Recovering the origins of the lenticular galaxy NGC 3115 using multi-band imaging
Maria Luisa Buzzo, Arianna Cortesi, Jose A. Hernandez-Jimenez +16
A detailed study of the morphology of lenticular galaxies is an important way to understand how this type of galaxy formed and evolves over time. Decomposing a galaxy into its comp…
The relative efficiencies of bars and clumps in driving disc stars to retrograde motion
Karl Fiteni, Joseph Caruana, João A. S. Amarante +2
The presence of stars on retrograde orbits in disc galaxies is usually attributed to accretion events, both via direct accretion, as well as through the heating of the disc stars.…
Co-formation of the thin and thick discs revealed by APOGEE-DR16 and Gaia-DR2
Leandro Beraldo e Silva, Victor P. Debattista, David Nidever +2
Since thin disc stars are younger than thick disc stars on average, the thin disc is predicted by some models to start forming after the thick disc had formed, around 10 Gyr ago. A…
Box/peanut-shaped bulges in action space
Victor P. Debattista, David J. Liddicott, Tigran Khachaturyants +1
We introduce the study of box/peanut (B/P) bulges in the action space of the initial axisymmetric system. We explore where populations with different actions end up once a bar form…
