Charla de Jacobo Varela: «Synergies in plasma physics: exoplanet habitability and radio emission» 🗓


Lecturer:  Jacobo Varela Rodríguez (Universidad Carlos III, Madrid)

Abstract: This presentation discusses synergies between different plasma physics fields, emphasising in the astrophysical plasmas. In particular, exoplanet habitability is a hot topic in the scientific community, devoted to developing new observational as well as numerical models dedicated to analyzing the exoplanet environment. In the last decade, MHD models are applied to study the magnetic field generation by dynamo effect in the convective layer of stars, the production of stellar winds as well as the interaction of the stellar wind with planetary magnetospheres. We show the last advances in the modelling efforts to analysis the effect of the space weather conditions on the exoplanet habitability, that is to say the interaction of the stellar wind and the exoplanet magnetosphere. In addition, the radio emission from exoplanet magnetospheres is numerically evaluated identifying trends regarding the space weather properties

Charla de Héctor Gómez-Maluenda: Muography and Nuclear Safety: Reactors surveillance, and monitoring and waste qualification


Héctor Gómez-Maluenda ist a researcher at «Commissariat à l’énergie atomique et aux énergies alternatives» (CEA – France)

Abstract: The use of muons produced at the Earth’s atmosphere as radiation source for the scanning of big structures is usually referred as muography. Since first muography attempts by Alvarez in the 1970s, the range of applications of this technique has been broadened in the last years mainly due to the advances on the particle detectors used and to the improvements on the analysis techniques. Thus, different muography measurements have been done for vulcanology, archaeology, geotechnics or civil engineering. Among these different applications, the IRFU group (Institut de recherche sur les lois fondamentales de l’Universe – CEA – France) is developing since the last years several projects regarding Nuclear Safety. They include the characterisation of nuclear reactors and their real-time surveillance or the verification of waste containers. After a general introduction to muography, this seminar will be focused on these activities carried out at CEA and their main results, including those about first 3D reconstructions using this technique, passing from muography to muon tomography.

Charla de Maurizio Giannotti sobre axiones

Maurizio Giannotti is a Physics Professor at Barry University, Fulbright visitor at CAPA. Research in astroparticle physics, axions and axion like particles.

Abstract: The research on axions has gained great attention in the last decade. We are finally reaching the experimental capabilities to detect axions in the most motivated parameter regions and the University of Zaragoza is playing a major role in this effort. In this talk, I will present an overview of the strong CP problem and of the axion solution. I will emphasize the phenomenological aspects and in particular try to justify the selection of physically motivated axion parameter regions. I will emphasize the impact of axions on stellar evolution and the experimental potential to detect them in the near future.

Jueves 14 de octubre, en el seminario de Física Nuclear, a las 12:00.
