Constraining the extra heating of the Diffuse Ionized Gas in the Milky Way
The detailed observations of the diffuse ionized gas through the emission lines Hα, [NII], and [SII] in the Perseus Arm of our Galaxy by the Wisconsin Hα Mapper (WHAM)–survey challenge photoionization models. They have to explain the observed rise in the line ratios [NII]/Hα and [SII]/Hα. The models described here consider for the first time the detailed observational geometry toward the Perseu...
متن کاملChemodynamical Simulations of the Milky Way Galaxy
We present chemodynamical simulations of a Milky Way-type galaxy using a selfconsistent hydrodynamical code that includes supernova feedback and chemical enrichment, and predict the spatial distribution of elements from Oxygen to Zinc. In the simulated galaxy, the kinematical and chemical properties of the bulge, disk, and halo are consistent with the observations. The bulge formed from the ass...
متن کاملBlack holes in the milky way galaxy.
Extremely strong observational evidence has recently been found for the presence of black holes orbiting a few relatively normal stars in our Milky Way Galaxy and also at the centers of some galaxies. The former generally have masses of 4-16 times the mass of the sun, whereas the latter are "supermassive black holes" with millions to billions of solar masses. The evidence for a supermassive bla...
متن کاملGalaxy Formation: Clues from the Milky Way
Stellar Populations are the fossil record of Galactic evolution. Interpretation of this record in the Local Group allows one to determine reliably the dominant physics controlling the evolution of those galaxies which are typical of the luminosity in the Universe, and is an essential prerequisite to understanding necessarily limited data at high redshifts. In our Galaxy, the key issues are the ...
متن کاملThree-Dimensional Distribution of the ISM in the Milky Way Galaxy: II. The Molecular Gas Disk
We created a three-dimensional distribution map of molecular gas throughout the Milky Way Galaxy using the latest CO(J =1–0) survey data cube and rotation curve based on the kinematic distance. The radial distribution of the molecular gas shows a central peak and a second peak around 0.5 R0. The thickness of the molecular disk slightly increases from 48 pc to 160 pc with the galactocentric dist...
