CAPA Centro de Investigacion en Fisica de Astroparticulas y Altas Energias
Research center on astrophysics, particle physics and cosmology
El viernes 28 de octubre un grupo de 40 estudiantes de Bachillerato visitó la Facultad de Ciencias para participar en las actividades de «Hands on Dark Matter» organizadas por el CAPA.
Tras unas palabras de bienvenida del Decano de la Facultad, hubo charlas a cargo de Marisa Sarsa (CAPA), Héctor Vázquez (CEFCA), y Alberto Bayo (LSC).
Georg G. Raffelt, Max-Planck-Institut für Physik. His research is in the areas of theoretical astroparticle physics and cosmology. In particular, it revolves around weakly interacting particles (neutrinos, the hypothetical axion, or weakly interacting dark matter candidates), their role in astrophysics and cosmology.
Miguel Á. Pérez Torres, research scientist at the Instituto de Astrofísica de Andalucía (IAA-CSIC, Granada, Spain) and collaborator of the DFTUZ
Abstract The Square Kilometre Array (SKA) project is an international effort to build the world’s largest radio telescope. The SKA is expected to conduct transformational science to improve our understanding of the Universe and the laws of fundamental physics, monitoring the sky in unprecedented detail and mapping it many times faster than any current facility.
The SKA will not be a single telescope, but a collection of telescopes spread over long distances in the Southern Hemisphere. In this talk, I will give an overview of the SKA project and its science goals, which range from the cradle of life in exoplanets up to shedding light on the Epoch of Reionization and the Dark Ages of the Universe.
El curso extraordinario de la Universidad de Zaragoza se ha desarrollado del 18 al 20 de julio de 2022.
Organizadores: Theopisti Dafni y Eduardo Follana.
We share the work done in a clean room to make changes inside a detector. As you can see, taking care of possible contamination is essential and, for this reason, the clean room of the Canfranc Underground Laboratory is used. The team has been working all last week and continue to work this week to get the detector ready to take data the next week. In addition to this work, they have made this fantastic video and added music. Bravo!!
TREXDM is an experiment devoted to the search for low-mass WIMPS, installed at the LSC.

We are looking excellent and motivated candidates with experimental particle physics background to join the IAXO-UZ group.
The host group at the University of Zaragoza has a leading role in the International Axion Observatory (IAXO) experiment, whose primary aim is the detection of axions emitted by the Sun.
The near-term goal of the collaboration is the construction and operation of BabyIAXO, an intermediate stage to serve as prototype of the final IAXO systems, but already with a relevant physics program in itself.
The five years duration of the project should encompass the construction, commissioning and first physics results of BabyIAXO.
The positions here offered are intended to reinforce the activities of the Zaragoza group for the preparation of the BabyIAXO experiment, which are focused in the development, preparation and characterization of a new low-background Micromegas-based x-ray detector for the focal point of BabyIAXO.
Interested candidates should send their CV, a letter of motivation to:
iaxorecruitment@unizar.es.
In addition, they should arrange for two letters of recommendation to be send to the same address.
More details on the research performed in our group can be found here:

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

El reto con el que se encuentra actualmente la física fundamental, tras el descubrimiento del Higgs, que completa el modelo estándar, es la física más allá de dicho modelo, necesaria para entender y describir la
energía oscura, la materia oscura, y las oscilaciones de neutrinos. Cada vez más la sociedad se interesa por los avances en la física fundamental y la tecnología que apoya sus experimentos. El objetivo del curso es dar una pequeña introducción de temas relacionados con la Física del Universo, proporcionando los conceptos básicos y el estado actual de nuestros conocimientos. Parte de los objetivos consisten en difundir los conceptos fundamentales, para que éstos puedan incorporarse a programas docentes de diferentes niveles educativos preuniversitarios.
Cherenkov telescopes are instruments optimized for detection of very high energy (VHE, E > 100 GeV) gamma rays from astrophysics sources. They play a crucial role in testing possible consequences of Quantum Gravity (QG), such as violation or deformation of Lorentz symmetry. In both cases, the photon dispersion relation is modified, making the photon group velocity energy dependent, and possibly modifying kinematics and dynamics of electromagnetic interactions. These tiny effects are vastly below the sensitivity of present-day laboratories. However, if real, they could be measured using VHE gamma rays of astrophysical origin. Cosmological distances that they cross serve as a natural amplifier for the QG effects. While no deviations from the special relativistic predictions have been detected, strong constraints have been set on modified photon dispersion relations.
In this session we will explain the process of testing implications of modified photon dispersion relations on VHE gamma rays using Cherenkov telescopes. We will cover different stages from observations, Cherenkov telescopes’ data analysis, statistical methods employed, and finally setting constraints on the QG energy scale.
