An international scientific team, in which Yuri Cavecchi, from the physics department of the UPC has participated, and led by the Instituto de Astrofísica de Canarias (IAC), has found a neutron star that steals matter from a companion star in a violent and unstable. This process, previously only observed in black holes. The study is published in the journal Nature.

A team of researchers from the Universitat Politècnica de Catalunya (Spain), Universidade Estadual de Campinas (Brazil) and Stanford University (USA) performed advanced quantum atomistic simulations to assess the Bose-Einstein condensate fraction of solid helium at zero temperature containing dislocations, a defective system that previously had been proposed to be “supersolid”

Giulio Tirabassi and Cristina Masoller have created an algorithm based on the analysis of satellite data provided by NASA's MODIS instrument that allows preventing the definitive destruction of natural environments

A team of researchers from UPC in Barcelona and EPFL in Lausanne built a new theory to explain the finite-temperature properties in terms of microscopic excitations of bosons in one dimension

A few hundred astronomy professionals have designed and planned a total of five years of operations for the WEAVE spectrograph, a powerful instrument recently installed at the Canary Islands Observatory.

The researchers Siddharth Pitta, Jose I. Rojas, Francesc Roure, Daniel Crespo, and Magd Abdel Wahab, from the Group of Materials Characterization of the UPC, the Materials Strength Laboratory of the UPC, and the Ghent University, have made new progresses in the characterization of the fatigue response of aircraft repair patches made of carbon fiber reinforced epoxy (CFRE) and aluminum alloy on aircraft airframe substrates made as well of CFRE and aluminum alloy

Researchers Y. J. Duan, E. Pineda and D. Crespo, from the Group of Materials Characterization of the UPC, have made new progress to understand the mechanical properties of high-entropy metallic glasses. The work clarifies the correlation between the fraction of liquid-like zones, i.e. the fraction of atoms that can easily rearrange under the effect of external forces, and the secondary or β relaxation observed in these materials. Besides, the work reveals the high-entropy effect on the supercooled liquid dynamics of the metallic melt.
