Formation of late-type spiral galaxies: gas return from stellar populations regulates disk destruction and bulge growth (2009)

Martig, Marie, Bournaud, Frederic

Spiral galaxies have most of their stellar mass in a large rotating disk, and only a modest fraction in a central spheroidal bulge. This poses a major challenge for cosmological models of galaxy...

The thick disks of spiral galaxies as relics from gas-rich, turbulent, clumpy disks at high redshift (2009)

Bournaud, Frederic, Elmegreen, Bruce G., Martig, Marie

The formation of thick stellar disks in spiral galaxies is studied. Simulations of gas-rich young galaxies show formation of internal clumps by gravitational instabilities, clump coalescence into a...

Morphological quenching of star formation: making early-type galaxies red (2009)

Martig, Marie, Bournaud, Frederic, Teyssier, Romain, Dekel, Avishai

We point out a natural mechanism for quenching of star formation in early-type galaxies. It automatically links the color of a galaxy with its morphology and does not require gas consumption, removal...

Numerical simulations of galaxy evolution in cosmological context (2008)

Martig, Marie, Bournaud, Frederic, Teyssier, Romain

Large volume cosmological simulations succeed in reproducing the large-scale structure of the Universe. However, they lack resolution and may not take into account all relevant physical processes to...

Triggering of merger-induced starbursts by the tidal field of galaxy groups and clusters (2007)

Martig, Marie, Bournaud, Frederic

Star formation in galaxies is for a part driven by galaxy mergers. At low redshift, star formation activity is low in high-density environments like groups and clusters, and the star formation...
