2.3.6 Specific Sources of Extraterrestrial Particles

Search for extraterrestrial point sources of neutrinos with AMANDA-II.

We present the results of a search for point sources of high-energy neutrinos in the northern hemisphere using AMANDA-II data collected in the year 2000. Included are flux limits on several active-galactic-nuclei blazars, microquasars, magnetars, and other candidate neutrino sources. A search for excesses above a random background of cosmic-ray-induced atmospheric neutrinos and misreconstructed...

Search for Extraterrestrial Particles in Sediment from the South Pacific

Introduction: Micrometeorites and IDPs dominate the flux of extraterrestrial material to the earth [1] and have long been collected from the stratosphere, polar ice, and deep-sea sediments [e.g., 2]. Recent efforts have focused on locating new locations from which cosmic dust grains can be easily collected and identified. Certain regions in the Pacific Ocean with limited sources of terrestrial ...

Extraterrestrial Assay Candidates : No Transmissions from Intrinsically Steady Sources

This paper reports new, more sensitive observations of nine of the eleven extrastatis-tical signals in the Megachannel Extraterrestrial Assay (META). These extrastatistical signals had all of the expected characteristics of a transmission from an extraterrestrial transmitter, except that they did not repeat. Cordes, Lazio, & Sagan showed that this lack of repeatability could be explained by the...

Health claims on food products are often used as a means to highlight scientifically proven health benefits associated with consuming those foods. But do consumers understand and trust health claims? This paper provides an overview of recent research on consumers and health claims including attitudes, understanding and purchasing behaviour. A majority of studies investigated selective product–c...
