Triggering of merger-induced starbursts by the tidal field of galaxy groups and clusters
Marie Martig, Frederic Bournaud
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 st…
Tidal debris from high-velocity collisions as fake dark galaxies: A numerical model of VirgoHI21
Pierre-Alain Duc, Frederic Bournaud
High speed collisions, although current in clusters of galaxies, have long been neglected, as they are believed to cause little damages to galaxies, except when they are repeated,…
Multiple minor mergers: formation of elliptical galaxies and constraints for the growth of spiral disks
Frederic Bournaud, Chanda J. Jog, Francoise Combes
Multiple, sequential mergers are unavoidable in the hierarchical build-up picture of galaxies, in particular for the minor mergers that are frequent and highly likely to have occur…
Rapid formation of exponential disks and bulges at high redshift from the dynamical evolution of clump cluster and chain galaxies
F. Bournaud, B. G. Elmegreen, D. M. Elmegreen
Many galaxies at high redshift have peculiar morphologies dominated by 10^8-10^9 Mo kpc-sized clumps. Using numerical simulations, we show that these "clump clusters" can result fr…
Tidal Debris posing as Dark Galaxies
Pierre-Alain Duc, Frederic Bournaud, Elias Brinks
Debris sent into the intergalactic medium during tidal collisions can tell us about several fundamental properties of galaxies, in particular their missing mass, both in the form o…
Missing Mass in Collisional Debris from Galaxies
F. Bournaud, P. -A. Duc, E. Brinks +6
Recycled dwarf galaxies can form in the collisional debris of massive galaxies. Theoretical models predict that, contrary to classical galaxies, they should be free of non-baryonic…
