Structures in galaxies: nature versus nurture. Input from theory and simulations
E. Athanassoula
Galaxies, in particular disc galaxies, contain a number of structures and substructures with well defined morphological, photometric and kinematic properties. Considerable theoreti…
Comparing photometric results of real and N-body bars
E. Athanassoula, D. A. Gadotti, L. Carrasco +3
We compare the results of the photometrical analysis of barred galaxies with those of a similar analysis from N-body simulations. The photometry is for a sample of nine barred gala…
Rings and spirals in barred galaxies. II. Ring and spiral morphology
E. Athanassoula, M. Romero-Gomez, A. Bosma +1
In this series of papers, we propose a theory to explain the formation and properties of rings and spirals in barred galaxies. The building blocks of these structures are orbits gu…
Setting the normalcy level of HI properties in isolated galaxies
D. Espada, L. Verdes-Montenegro, E. Athanassoula +8
Studying the atomic gas (HI) properties of the most isolated galaxies is essential to quantify the effect that the environment exerts on this sensitive component of the interstella…
Dark Matter Direct Detection Signals inferred from a Cosmological N-body Simulation with Baryons
F. -S. Ling, E. Nezri, E. Athanassoula +1
We extract at redshift z=0 a Milky Way sized object including gas, stars and dark matter (DM) from a recent, high-resolution cosmological N-body simulation with baryons. Its resolu…
The Hubble sequence: just a vestige of merger events?
F. Hammer, H. Flores, M. Puech +4
Abr: We investigate whether the Hubble sequence can be reproduced by the relics of merger events. We verify that, at zmed=0.65, the abundant population of anomalous starbursts is m…
A forming, dust enshrouded disk at z=0.43: the first example of a late type disk rebuilt after a major merger?
F. Hammer, H. Flores, Y. B. Yang +4
Abreg: By combining HST/UDF imagery with kinematics from VLT/GIRAFFE we derive a physical model of distant galaxy J033245.11-274724.0 in a way similar to what can be done in the ne…
