Description
We use Hα measurements of complete sets of HII regions in disc galaxies to compute the fraction of ionizing photons which escape from them using the hypothesis of density bounding. The escaping flux is more than enough to ionize the observed diffuse ionized gas (DIG) and the balance implies that an important fraction of the flux escapes into the intergalactic medium (IGM).

    The Large Interferometer For Exoplanets (LIFE) is a proposed space mission that enables the spectral characterization of the thermal emission of exoplanets in the solar neighborhood. The mission is designed to search for global atmospheric biosignatures on dozens of temperate terrestrial exoplanets and it will naturally investigate the diversity of
