«La física del Universo», cursos extraordinarios de la Universidad de Zaragoza en Jaca

 

Curso extraordinario organizado por el CAPA del 18/07/2022 al 20/07/2022 y coordinado por  Theopisti Dafni y Eduardo Follana Adín.
Objetivos: 

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.

Charla de Tomislav Terzić : «Measuring Lorentz invariance violation with Cherenkov telescopes – from observations to setting constraints»

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.

Charla de Diego Blas: «Soundscape of gravitational waves: a new tool to access the fundamental blocks of the Universe»

Diego Blas is a researcher at UAB (Universidad Autónoma de Barcelona) and IFAE (Instituto de Física de Altas Energías). His research interests are in theoretical physics, gravitation and cosmology.

Abstract: In this talk, current and future efforts to detect gravitational waves from Earth and space observatories will be reviewed. Diego will also emphasise the physical consequences of these searchers, in particular regarding fundamental physics (primordial cosmology, dark matter, modified gravity…)

Charla de Carlos López Sanjuan: La evolución espectral de enanas blancas con J-PLUS

J-PLUS

Dr. Carlos López Sanjuan is a researcher at CEFCA (Centro de Estudios de Física del Cosmos de Aragón).

Abstract: White dwarfs are the degenerate compact remnants of stars with masses below 8 Msun. They do not have an internal source of energy and just cool down with time. In addition, they show a diversity of atmospheric compositions in their spectra, with sources presenting hydrogen (H) lines (DA type), helium (He) lines (DO and DB type), metal lines (DZ type), and featureless spectra (DC type) among others. In this seminar we present our recent work about the spectral evolution of white dwarfs with effective temperature (i.e., their age) using the Javalambre Photometric Local Universe Survey (J-PLUS). We analysed 5926 white dwarfs with r <= 19.5 mag in common between the white dwarf catalogue presented in Gentile Fusillo et al. 2021, defined from Gaia EDR3, and J-PLUS DR2. We estimated their effective temperature (Teff), surface gravity, parallax, and spectral type; and the probability of having a H-dominated atmosphere (p_H) for each source. Our analysis yields a 21 +- 3% increase in the fraction of He-dominated white dwarfs from Teff = 20000 K to  Teff = 5000 K.

2nd edition of the International INFN «School of Underground Physics: Theory and experiments» (SoUP2022)

The 2nd edition of the International INFN «School of Underground Physics: Theory and experiments» (SoUP2022) will  take place hopefully in person, at the INFN Laboratori Nazionali del Gran Sasso (Italy) from June 20th to June 24th, 2022. It is addressed to PhD students, post-docs and young researchers involved in the field from all over the world.
The School is organised with lectures + a hands-on session in Statistics. It also includes a poster session and a visit to the LNGS underground experiments and facilities.
Registration is now open, with deadline April 15th.
It is foreseen to have the school in person, with at most 50 attending people.
In case of increased restrictions due to COVID19 pandemic the School will be held fully online (no «mixed» solution is foreseen). The final decision will be taken by early May.

Feebly Interacting Sectors Impact on Cosmology & Astrophysics.

Virtual workshop (1st-4th March 2022)

Different types of astrophysical environments—such as horizontal branch stars, the sun, supernovae (SNe), neutron stars, black holes—offer different guises to explore fundamental physics, and in particular feebly interacting sectors.

A collaborative effort between particle physicists, astrophysicists and astronomers is highly desirable. This interaction can help refine existing ideas, identify the most promising candidate theories and come up with new possible signatures from astrophysical objects.

The goal of this workshop is to bring together the relevant communities, paving the way for a new decade in fundamental physics.
