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…)

How dark matter came to be: Experimental constraints on dark matter production mechanisms
Lecturer: David G. Cerdeño, UAM-IFT
Abstract: : Despite various decades of ongoing experimental efforts, the nature of the dark matter in the Universe remains unknown. Direct and indirect search methods have explored models of particle dark matter with increasing sensitivity, leading to strong constraints on their parameters. In this seminar I will review different ways in which dark matter might have been produced in the early Universe. We will then discuss if (and how) these mechanisms have been probed by current experimental searches.

SKA: the mother of all radio telescopes
Miguel Á. Pérez Torres is a research scientist at the Instituto de Astrofísica de Andalucía (IAA-CSIC, Granada, Spain) and collaborator of the DFTUZ
Abstract : The Square Kilometre Array (SKtA) project is an international effort to build the world’s largest radio telescope. The SKA is expected to conduct transformational science to improve our undersanding 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.

QCD axions as dark matter and their potential detection by gravitational microlensing
Jordi Miralda Escudé es ICREA Professor of Astrophysics Institut de Ciències del Cosmos
Abstract:The most distant single stars we have observed are in cases of extreme gravitational lensing magnification, when the source star crosses a lensing caustic of a cluster of galaxies that is affected by microlensing. This has enabled detections of stars at redshifts above unity with HST, and now with JWST to even fainter levels. If dark matter is smoothly distributed, microlensing should be caused only by intracluster stars, with rates and lightcurves of caustic crossings that have precise statistical predictions. Deviations from the shapes and other characteristics of these lightcurves are then a powerful probe to small-scale granularity in the dark matter, which is unavailable through other astronomical observations. In particular, if the QCD axion is present in the dark matter, minihalos predicted to have formed around the epoch of equalization can affect the lightcurves of stars that are supermagnified when crossing microlensing caustics.

Abstract: The Large Hadron Collider (LHC) at CERN, the largest and most complex machine ever built will extend the frontiers of particle physics with its unprecedented high energy and luminosity. The ATLAS experiment is the largest particle detector at LHC, targets to detect the tiny subatomic particles and study the fundamental constituents of matter to better understand the rules behind their interactions. The ATLAS experiment at the LHC has a broad search program covering a wide variety of models of physics beyond the Standard Model (BSM). Various BSM theories predict unique signatures that are difficult to reconstruct and for which estimating the background rate is also a challenge. With the large amount of data gathered by the Run-2 of the LHC, the production of four top quarks (𝒕𝒕 𝒕𝒕 ) has become a very interesting probe of the Standard Model (SM) and beyond. In the SM of particle physics, 𝒕𝒕 𝒕𝒕 production is an extremely rare process with a cross section of approximately 12 fb. In extensions of the SM with top-philic new states, the four-top production rate can be enhanced considerably. Highlights from recent new physics searches with the ATLAS detector at the CERN LHC will be presented. They include searches for the SM 𝒕𝒕 𝒕𝒕 and BSM 𝒕𝒕 𝒕𝒕 , among others. Results are based on analysis of proton-proton collision data recorded at a centre-of-mass energy of 13 TeV.

Antoine Kouchner , Laboratoire Astroparticule et Cosmologie (APC) Paris, is the ANTARES experiment spokesperson
Abstract: Messengers of the infinitely small, neutrinos provide us with valuable insights into the fundamental laws of physics. Messengers of the infinitely large, traveling on cosmological distances, they are privileged probes of cataclysmic astrophysical phenomena.
Neutrino Telescopes, buried deep in the sea/lake/ice are trying to meet this double challenge. These detectors consist of a 3D matrix of photomultipliers that detect the Cherenkov light inferred by the displacement of charged particles produced when neutrinos interact inside or around the detector.
After a brief historical introduction, I will review the latest results from the first generation deep-sea neutrino telescope ANTARES and the expectations and status of the next generation detector KM3NeT, both immersed in the Mediterranean Sea. In this context, synergies with Earth and Sea sciences will be mentioned.
Some emphasis will be placed on the potential of neutrino telescopes for the determination of the neutrino mass ordering through oscillation studies of atmospheric neutrinos in the GeV range (KM3NeT/ORCA) in the Mediterranean Sea.
