Valeria Ferrari Università di Roma "La Sapienza"   The recent detection by the LIGO interferometers of the gravitational wave signals emitted by coalescing compact binaries provide an entirely new instrument to observe and investigate the universe we live in, challenging or confirming our beliefs on several crucial [...]

Joel Jonas Perez Pontifical Catholic University of Peru, Lima   We investigate the present constraints from the T2K experiment for the neutrino decay scenario induced by non-diagonal couplings of Majorons to neutrinos. As novelty, on top of the typical invisible decay prescription, we add the [...]

Sam Witte IFIC   Conventional halo-independent analyses of direct dark matter detection data are subject to a number of caveats, typically limiting either the applicability or ease of interpretation. Using theorems from convex geometry, I will present a generalized halo-independent formalism that allows for the [...]

Salvador Rosauro IFT, Madrid   The baryon asymmetry of the Universe is one of the open problems of the SM of particle physics. One possible explanation for the generation of this asymmetry is leptogenesis, which arises naturally when trying to explain neutrino masses. After explaining the main features of vanilla leptogenesis, we will introduce the [...]

Jordi Miralda-Escudé (ICC, Universitat de Barcelona)   Ultralight axions have been proposed as a candidate for a constituent of the dark matter. This would imply that dark matter in galaxies oscillates like a classical wave with wavelengths on galactic scales. As the amplitudes in the modes of these waves are dynamically relaxed, we predict that a [...]

Hisakazu Minakata (IFT, Madrid)   After briefly mentioning that measurement of the neutrino parameters may have more bright feature than it was thought, I ask the question: what would be the way to conclude these neutrino endeavour?. Of course, the final goal is to understand the origin of the neutrino (and fermion) masses, but [...]

Isabella Carucci (UCL)   The nature of the most abundant components of the   Universe, dark energy and dark matter, is still to be uncovered. I   will tackle this subject considering a novel cosmological probe:  the  neutral hydrogen emitted 21cm radiation, observed with the  intensity  mapping [...]
