Chemically consistent evolutionary synthesis
Fritze, U.; Weilbacher, P.; Bicker, J. (2003)To account for the range of stellar metallicities in local galaxies and for the increasing importance of low metallicities at higher redshift we present chemically consistent models for the spectral and chemical evolution ... -
Dwarf Galaxies and Star Clusters in Tidal Tails
Weilbacher, P.; Fritze, U.; Duc, P.A. (The International Astronomical Union, 2002) -
Formation of a tidal dwarf galaxy in the interacting system Arp 245 (NGC 2992/93)
Duc, P.A.; Brinks, E.; Springel, V.; Pichardo, B.; Weilbacher, P.; Mirabel, F. (2000)Among the various phenomena observed in interacting galaxies is the ejection due to tidal forces of stellar and gaseous material into the intergalactic medium and its subsequent rearranging which can lead to the formation ... -
The Formation of Tidal Dwarf Galaxies in Interacting Systems: the Case of Arp 245 (NGC 2992/93)
Brinks, E.; Duc, P.A.; Springel, V.; Pichardo, B.; Weilbacher, P.; Mirabel, F. (2001) -
Galaxy Recycling : The first sample of TDG candidates
Weilbacher, P.; Duc, P.A.; Fritze, U. (2001) -
GALEV evolutionary synthesis models – I. Code, input physics and web interface
Kotulla, R.; Fritze, U.; Weilbacher, P.; Anders, P. (2009)galev (GALaxy EVolution) evolutionary synthesis models describe the evolution of stellar populations in general, of star clusters as well as of galaxies, both in terms of resolved stellar populations and of integrated light ... -
Large Velocity Gradients in the Tidal Tails of the Interacting Galaxy AM 1353-272 (The Dentist's Chair)
Weilbacher, P.; Fritze, U.; Duc, P.A.; Fricke, K.J. (2002-10-09)We present Very Large Telescope observations of the interacting system AM 1353-272. Using the FORS2 instrument, we studied the kinematics of the ionized gas along its prominent tidal tails and discovered strikingly large ... -
On star formation rates in dwarf galaxies
Weilbacher, P.; Fritze, U. (2001) -
Optical and NIR investigation of a sample of tidal dwarf candidates
Weilbacher, P.; Fritze, U.; Duc, P.A. (2003)We analyzed a sample of 44 candidates for Tidal Dwarf Galaxies(TDGs) previously selected on optical imaging with low resolution spectroscopy. Most of the TDG candidates have the same redshift as the interacting system, 3 ... -
Stellar Populations of a Sample of Tidal Dwarf Galaxies
Weilbacher, P.; Fritze, U.; Duc, P.A. (2004) -
Tidal dwarf candidates in a sample of interacting galaxies
Weilbacher, P.; Duc, P.A.; Fritze, U.; Martin, P.; Fricke, K.J. (2000)We present deep optical B,V,R images of a sample of 10 interacting systems which were selected for their resemblance to disturbed galaxies at high redshift. Photometry is performed on knots in the tidal features of the ... -
Tidal dwarf candidates in a sample of interacting galaxies: II. Properties and kinematics of the ionized gas
Weilbacher, P.; Duc, P.A.; Fritze, U. (2003) -
Tidal Dwarf Galaxies in the Interacting System NGC 2992/2993
Brinks, E.; Duc, P.A.; Springel, V.; Pichardo, B.; Weilbacher, P.; Mirabel, F. (Astronomical Society of the Pacific, 2000)We present multi-wavelength results and numerical simulations of the interacting system NGC 2992/2992 (Arp 245). This pair is composed of two colliding spiral galaxies out of which emanate long stellar tails and a bridge. ...
