Zoom-in cosmological hydrodynamical simulation of a star-forming barred, spiral galaxy at redshift z = 2 [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present gas and stellar kinematics of a high-resolution zoom-in cosmological chemodynamical simulation, which fortuitously captures the formation and evolution of a star-forming barred spiral galaxy, from redshift z ∼ 3 to z ∼ 2 at the peak of the ...

A 3 mm Spectral Line Survey toward the Barred Spiral Galaxy NGC 3627 [PDF]
Astrophysical Journal Supplement Series, 2019 We conduct spectral line survey observations in the 3 mm band toward a spiral arm, a bar-end, and a nuclear region of the nearby barred spiral galaxy NGC 3627 with the IRAM 30 m telescope and the Nobeyama 45 m telescope.

Asymptotic orbits in barred spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We study the formation of the spiral structure of barred spiral galaxies, using an $N$-body model. The evolution of this $N$-body model in the adiabatic approximation maintains a strong spiral pattern for more than 10 bar rotations. We find that this longevity of the spiral arms is mainly due to the phenomenon of stickiness of chaotic orbits close to ...

Dynamical rules for barred spiral galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1985 Des integrations numeriques des orbites-2D demontrent que la famille principale d'orbites periodiques dans les forts potentiels barres est la famille parallele prograde. Toutes les autres familles ont des distributions de la densite des orbites qui sont incompatibles avec le potentiel impose.
