Journal ArticleDOI
Abundant molecular gas in tidal dwarf galaxies: On-going galaxy formation
Jonathan Braine,Pierre-Alain Duc,Ute Lisenfeld,Vassilis Charmandaris,O. Vallejo,Stephane Leon,Elias Brinks +6 more
TL;DR: In this paper, the authors investigated 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.
Journal ArticleDOI
Dynamics of embedded bars and the connection with AGN - I. ISAAC/VLT stellar kinematics
Eric Emsellem,D. Greusard,Francoise Combes,D. Friedli,Stephane Leon,Emmanuel Pecontal,Herve Wozniak +6 more
TL;DR: In this article, the authors present stellar kinematical profiles of four galaxy hosts of active galactic nuclei, using the 12 CO bandhead around 2.3 μ m with the ISAAC/VLT spectrograph.
Journal ArticleDOI
The AMIGA project. I. Optical characterization of the CIG catalog
Lourdes Verdes-Montenegro,J. W. Sulentic,Ute Lisenfeld,Ute Lisenfeld,Stephane Leon,Daniel Espada,Emilio José García,J. Sabater,S. Verley +8 more
TL;DR: In this paper, the authors derived the optical luminosity function (OLF) for the catalog of isolated galaxies (CIG) from the AMIGA data and compared it with the results of other studies of the OLF for lower density environments.
