Milky Way: structure via live potentials

چکیده
Abstract We use the AREPO numerical code to model structure of a Milky Way like galaxy (MW) via suite simulations composed stellar disc and bulge, dark matter halo, gaseous under isothermal conditions. For each model, we produce longitude velocity ( l-v ) maps gas surface densities extract skeletons main features (arms, bar), contours defining terminal velocities gas. compare these with observations number diagnostic tools, select that best reproduces observed Way.

Milky Way
7 Globular clusters and Population II stars are fossil remnants of the first major epoch of star formation in the Milky Way. SIM Lite will determine precise distances to selected Pop II objects to define a reliable distance scale, and establish reliable absolute and relative ages. Those ages set a minimum age for the Universe and map the early formation history of the Milky Way. The resultant a...
متن کاملProduction of Milky-way Structure by the Magellanic-clouds
Previous attempts at disturbing the galactic disk by the Magellanic Clouds relied on direct tidal forcing. However, by allowing the halo to actively respond rather than remain a rigid contributor to the rotation curve, the Clouds may produce a wake in the halo which then distorts the disk. Recent work reported here suggests that the Magellanic Clouds use this mechanism to produce disk distortio...
متن کاملThe spiral structure of the outer Milky Way in hydrogen.
We produce a detailed map of the perturbed surface density of neutral hydrogen in the outer Milky Way disk, demonstrating that the Galaxy is a non-axisymmetric multiarmed spiral. Spiral structure in the southern half of the Galaxy can be traced out to at least 25 kiloparsecs, implying a minimum radius for the gas disk. Overdensities in the surface density are coincident with regions of reduced ...
متن کاملMilky Way Gas Dynamics
The Milky Way is made up of a central bar, a disk with embedded spiral arms, and a dark matter halo. Observational and theoretical constraints for the characteristic parameters of these components will be presented, with emphasis on the constraints from the dynamics of the Milky Way gas. In particular, the fraction of dark matter inside the solar radius, the location of the main resonances, and...
متن کاملEffect of the Milky Way on Magellanic Cloud Structure
A combination of analytic models and n-body simulations implies that the structural evolution of the Large Magellanic Cloud (LMC) is dominated by its dynamical interaction with the Milky Way. Although expected at some level, the scope of the involvement has significant observational consequences. First, LMC disk orbits are torqued out of the disk plane, thickening the disk and populating a sphe...
