    Nuevas observaciones del joven y aislado cúmulo embebido GM 24
    El jovencísimo cúmulo GM 24, a una distancia de 2 kpc, se encuentra embebido en una caliente nube de CO aislada, en donde se formó hace menos de 105 años. El...

    On the origin of the absorption and emission line components in the spectra of PHL 293B
    From the structure of PHL 293B and the physical properties of its ionizing cluster and based on results of hydrodynamic models, we point at the various events...

    Peering into the origin of substructures in M31 using planetary nebulae
    Planetary nebulae (PNe) are excellent tracers to study the chemistry, kinematics, and stellar populations of galaxies. They can be used to constrain the...

    Photoionized Herbig-Haro objects in the Orion Nebula. Laboratories to better understand ionized nebulae.
    We present some results on a project based on high-resolution UVES@VLT spectroscopy and HST imaging of photoionized Herbig-Haro (HH) objects in the Orion Nebula...

    Recovering lenticular galaxies past histories using planetary nebulae kinematics: the case of NGC1023
    We present a detailed study of the lenticular galaxy NGC 1023 kinematics. To perform this analysis we use planetary nebulae (PNe). which can be observed in the...

    Rediscovering the hydrogen atom
    Common wisdom identifies hydrogen lines in photoionized region with recombination lines. However, these lines can also be excited by different atomic mechanisms...

    The 1D plane-parallel PDR model and its application
    A simple model using the balance of photodissociation assuming a one-dimensional plane-parallel model yields total hydrogen volume densities for a column of...

    The abundance of primordial helium: a keystone in our understanding of the Universe
    Primordial helium might seem to be just a tiny piece in our understanding of how the Universe was born; still, it is a piece that must fit in if we are to...

    The anomalous microwave emission in our Galaxy
    The anomalous microwave emission (AME) is an additional diffuse foreground component, originated by an emission mechanism in the ISM different from the well...
