A Vertical Resonance Heating Model for X- or Peanut-Shaped Galactic Bulges
Alice C. Quillen, Ivan Minchev, Sanjib Sharma +2
We explore a second order Hamiltonian vertical resonance model for X-shaped or peanut-shaped galactic bulges. The X-shape is caused by the 2:1 vertical Lindblad resonance with the…
The age structure of stellar populations in the solar vicinity. Clues of a two-phase formation history of the Milky Way disk
M. Haywood, P. Di Matteo, M. Lehnert +2
We analyze high quality abundances data of solar neighborhood stars and show that there are two distinct regimes of [alpha/Fe] versus age which we identify as the epochs of the thi…
On the self-regulation of intense star-formation in galaxies at z=1-3
M. D. Lehnert, L. Le Tiran, N. P. H. Nesvadba +3
(abridged) We have analyzed the properties of the rest-frame optical emission lines of a sample of 53 intensely star forming galaxies at z=1.3 to 2.7 observed with SINFONI on the E…
Signatures of radial migration in barred galaxies: Azimuthal variations in the metallicity distribution of old stars
P. Di Matteo, M. Haywood, F. Combes +2
By means of N-body simulations, we show that radial migration in galaxy disks, induced by bar and spiral arms, leads to significant azimuthal variations in the metallicity distribu…
