Deimos Ibáñez Segura defended his thesis co-directed by Adrià Rovira Garcia and Jaume Sanz Subirana on October 23 at the North Campus. Titled "Contributions to multi-purpose GNSS positioning to support multi-frequency and multi-constellation with high accuracy and integrity", the thesis presents, on the one hand, different methods for GNSS processing (multi-constellation, multi-frequency, fast convergence, integrity and maritime applications), and on the other hand the study of different components that affect GNSS positioning (such as the ionosphere, errors in the signal in space). All the processing is furthermore integrated into a tool, gLAB, aimed at both professionals and students, which already has an international impact and with the improvements made in this thesis will significantly increase its impact.

Baoying Wang defended her thesis co-supervised by Alvaro Meseguer and Fernando Mellibovsky on September 21 at the North Campus. Entitled "Transitional Coherent Structures in Shear and Centrifugally Driven Flows", the thesis computationally presents the mechanisms for creating coherent structures (invariants of the Navier-Stokes equations) pre-turbulent in rotating and/or shearing fluids.

The group of characterization of Materials of the Department of Physics participates in the project. The Muspell project's goal is to develop an innovative energy management solution that will yield substantial advantages across diverse industries and sectors, paving the way to a more sustainable future.

Physics professor Jordi José participates in an international project in which, the measurement of an unstable state of 23Mg, lasting only 10^(-14) seconds, has allowed the possible detection of gamma rays from stellar explosions to be precisely quantified

Yismaw Abera Wassie defended his thesis co-supervised by Michele Crosetto and Oriol Monserrat (CTTC) on July 24, 2023 at the Baix Llobregat Campus. The thesis, entitled "Spatio-temporal quality metrics for Satellite SAR Interferometric data", presents quality indicators for interferometric SAR (Synthetic Aperture Radar) data

An interdisciplinary team formed by the Catalan Health Department, the Catalan Health Institute and researchers of the Department of Physics of the UPC studied the relation between excess of mortality and high observed temperatures of summer 2022

David Martin Rodriguez defended his thesis supervised by Jordi José on July 7, 2023 at the Diagonal-Besòs Campus. Entitled "Hydrodynamic Models of Accretion onto Rotating Compact Stars", the thesis focuses on investigating the effects of rotation and the instabilities caused by it (meridional circulation and turbulence due to differential rotation) in type I X-ray eruptions ( or type I X-Ray Bursts), which take place on the surface of accreting neutron stars. In particular, the study focuses on the study of the observable properties (light curves, recurrence periods and nucleosynthesis) of these eruptions
