The International Gravitational Event Collaboration, IGEC, is a coordinated effort by research groups operating gravitational wave detectors working towards the detection of millisecond bursts of gravitational waves. Here we report on the current IGEC resonant bar observatory, its data analysis procedures, the main properties of the first exchanged data set. Even though the available data set is not complete, in the years 1997 and 1998 up to four detectors were operating simultaneously. Preliminary results are mentioned.
IceCube Collaboration Contributions to the 2009 International Cosmic Ray Conference
We analyze the effects of relative increments of mutual information among the geographical, technological, and organizational distributions of firms on the relative augmentation of regional summary turnover in terms of synergies. How do increases in synergy in international cooperation affect regional turnover? The methodological contribution of this study is that we translate the synergy (abstractly measured in bits of information) into more familiar economic terms, such as turnover for the special case of domestic-foreign collaborations. The analysis is based on Norwegian data, as Norway is a small country with an open and export-oriented economy. Data for Norway is publicly available in great detail.
The GEM (Galactic Emission Mapping) project is an international collaboration established with the aim of surveying the full sky at long wavelengths with a multi-frequency radio telescope. A total of 745 hours of observation at 408 MHz were completed from an Equatorial site in Colombia. The observations cover the celestial band $0^h < alpha < 24^h$, and $-24^{circ} 22^{prime} < delta < +35^{circ} 37^{prime}$. Preliminary results of this partial survey will be discussed. A review of the instrumental setup and a $sim 10^{circ}$ resolution sky map at 408 MHz is presented.
This list of contributions to the 37th International Cosmic Ray Conference in Berlin, Germany (12-23 July 2021) summarizes the latest results from the IceCube Neutrino Observatory. IceCube, completed 10 years ago at the geographic South Pole, comprises a surface detector designed to observe cosmic ray air showers, a cubic-kilometer array of optical sensors deployed deep in the ice sheet to observe TeV-PeV neutrinos, and a 15 Megaton deep-ice subdetector sensitive to >10 GeV neutrinos. Data from IceCube are used to investigate a broad set of key questions in physics and astrophysics, such as the origins of galactic and extragalactic cosmic rays, the fundamental properties of neutrinos, and searches for physics beyond the Standard Model. The papers in this index are grouped topically to highlight IceCube contributions related to neutrino and multi-messenger astrophysics, cosmic-ray physics, fundamental physics, education and public outreach, and research and development for next-generation neutrino observatories. Contributions related to IceCube-Gen2, the future extension of IceCube, are available in a separate collection.
Index entry listing the contributed papers of the MAGIC collaboration to the 31th International Cosmic Ray Conference (ICRC 2009), July 7-15 2009, Lodz, Poland. The individual papers are sorted by subject: Overview and Highlight Papers; MAGIC-II Status and Components; Software and Analysis Techniques; Technical Developments; Scientific Results. This HTML document includes clickable links to the papers that exist on the astro-ph arXiv. We hope that this will make it easy to access the MAGIC contributions in a systematic way.
