Pattern speed evolution of barred galaxies in TNG50
Marcin Semczuk, Walter Dehnen, Ralph Schönrich +1
Galactic bars are found in the majority of disc galaxies. They rotate nearly rigidly with an angular frequency called pattern speed. Previous idealised simulations have shown that…
Age-morphology dependence of the Milky Way boxy/peanut bulge seen in Mira variables
Marcin Semczuk, Walter Dehnen, Ralph Schoenrich +1
We analyse the distribution of Mira variable stars in the central region of the Milky Way. We find that with increasing period, i.e. decreasing age, the Miras shift towards negativ…
The K2 Galactic Archaeology Program Data Release 3: Age-abundance patterns in C1-C8 and C10-C18
Joel C. Zinn, Dennis Stello, Yvonne Elsworth +28
We present the third and final data release of the K2 Galactic Archaeology Program (K2 GAP) for Campaigns C1-C8 and C10-C18. We provide asteroseismic radius and mass coefficients,…
Tree-ring structure of Galactic bar resonance
Rimpei Chiba, Ralph Schönrich
Galaxy models have long predicted that galactic bars slow down by losing angular momentum to their postulated dark haloes. When the bar slows down, resonance sweeps radially outwar…
