Cosmic rays arriving at Earth include the most energetic particles ever observed. The mechanism of their acceleration and sources are, however, still mostly unknown. Observing astrophysical neutrinos can help solve this problem. Because are produced in hadronic interactions neither absorbed nor deflected, they will point directly back to source. This contribution covers continued studies high-energy neutrino flux observed IceCube observatory, extending them from four six years data with a...

A multimessenger analysis optimized for a correlation of arrival directions ultra-high energy cosmic rays (UHECRs) and neutrinos is presented applied to 2190 neutrino candidate events detected in 2007–2008 by the ANTARES telescope 69 UHECRs observed Pierre Auger Observatory between 2004 January 1 2009 December 31. No significant observed. Assuming an equal flux (E−2 spectrum) from all UHECR directions, 90% CL upper limit on 5.0 × 10−8 GeV cm−2 s−1 per source derived.
The identification of the electromagnetic counterpart gravitational wave event, GW170817, and discovery neutrinos gamma-rays from TXS 0506+056 heralded new era multi-messenger astrophysics. As number events rapidly grow over next decade, cyberinfrastructure requirements to handle increase in data rates, volume, need for event follow up, analysis across different messengers will also explosively grow. enhance astrophysics both be a major challenge opportunity astronomers, physicists, computer...
The Pacific Ocean Neutrino Explorer (P-ONE) collaboration was born to build a new large-scale neutrino telescope in the Ocean, at 2600 m b.s.l. Cascadia Basin, off Vancouver Island. first steps aimed feasibility study and characterisation of optical properties site with pathfinder project named STRAW (STRing for Absorption length Water), deployed 2018. During last two years, second has been developed: STRAW-b. main goal STRAW-b is validate attenuation already measured by add information on...
The instrumentation for a pathfinder mission towards possible large scale neutrino telescope named "STRings Absorption length in Water" (STRAW) is presented terms of design and performance. In June 2018 STRAW was deployed at the Cascadia Basin site operated by Ocean Networks Canada has been collecting data since then. At depth about 2600 meters, two 120 meters tall mooring lines are instrumented three "Precision Optical Calibration Modules" (POCAM) five Digital Sensors (sDOM). main...

The Pacific Ocean Neutrino Experiment (P-ONE) is an initiative by a collaboration of Canadian and German universities as well Networks Canada (ONC) to develop new large-scale neutrino telescope 2600 m below the ocean off coast western Canada. While instrumented volume needs be at least on order km³ for physics goals P-ONE met, density photo sensors kept low possible in minimize construction costs. Naturally, this puts very high demands optical properties water deployment site. Ideally,...
The Pacific Ocean Neutrino Experiment (P-ONE) is a new initiative to construct one of the world’s largest neutrino detectors in deep off coast British Columbia, Canada. Located Cascadia Basin region, P-ONE builds on number key strengths within Canadian oceanographic community. monitoring site part NEPTUNE observatory Networks Canada (ONC), which provides power and data connections various ocean sites, accessible experiments.

With the recent discovery of high-energy neutrinos extra-terrestrial origin by IceCube neutrino observatory, neutrino-astronomy is entering a new era.The highest energy observed to date exceed 1 PeV in energy, regime particular interest because should point back still elusive accelerators Galactic and extragalactic cosmic rays.This review will cover currently operating telescopes water ice, latest results from searches for flux current efforts search steady transient sources.In addition,...
An automated contact resistance measurement and recording system was designed constructed for evaluating the dry-circuit performance of electrical contacts. To assure conditions voltage across contacts limited to less than 30 millivolts regardless resistance. The signal used measure a dc biased 400 Hertz sinusoid. basic repetitive sequence operation consisted mechanically cycling switch, then measuring as falling within one an adjustable set five contiguous ranges.
A search for neutrino-induced muons in correlation with a selection of 40 gamma-ray bursts that occurred 2007 has been performed the ANTARES neutrino telescope. During period, detector consisted 5 detection lines. The telescope is sensitive to TeV--PeV neutrinos are predicted from bursts. No events were found prompt photon emission and upper limits have placed on flux fluence different models.
