    Photoionization Models of Metal-poor Extragalactic H 0 Regions and the Primordial Helium Abundance
    We discuss the effects of collisional enhancement of Balmer lines on the determination of the primordial helium abundance. To this aim, we present a...

    Photoionization Models of NGC 2363
    We compute photoionization models for the giant extragalactic H II region NGC 2363, and compare them with optical observational data. We show that models...

    Photoionization Models of NGC 346
    We have compared direct estimates of the ionizing photon flux from the stars observed within the H II region NGC 346 in the Small Magellanic Cloud with its...

    Photoionization of the Diffuse Interstellar Gas in Spirals by Lyman Photons Escaping from H II Regions
    The existence of an extended component of diffuse ionized gas (DIG) is a well-known property of spiral galaxies. The integrated ensuremath {{H}alpha }...

    Photoionized Herbig-Haro objects in the Orion Nebula through deep high-spectral resolution spectroscopy
    We analyze the physical conditions (density and temperature), chemical abundances, dynamics and kinematics of gas in HH529II, HH529III and HH204, photoionized...

    Photoionized Herbig-Haro objects in the Orion Nebula through VLT's deep spectroscopy I: HH529 II-III
    Using the Ultraviolet Visual Echelle Spectrograph (UVES) at the Very Large Telescope (VLT), we study the photoionized Herbig-Haro object HH529 in two associated...

    Photometric analysis of Abell 1689
    We carried out a photometric analysis of a sample of early-type galaxies in Abell~1689 at z = 0.183, using HST/ACS archive images in the rest-frame V band. We...

    Photometric and Polarimetric Observations of the Wolf-Rayet Eclipsing Binary HD 5980 in the Small Magellanic Cloud
    We present results of photometry and photopolarimetry of the Wolf-Rayet eclipsing binary system HD 5980 in the Small Magellanic Cloud, which underwent an...
