The Relation of Compact Groups of Galaxies with Larger-scale Structures
Heinz Andernach, Roger Coziol
We show that Compact Groups of Galaxies (CGs) are frequently associated with larger-scale structures, and such associations become more frequent for CGs selected by the same criter…
The formation of bars and disks in Markarian starburst galaxies
R. Coziol, S. Considere, E. Davoust +1
We have proposed in a companion paper (Considere et al. 2000) that bars appeared recently in massive starburst nucleus galaxies. We now test this hypothesis on an extended sample o…
Starbursts in barred spiral galaxies IV: On young bars and the formation of abundance gradients
S. Considere, R. Coziol, T. Contini +1
The oxygen (O/H) and N/O abundance ratios along the bar of 16 barred spiral starburst galaxies are determined using long-slit spectroscopy. The abundance gradients and the spatial…
The Chemical Evolution of Galaxies by Successive Starbursts
T. Contini, R. Coziol, S. Considere +2
We propose an evolutionary scenario by successive bursts of star formation to reproduce the chemical properties of massive nearby Starburst Nucleus Galaxies (SBNGs). The N/O abunda…
The PDS starburst galaxies
R. Coziol, C. A. O. Torres, G. R. Quast +2
(Abridged) We discuss the nature of the galaxies found in the Pico dos Dias Survey (PDS) for young stellar objects. The PDS galaxies were selected from the IRAS Point Source catalo…
The Massive Nearby SBNGs: Young Galaxies in Formation
Roger Coziol, Thierry Contini, Emmanuel Davoust +1
We discuss the implications of the recent discovery that Starburst Nucleus Galaxies (SBNGs) have lower oxygen abundances than "normal galaxies" of the same morphological type. Our…
