Search for PeV-EeV tau neutrinos and optical transients from violent objects with ashra-1

ASHRA-1 COLLABORATION)

研究成果: Conference contribution

抜粋

Ashra is a project to build an unconventional optical telescope complex that images a very wide field of view (FOV), covering 77% of the sky, yet with the angle resolution of a few arcmin, with the use of image intensifier and CMOS technology. The project primarily aims to observe Cherenkov and fluorescence light from air-shower developments. It can also be used to monitor optical transients in the wide FOV. The detector has great sensitivity in the PeV-EeV region using the Earth-skimming (ES) tau neutrino technique, and can be used to search for neutrinos originating from hadron acceleration in astronomical objects. Additional advantages are perfect shielding of cosmic ray secondaries, precision determination of arrival direction, and negligible atmospheric neutrino background. Ashra-1 completes its 3rd observation period, the first dedicated to taking physics data for PeV-EeV tau neutrinos with the best instantaneous sensitivity and optical transients, in March 2013. From January 2012 until end of March 2013, about 1950 hours of data have been taken out of 2006 hours possible due to light constraints. For optical transients, we have 3763 additional hours of data taken from 2008 until 2011. We present the analysis of these data taken for the PeV-EeV tau neutrinos and optical transients.
