We investigate the process of galaxy formation as can be observed in the only currently forming galaxies { the so-called Tidal Dwarf Galaxies, hereafter TDGs { through observations of the molecular gas detected via its CO ...

Galactic collisions trigger a number of phenomena, such as transportation inward of gas from distances of up to kiloparsecs from the center of a galaxy to the nuclear region, fueling a central starburst or nuclear activity. ...

We present multi-wavelength results and numerical simulations of the interacting system NGC 2992/2992 (Arp 245). This pair is composed of two colliding spiral galaxies out of which emanate long stellar tails and a bridge. ...

Among the various phenomena observed in interacting galaxies is the ejection due to tidal forces of stellar and gaseous material into the intergalactic medium and its subsequent rearranging which can lead to the formation ...

Arp 105 is an example of a collision between an infrared luminous spiral (NGC 3561A) and an elliptical (NGC 3561B) galaxy in a cluster of galaxies. Duc & Mirabel (1994) reported in this system the genesis of star{forming ...
