NOEMA$^\rm{3D}$: A deep view of cold gas flows in a barred spiral galaxy at

Stavros Pastras, Reinhard Genzel, Linda J. Tacconi +35

We present a deep, high-resolution CO(4-3) IRAM-NOEMA observation of a main sequence, barred, spiral galaxy at , with an on-source integration time of hou…

Gasflows in Barred Galaxies with Big Orbital Loops-A Comparative Study of Two Hydrocodes

Stavros Pastras, Panos A. Patsis, E. Athanassoula

We study the flow of gas in a barred-galaxy model, in which a considerable part of the underlying stable periodic orbits have loops where, close to the ends of the bar, several orb…

Morphologies arising from the gas flow in the innermost kiloparsec of barred galaxy models

Stavros Pastras, Panos A. Patsis, E. Athanassoula

Context. We study a series of response models to investigate the formation of specific morphological features in the central 1 kpc region of the gas component in barred spiral gala…

The evolution of the phase space structure along pitchfork and period-doubling bifurcations in a 3D galactic bar potential

Henok Tenaw Moges, Matthaios Katsanikas, Panos Patsis +2

We investigate how the phase space structure of a 3D autonomous Hamiltonian system evolves across a series of successive 2D and 3D pitchfork and period-doubling bifurcations, as th…

Orbit evolution in growing stellar bars: Bar-supporting orbits at the vertical ILR region

Thanos Manos, Charalampos Skokos, Panos Patsis

We investigate the evolution of orbital shapes at the Inner Lindblad Resonance region of a rotating three-dimensional bar, the mass of which is growing with time. We evaluate in ti…

Chaoticity in the vicinity of complex unstable periodic orbits in galactic type potentials

P. A. Patsis, T. Manos, L. Chaves-Velasquez +2

We investigate the evolution of phase space close to complex unstable periodic orbits in two galactic type potentials. They represent characteristic morphological types of disc gal…
