Thermal MeV neutrino emission from core-collapse supernovae offers a unique opportunity to probe physics beyond the Standard Model in the neutrino sector. The next generation of neutrino experiments, such as DUNE and Hyper-Kamiokande, can detect 𝒪(103) and 𝒪(104) neutrinos in the event of a Galactic supernova, respectively. As supernova neutrinos propagate to Earth, they may interact with the local dark matter via hidden mediators and may be delayed with respect to the initial neutrino signal. We show that for sub-MeV dark matter, the presence of dark matter-neutrino interactions may lead to neutrino echoes with significant time delays. The absence or presence of this feature in the light curve of MeV neutrinos from a supernova allows us to probe parameter space that has not been explored by dark matter direct detection experiments.

“…Initial ground thermal properties were set according to sediments types and ground ice contents measured from recovered permafrost samples. The differences between air temperatures and ground surface temperatures were determined by using n-factors (Lunardini, 1978;Burn and Smith, 1988). Measured freezing and thawing n-factor values had been previously obtained by recording air and surface temperatures over a year or two under various vegetation and snow covers in Nunavik (Ménard et al 1998;Allard et al 2004;L'Hérault et al, 2012;LeBlanc, 2013); they were applied at the thermistor cable sites after site visits made during summer to observe vegetation cover and in late winter to measure maximum snow depth.…”

Facing the challenge of permafrost thaw in Nunavik communities: innovative integrated methodology, lessons learnt, and recommendations to stakeholders

In order to support climate change adaptation in the communities of Nunavik, an innovative multi-technique approach to map permafrost conditions and assess risks of geohazards at the community-scale level was applied. Four maps were produced for each community: 1- a surficial geology map, 2- a map of permafrost conditions based on ground-ice content and depth to bedrock, 3- a map of potential for construction and 4- a geohazard risk assessment map. Local ground temperature data from thermistor cables were used to calibrate one-dimensional numerical models to estimate future permafrost temperature changes and probable rates of degradation in different environmental settings within the communities and under different climate change scenarios for the 2019-2100 period. Throughout this project, abundant consultations were held in communities and with stakeholders to better understand their concerns and to provide pragmatic recommendations for improving construction methods and land-use planning to face the challenges of permafrost thaw. Specific recommendations were made to the higher levels of government for improving construction practices. Inuit aspirations, culture and leadership remain keys in how to integrate permafrost geotechnical knowledge in planning a safe future for the communities.

Abstract. ANTARES is the largest neutrino telescope in the Northern hemisphere, running in its final configuration since 2008. After the discovery of a cosmic neutrino diffuse flux by the IceCube detector, the search for its origin has become a key mission in highenergy astrophysics. The ANTARES sensitivity is large enough to constrain the origin of the IceCube excess from regions extended up to 0.2 sr in the Southern sky. The Southern sky has been studied searching for point-like objects, for extended regions of emission (as the Galactic plane) and for signal from transient objects selected through multimessenger observations. Upper limits are presented assuming different spectral indexes for the energy spectrum of neutrino sources. In addition, ANTARES provides results on studies of the sky in combination with different multimessenger experiments, on atmospheric neutrinos, on the searches for rare particles in the cosmic radiation (such as magnetic monopoles and nuclearites), and on Earth and Sea science. Particularly relevant are the searches for Dark Matter: the limits obtained for the spin-dependent WIMP-nucleon cross section overcome that of existing direct-detection experiments. The recent results, widely discussed in dedicated presentations during the 7 th edition of the Very Large Volume Neutrino Telescope Workshop (VLVνT-2015), are highlighted in this paper.
