Abundant molecular gas in tidal dwarf galaxies: On-going galaxy formation
(2001-10)
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 ...
H I Recycling: Formation of Tidal Dwarf Galaxies
(Astronomical Society of the Pacific, 2001)
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. ...
Tidal Dwarf Galaxies in the Interacting System NGC 2992/2993
(Astronomical Society of the Pacific, 2000)
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. ...
Formation of a tidal dwarf galaxy in the interacting system Arp 245 (NGC 2992/93)
(2000)
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 ...
