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 ...
21-cm H I emission from the Damped Lyman-alpha absorber SBS 1543 593
(2001-06)
We detect 21-cm emission from the Low Surface Brightness (LSB) galaxy SBS 1543+593, which gives rise to a Damped-Ly (DLy ) absorption line in the spectrum of the background QSO HS 1543+5921 (ze = 0:807). We obtain an ...
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. ...
