Inner bars also buckle. The MUSE TIMER view of the double-barred galaxy NGC 1291

J. Mendez-Abreu, A. de Lorenzo-Caceres, D. A. Gadotti +8

Double bars are thought to be important features for secular evolution in the central regions of galaxies. However, observational evidence about their origin and evolution is still…

Time Inference with MUSE in Extragalactic Rings (TIMER): Properties of the Survey and High-Level Data Products

Dimitri A. Gadotti, Patricia Sánchez-Blázquez, Jesús Falcón-Barroso +14

The Time Inference with MUSE in Extragalactic Rings (TIMER) project is a survey with the VLT-MUSE integral-field spectrograph of 24 nearby barred galaxies with prominent central st…

A dynamical mechanism for the origin of nuclear rings

Mattia C. Sormani, Emanuele Sobacchi, Francesca Fragkoudi +4

We develop a dynamical theory for the origin of nuclear rings in barred galaxies. In analogy with the standard theory of accretion discs, our theory is based on shear viscous force…

Searching for a kinematic signature of the moderately metal-poor stars in the Milky Way bulge using N-body simulations

Ana Gomez, Paola Di Matteo, Mathias Schultheis +3

Although there is consensus that metal-rich stars in the Milky Way bulge are formed via secular evolution of the thin disc, the origin of their metal-poor counterparts is still und…

Phylogeny of the Milky Way's inner disk and bulge populations: Implications for gas accretion, (the lack of) inside-out thick disk formation, and quenching

Misha Haywood, Paola Di Matteo, Matthew Lehnert +3

We show that the bulge and the disk of the Milky Way (MW) at R7~kpc are well described by a unique chemical evolution and a two-phase star-formation history (SFH). We arg…

The disc origin of the Milky Way bulge: Dissecting the chemo-morphological relations using N-body simulations and APOGEE

F. Fragkoudi, P. Di Matteo, M. Haywood +4

There is a long-standing debate on the origin of the metal-poor stellar populations of the Milky Way (MW) bulge, with the two leading scenarios being that these populations are eit…
