    Formation and evolution of S0 galaxies: a SAURON case study of NGC 7332
    We present SAURON integral-field observations of the S0 galaxy NGC 7332. Existing broad-band ground-based and Hubble Space Telescope (HST) photometry reveals a...

    Formation and Evolution of Structures in the Universe
    We summarize our work on structures in different stages of aggregation, and spanning a wide range in redshift. We emphasize our work on high resdhift clusters...

    Formation of S0 galaxies through mergers. Antitruncated stellar discs resulting from major mergers <xref ref-type="fn" rid="FN1">
    Context. Lenticular galaxies (S0s) are more likely to host antitruncated (Type III) stellar discs than galaxies of later Hubble types. Major mergers are...

    Formation of S0 galaxies through mergers. Bulge-disc structural coupling resulting from major mergers
    Context. Observations reveal a strong structural coupling between bulge and disc in S0 galaxies, which seems difficult to explain if they have formed from...

    Formation of S0 galaxies through mergers. Evolution in the Tully-Fisher relation since z ∼ 1
    Context. Lenticular (S0) galaxies are known to derive from spiral galaxies. The fact that S0s nearly obey the Tully-Fisher relation (TFR) at z ∼ 0 (as spirals...

    Formation of S0 galaxies through mergers. Explaining angular momentum and concentration change from spirals to S0s
    The CALIFA team has recently found that the stellar angular momentum and concentration of late-type spiral galaxies are incompatible with those of lenticular...
  • Publication
    Formation of S0 galaxies through mergers. Morphological properties: tidal relics, lenses, ovals, and other inner components
    Context. Major mergers are popularly considered too destructive to produce the relaxed regular structures and the morphological inner components (ICs) usually...

    Formation of Slowly Rotating Elliptical Galaxies in Major Mergers. A Resolution Study
    We study resolution effects in numerical simulations of gas-rich (20% of the total baryonic mass) major mergers, and show that the formation of slowly-rotating...

    Formation of Star Clusters in the Large Magellanic Cloud and Small Magellanic Cloud. I. Preliminary Results on Cluster Formation from Colliding Gas Clouds
    We demonstrate that single and binary star clusters can be formed during cloud-cloud collisions triggered by the tidal interaction between the Large and Small...
