A search for cosmic neutrino sources using the data collected with the ANTARES neutrino telescope between early 2007 and the end of 2015 is performed. For the first time, all neutrino interactions—charged- and neutral-current interactions of all flavors—are considered in a search for point-like sources with the ANTARES detector. In previous analyses, only muon neutrino charged-current interactions were used. This is achieved by using a novel reconstruction algorithm for shower-like events in addition to the standard muon track reconstruction. The shower channel contributes about 23% of all signal events for an E−2 energy spectrum. No significant excess over background is found. The most signal-like cluster of events is located at (α,δ)=(343.8°,23.5°) with a significance of 1.9σ. The neutrino flux sensitivity of the search is about E2dΦ/dE=6×10−9 GeV cm−2 s−1 for declinations from −90° up to −42°, and below 10−8 GeV cm−2 s−1 for declinations up to 5°. The directions of 106 source candidates and 13 muon track events from the IceCube high-energy sample events are investigated for a possible neutrino signal and upper limits on the signal flux are determined.

Energy efficiency is a primary design concern for embedded multiprocessor system-on-chips (MPSoCs). Recently, Voltage-Frequency Island (VFI) - based design paradigm was introduced for fine-grained power management, which can seamlessly combine with the task scheduling algorithm to optimize system energy. However, the ever-increasing variabilities cause large uncertainty on delay and power. Such statistical nature in performance parameters easily makes deterministic energy optimization hard to achieve desirable performance yield, defined as the probability of the design meeting timing constraints of the system. In this paper, we propose a variation-aware statistical energy optimization framework, which takes account of performance yield constraints in energy-aware task scheduling, voltage assignment and VFI partitioning process. Energy optimization sensitivity, defined as energy variations of the task under voltage scaling, combines with the statistical slack of the task to guide the overall optimization flow. Experimental results demonstrate the effectiveness of the proposed scheme.

Muons created by νµ charged current (CC) interactions in the water surrounding the ANTARES neutrino telescope have been almost exclusively used so far in searches for cosmic neutrino sources. Due to their long range, highly energetic muons inducing Cherenkov radiation in the water are reconstructed with dedicated algorithms that allow the determination of the parent neutrino direction with a median angular resolution of about 0.4◦ for an E−2 neutrino spectrum. In this paper, an algorithm optimised for accurate reconstruction of energy and direction of shower events in the ANTARES detector is presented. Hadronic showers of electrically charged particles are produced by the disintegration of the nucleus both in CC and neutral current (NC) interactions of neutrinos in water. In addition, electromagnetic showers result from the CC interactions of electron neutrinos while the decay of a tau lepton produced in ντ CC interactions will in most cases lead to either a hadronic or an electromagnetic shower. A shower can be approximated as a point source of photons. With the presented method, the shower position is reconstructed with a precision of about 1 m;the neutrino direction is reconstructed with a median angular resolution between 2◦ and 3◦ in the energy range of 1 TeV to 1000 TeV. In this energy interval, the uncertainty on the reconstructed neutrino energy is about 5 % to 10 %. The increase in the detector sensitivity due to the use of additional information from shower events in the searches for a cosmic neutrino flux is also presented. Copyright © 2017, The Authors.

Neutrino telescopes have been proposed as efficient tools for indirect 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 particle interactions 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 10 GeV - 10 TeV energy range and using 2007-2012 data, the sensitivity obtained for the flux is approximately 1012 km-2 y-1, whereas the expected flux is two order of magnitudes below. From this, we can conclude that present high-energy neutrino telescopes dark matter searches in the Sun can indeed neglect this contribution, but could play a role in future detectors with better neutrino flux sensitivities in the 10 GeV - 10 TeV energy range and very good angular resolution.

The principles of a search for high energy neutrino emission in coincidence with very high energy (VHE;0.1-100 TeV) gamma-ray flares from two bright extragalactic sources, based on the data collected in 2012-2016 by the ANTARES neutrino detector and High Altitude Water Cherenkov (HAWC) gamma-ray observatory, are presented. The ANTARES telescope observes with high duty cycle an instantaneous field of view of 2π. To study variable sources like blazars, it is crucial to achieve unbiased monitoring and an instrument like HAWC is capable of long term and continuous monitoring of the source with nearly 100% duty cycle. Markarian 421 (Mrk 421) and Markarian 501 (Mrk 501) are the brightest and the closest BL Lac objects known. In contrast to other types of active galactic nuclei (AGN), BL Lacs are characterized by rapid and large-amplitude flux variability. Such radio-loud AGNs with collimated jets aligned to the line of sight, are candidate sources of the observed high energy cosmic rays and of accompanying neutrinos and gamma rays produced in hadronic interactions with the surrounding medium.

Advanced LIGO detected a significant gravitational wave signal (GW170104) originating from the coalescence of two black holes during the second observation run on January 4th, 2017. An all-sky high-energy neutrino follow-up search has been made using data from the Antares neutrino telescope, including both upgoing and downgoing events in two separate analyses. No neutrino candidates were found within ±500 s around the GW event time nor any time clustering of events over an extended time window of ±3 months. The non-detection is used to constrain isotropic-equivalent high-energy neutrino emission from GW170104 to less than ∼ 4 × 1054 erg for a E−2 spectrum. Copyright © 2017, The Authors.
