Modern, ground and space based observatories have provided us with a wide range of observations from different epochs of the Universe. Despite these efforts, the Universe before Big Bang Nucleosynthesis (BBN) remains obscure to us. Then, the measurements of the primordial abundances of light elements are key when exploring theories for the early Universe. In this talk, I will discuss the...
Rare $b\to s \ell\ell$ transitions are strongly suppressed in the Standard Model (SM), making them sensitive to physics beyond the SM. Leptons from the different families have the same coupling to electroweak bosons in the SM, symmetry that is known as Lepton Flavour Universality (LFU). Precise measurements of LFU ratios in $b\to s \ell\ell$ decays provide, then, a very powerful null test of...
The nuclear equation of state (EoS) at zero temperature (T) can be expressed as the energy (E) per particle (A) or pressure (P=–∂E/∂V for A=constant) of an uniform system of neutrons and protons in their ground state. This ideal system is of particular interest for different reasons: i) Coulomb and finite-size effects are avoided (by construction) making comparisons among different models...
PhotSat is the first astrophysical satellite developed from design to operations by the Institute of Space Studies of Catalonia (IEEC) and the Catalan industrial ecosystem. The main scientific goal of the mission is to obtain a full sky photometric monitoring of the approximately 40 million brighter astrophysical sources down to magnitude 15, performing studies of transients, exoplanets, solar...
