Chemically consistent evolution of galaxies: II. Spectrophotometric evolution from zero to high redshift
Jens Bicker, Uta Fritze - v. Alvensleben, Claudia S. Moeller +1
We present a new generation of chemically consistent evolutionary synthesis models for galaxies of various spectral types from E through Sd. The models follow the chemical enrichme…
The regeneration of stellar bars by tidal interactions. Numerical simulations of fly-by encounters
I. Berentzen, E. Athanassoula, C. H. Heller +1
We study the regeneration of stellar bars triggered by a tidal interaction, using numerical simulations of either purely stellar or stellar+gas disc galaxies. We find that interact…
Numerical simulations of interacting gas-rich barred galaxies. Vertical impact of small companions
I. Berentzen, E. Athanassoula, C. H. Heller +1
We investigate the dynamical effects of an interaction between an initially barred galaxy and a small spherical companion using an N-body/SPH algorithm. In the models described her…
Faint companions in the close environment of star-forming dwarf galaxies: possible overlooked starburst triggers?
K. G. Noeske, J. Iglesias-Paramo, J. M. Vilchez +2
Using the NASA Extragalactic Database, we have searched the close environment of 98 star-forming dwarf galaxies (SFDGs) from field- and low density environments for companion galax…
Optical & NIR photometry of the interacting Dwarf Galaxies II Zw 70/II Zw 71
P. Papaderos, K. G. Noeske, L. M. Cairos +2
We obtained deep optical and NIR images of the pair of blue compact dwarf (BCD) galaxies II Zw 70 and II Zw 71 in order to study the effects of interaction on the structural proper…
Optical & NIR Surface Photometry of I Zw 18
P. Papaderos, Yu. I. Izotov, K. G. Noeske +2
Using HST and ground-based optical and NIR data, we investigate whether the blue compact dwarf (BCD) galaxy I Zw 18 has an extended low-surface-brightness (LSB) older stellar popul…
