    The Ionized Gas in Nearby Galaxies as Traced by the [N II] 122 and 205 μm Transitions
    The [N ii] 122 and 205 μm transitions are powerful tracers of the ionized gas in the interstellar medium. By combining data from 21 galaxies selected from the...

    The ionized gas in the CALIFA early-type galaxies. I. Mapping two representative cases: NGC 6762 and NGC 5966
    As part of the ongoing CALIFA survey, we have conducted a thorough bidimensional analysis of the ionized gas in two E/S0 galaxies, NGC 6762 and NGC 5966, aiming...

    The ionized intergalactic gas: baryonic dark matter.
    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...

    The ISLANDS Project. I. Andromeda XVI, An Extremely Low Mass Galaxy Not Quenched by Reionization
    Based on data aquired in 13 orbits of Hubble Space Telescope time, we present a detailed evolutionary history of the M31 dSph satellite Andromeda XVI, including...

    The ISLAnds Project. III. Variable Stars in Six Andromeda Dwarf Spheroidal Galaxies
    We present a census of variable stars in six M31 dwarf spheroidal satellites observed with the Hubble Space Telescope. We detect 870 RR Lyrae (RRL) stars in the...
