Recent observations of high-redshift galactic disks (z≈ 1–3) show a strong negative trend in
the dark-matter (DM) fraction f DM with increasing baryon surface density. For this to be true …

We present simulations of the gaseous and stellar material in several different galaxy mass
models under the influence of different tidal fly-bys to assess the changes in their bar and …

We have measured, at various wavelengths, the spiral arm pitch angles of a sample of
distant spiral galaxies from the Hubble Space Telescope eXtreme Deep Field (XDF) …

We present an account of the state of the art in the fields explored by the research
community invested in “Modeling and Observing DEnse STellar systems”. For this purpose …

Past studies have long emphasised the key role played by galactic stellar bars in the context
of disc secular evolution, via the redistribution of gas and stars, the triggering of star …

N-body simulations have shown that a bar in a galaxy can be triggered by two processes:(1)
by its own instabilities in the disk, or (2) by interactions with other galaxies. Both …

We present an N-body model for the barred Milky Way (MW) galaxy that reproduces many of
its properties, including the overall mass distribution, the disc kinematics, and the properties …
