    The origin of the cold spot in the Corona Borealis supercluster
    The Very Small Array (VSA) detected a cold spot in the Cosmic Microwave Background (CMB) towardsthe Corona Borealis supercluster of galaxies. The origin of this...

    The Origin of the Diffuse Hα in Spirals
    Using high-quality H_α images of five spiral galaxies, we have studied the luminosity and distribution of the emission from diffuse ionized gas (DIG). The...

    The origin of the IR emission of low-luminosity AGN
    To test recent suggestions that the infrared emission of low-luminosity AGN arises in a truncated thin accretion disk, we compare recent, high-resolution IR...

    The origin of the most luminous Planetary Nebulae
    As part of a systematic effort to characterize the properties and progenitors of the most luminous planetary nebulae (PNe), we obtained a sample among the...

    The origin of the most luminous planetary nebulae: M31
    The Planetary Nebulae Luminosity Function (PNLF) is an important standard candle on the extragalactic distance ladder. Its use is based on the empirical...

    The origin of the solar cyclic activities: the DynaMICS project
    In order to better estimate the earth climatic variations at scales corresponding to decennia or centuries it appears more and more important to understand the...

    The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
    Modern cosmology has sharpened questions posed for millennia about the origin of our cosmic habitat. The age-old questions have been transformed into two...
  • Publication
    The Origins and Evolution of Fossil Galaxy Groups
    Fossil groups (FGs) are galaxy systems with masses and X-ray haloes comparable to to those of groups and clusters of galaxies, but whose optical light is...

    The Origins of Planetary Nebulae in the Inner and Outer Disks of M 31
    The planetary nebulae (PNe) of M 31 are receiving considerable attention as probes of its structure and chemical evolution in a galactic environment that is...
