particle (WIMP). WIMPs could scatter on normal matter and therefore be gravitational bound in massive astronomical objects like the Earth. Therefore an indirect search for dark matter can be performed by looking for an excess of the neutrino flux from the Earth's core. The exact spectrum of the neutrino flux from the Earth would depend on the WIMP mass, the annihilation channel, the spin independent scattering cross section and the thermally averaged annihilation cross section of the WIMPs. Such a search has been done with the data taken by ANTARES from 2007 to 2012. First limits from this search will be presented.

“…Of particular relevance to blazar research will be, in the author's opinion, the Cherenkov Telescope Array [CTA 12] and the Imaging X-ray Polarimetry Explorer [IXPE,186], while ground-based radio and optical flux and polarimetry monitoring projects will continue, and hopefully the Fermi Gamma-Ray Space Telescope and the Neil Gehrels Swift X-Ray Observatory will continue to provide all-sky GeV γ-ray monitoring and flexible X-ray coverage to blazar observations, respectively, for several years to come. KM3NeT [16,129] and planned upgrades to IceCube [IceCube- Gen2 4,35] and the Lake Baikal neutrino detector [29] will greatly improve our view of the neutrino sky and hopefully provide a definitive answer whether blazars are PeV neutrino sources. If selected, also future missions such as the All-sky Medium Energy Gamma-ray Observatory [AMEGO,136] would provide a boost to the study of blazars.…”

Progress in Multi-Wavelength and Multi-Messenger Observations of Blazars and Theoretical Challenges

This review provides an overview of recent advances in multi-wavelength and multi-messenger observations of blazars, the current status of theoretical models for blazar emission, and prospects for future facilities. The discussion of observational results will focus on advances made possible through the Fermi Gamma-Ray Space Telescope and ground-based gamma-ray observatories (H.E.S.S., MAGIC, VERITAS), as well as the recent first evidence for a blazar being a source of IceCube neutrinos. The main focus of this review will be the discussion of our current theoretical understanding of blazar multi-wavelength and multi-messenger emission, in the spectral, time, and polarization domains. Future progress will be expected in particular through the development of the first X-ray polarimeter, IXPE, and the installation of the Cherenkov Telescope Array (CTA), both expected to become operational in the early to mid 2020s.

Context. The origin of the high-energy flux of neutrinos detected by IceCube is still unknown. Recent works report the evidence for a possible positional correlation between the reconstructed neutrino arrival directions and the positions in the sky of low power, high-energy emitting BL Lac objects (HBL). Aims. Assuming that γ-ray emitting HBL form the bulk of the sources of high-energy neutrinos above 100 TeV, we intend to calculate the number of events expected to be detected for each source by IceCube and KM3NeT. Methods. Based on a simple theoretically-motivated framework inspired by the structured jet scenario for these sources, we postulate a direct proportionality between high-energy γ-ray and neutrino fluxes. We calculate the expected neutrino event rate for the HBL sources of the Second Fermi-LAT Catalog of High-Energy Sources (2FHL) for IceCube and the presently under construction KM3NeT using declination-dependent and exposure-weighted effective areas. Results. We provide a list of 2FHL HBL with the calculated number of events. For IceCube, the derived count rate for several sources is relatively high, of the order of 1 yr −1 , consistently with the recent findings of a possible positional correlation. For KM3NeT the calculated rates are higher, with several sources with expected rate exceeding 1 yr −1 . This, coupled with the improved angular resolution, implies that the HBL origin can be effectively tested with few years of observation of KM3NeT (and IceCube Gen2, for which similar performances are foreseen) through the direct association of neutrinos and single HBL. Conclusions. Our results show that if -as hinted by recent works -HBL represent a possible population of high-energy neutrino emitters, several single sources should be identified in few years of exposure of KM3NeT, highlighting the importance of the improved angular resolution anticipated for KM3NeT and IceCube Gen2.
