Differences between neutrino matter and antimatter revealed

By | Mathematics and Physics | No Comments

Researchers from the Institute of Corpuscular Physics (IFIC), from the Physics Institute of Other Energies (IFAE-Barcelona) and from the Autonomous University of Madrid, have contributed to reveal a basic property of neutrinos that had not been measured until now. It represents an important step towards learning whether neutrinos behave differently in their matter and antimatter forms. The obtained results have been published as the front-page article of journal Nature. Read More

Event Horizon Telescope reveals unexpected structures within blazar 3C279

By | Mathematics and Physics | No Comments

Around a year ago, international collaboration Event Horizon Telescope (EHT), which Valencia University takes part in, published the first image of a black hole. Now, the team has observed in detail a high-speed stream of material emerging from another supermassive black hole. The data, obtained via high-accuracy VLBI interferometry, helps to analyse the behaviour of nature in such extreme conditions. The results have been published in the Astronomy & Astrophysics journal.

Research shows the correlation between a high energy gamma burst and the development of thunderstorms

By | Mathematics and Physics | No Comments

International research involving the University of Valencia (UV) that has shown the correlation between high energy gamma burst and the development of thunderstorms at the millisecond level is on the cover of prestigious scientific journal Science in its January issue. The research addresses two violent atmospheric phenomena observed by the International Space Station (ISS), in which ultraviolet, optical and high energy emission were captured together. Read More

Researchers quantify the impact of autonomous vehicles on traffic

By | Mathematics and Physics, Technology | No Comments

Researchers of the UWICORE laboratory, of the Department of Communications Engineering and the I3E Engineering Research Centre of the Miguel Hernández University (UMH) of Elche, have proven that the coexistence between autonomous and conventional vehicles will noticeably affect the estimated effects of autonomous driving. According to this study, until at least 15% of vehicles are autonomous, no benefit will be seen regarding the fluidity of traffic and the capabilities of motorways, unless solutions are developed to guarantee an efficient coexistence of autonomous and conventional vehicles.

Astrophysics experts from all over Europe and the US meet at the University of Alicante to discuss the future of the Athena mission

By | Mathematics and Physics, Technology | No Comments

Approximately 30 astrophysics experts from all over Europe and the United States will be gathering on the University of Alicante campus from 27 to 29 November 2019 to discuss the future of the European Space Agency (ESA) mission Athena. The event is part of the European project AHEAD(Integrated Activities for the High-Energy Astrophysics Domain). One of AHEAD’s work packages is led by the UA Department of Physics, Systems Engineering and Signal Theory’s Astronomy and Astrophysics group, together with Europe’s leading research institutes.

IFIC scientists carry out the first Earth tomography with neutrinos

By | Mathematics and Physics | No Comments

Researchers from the Institute of Corpuscular Physics (UV-CSIC) and the Institute of Cosmos Sciences (UB) publish in Nature Physics the first study of the density of the planet in which they use this elementary particle, the neutrino. The method is analogous to an X-ray photograph or a CT scan. A similar technique was recently used to discover a hidden camera in the Pyramid of Cheops in Egypt. Read More
