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…
Comment on 'a slightly oblate dark matter halo revealed by a retrograde precessing Galactic disk warp' by Huang et al
Walter Dehnen, Ralph Schönrich, Ronald Drimmel +3
Huang et al. (2024) measured the derivative of the phase of the Galactic warp traced by classical Cepheids with respect to their age and interpreted it as the…
On the age distribution of Classical Cepheids in the Galaxy
Friedrich Anders, Chloé Padois, Marc Vilanova Sar +3
We revisit the problem of the positive correlation between age and Galactocentric distance seen in Galactic Classical Cepheids, which at first sight may seem counter-intuitive in t…
