High-resolution Hi Mapping of Ngc 4038/9 (“the Antennae”) and Its Tidal Dwarf Galaxy Candidates
We present new VLA C+D-array H i observations and optical and NIR imaging of the well known interacting system NGC 4038/9, “The Antennae”. At low spatial resolution (∼ 40), the radio data reach a limiting column density of ∼ 10 cm (2.5σ), providing significantly deeper mapping of the tidal features than afforded by earlier H i maps. At relatively high spatial resolution (∼ 10), the radio data r...
متن کاملTidal Dwarf
We review the observational evidences for tidal dwarf galaxies, a class of small galaxies formed out of the tidal debris of collisions between massive galaxies. Tidal dwarfs are found far from the interacting parent galaxies, associated to massive clouds of atomic hydrogen located at the tip of long tidal tails. These newly formed galaxies are among the best cases for the study of galaxy format...
متن کاملA Spatial Characterization of the Sagittarius Dwarf Galaxy Tidal Tails
We measure the spatial density of F turnoff stars in the Sagittarius dwarf tidal stream, from Sloan Digital Sky Survey (SDSS) data, using statistical photometric parallax. We find a set of continuous, consistent parameters that describe the leading Sgr stream’s position, direction, and width for 15 stripes in the North Galactic Cap, and 3 stripes in the South Galactic Cap. We produce a catalog ...
متن کاملMolecular Gas in Tidal Dwarf Galaxies: On-going Galaxy Formation
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 (Carbon Monoxide) emission. Molecular gas is a key element in the galaxy formation process, providing the link between a cloud of gas and a bona fide galaxy. We have now detec...
