A SEARCH FOR H i IN FIVE ELLIPTICAL GALAXIES WITH FINE STRUCTURE
We report on VLA H i spectral line observations of five early-type galaxies classified as optically peculiar because of the presence of jets, ripples, or other optical fine structure. We detect H i within the primary beam (300 half-power beamwidth) in four of the five systems. However, in only one case is this gas associated with the targeted elliptical galaxy. In the other cases the H i is ass...
متن کاملA SEARCH FOR H i IN FIVE ELLIPTICALS WITH FINE STRUCTURE
We report on VLA H i spectral line observations of five early-type galaxies classified as optically peculiar due to the presence of jets, ripples or other optical “fine structure”. We detect H i within the primary beam (30 HPBW) in four of the five systems. However, in only one case is this gas associated with the targeted elliptical galaxy. In the other cases the H i is associated with a nearb...
متن کاملStructure, Formation and Ages of Elliptical Galaxies
The structural properties of elliptical galaxies are consistent with their formation in a merging hierarchy. In this picture, the role of gaseous processes and dissipation decreased with increasing mass creating preferentially rotationally flattend disky ellipticals (and S0s) at lower luminosities and boxy, anisotropic ellipticals (often with peculiar kinematics) at higher luminosities. However...
متن کاملThe Central Structure of Elliptical Galaxies and the Stellar-Dynamical Search for Supermassive Black Holes
Elliptical galaxies are divided into two types: galaxies with steep prooles that show no breaks in slope or that have extra light at small radii compared to a S ersic function t and galaxies that show a break from steep outer prooles to shallow inner prooles. These cuspy cores are important because they are a sign of undiscovered physical processes. Prooles with extra light near the center rese...
متن کاملSpitzer Imaging of nearby ULIRGs and their Progeny: Fine-Structure Elliptical Galaxies
We present results from two mid-infrared imaging programs of ultraluminous infrared galaxies (ULIRGs) and fine-structure elliptical galaxies. The former are known to nearly all be recent mergers between two gas-rich spiral galaxies, while the latter are also believed to be even more aged merger remnants. An examination of these two classes of objects, which may represent different stages of the...
